Introduction
Grid and CoreGRID
After more than a decade, the Grid
has evolved from being considered a
technical solution for high performance
computing to a more general concept
of providing computing resources to a
larger spectrum of applications such as
e-science, e-engineering or e-business.
The Grid has been one of the key
enablers of ideas that contributed
to the perception of the Internet not
only as a set of interconnected, locally
managed, computing systems but
also as a single computing system
in which it is possible to manage
resources and security based on global
policies. Grid can provide users with
an enormous on-demand computing
system made up of computers, data
repositories, software, instruments
and sensors; all of them linked by the
Internet. This unprecedented level of
computing power will stimulate the
creation of new, possibly unforeseen
applications. Today, we know only
few of them but it is expected that
in the next ten years more and more
applications will be developed and
made available to Internet users.
At present, one can envision the
merging of different technologies
such as peer-to-peer (P2P), Grids
and service-oriented infrastructures
in the Next Generation Internet.
CoreGRID is a European research
network that is developing the
foundations, software infrastructures
and applications for large-scale,
distributed Grid and P2P technologies.
CoreGRID started its activities in
September 2004 with an ambitious
goal: to build a sustainable research
laboratory gathering the best European
experts, with a view to addressing
the numerous research challenges
posed by large scale computing
infrastructures such as service oriented
infrastructures, P2P systems and Grids.
Starting with 42 partners and 280
researchers and PhD students, it
includes today around 330 researchers
and PhD students from 46 European
research institutions either acting as full
members or associated members. The
first year involved mainly the setting-up
of the network while the second year
was dedicated to its consolidation.
The third year, covered by this annual
report, has been focusing on the
sustainability of the network since it
will only be funded by the European
Commission (EC) for a maximum of
four years, until end of August 2008.
In its first three years, the network
has achieved tremendous results in
terms of integration, working as a
team to address research challenges,
and to produce high quality research
results. During the third year, it
published about 60 CoreGRID Technical
Reports presenting the outcome of
the integration effort. This represents
the same number of technical reports
that were produced during the first
two years. Many of these reports were
published in well-known scientific
journals and presented at international
workshops and conferences. The
network was involved in organising
many scientific events such as internal
meetings and workshops. Some of
these papers appeared in the special
CoreGRID volumes published by
Springer. One of the main milestones
was the organisation of the first
CoreGRID Symposium jointly with the
EuroPar 2007 international conference
in Rennes in July 2007. Based on the
success of this event, the network is
organising a similar symposium in 2008,
again jointly with EuroPar. Mobility of
researchers is key to the success of the
network. Seventeen young researchers
benefited from the fellowship
programme, working for several months
with other CoreGRID researchers, while
twenty researchers took advantage
of the exchange programme to
spend several weeks/months at
another CoreGRID partner’s location,
participating in collaborative research.
CoreGRID has now reached a highly
visible position: it is recognised
worldwide and is the envy of many
of our colleagues outside Europe. We
have evidence to substantiate this

claim, such as the number of visitors
from outside Europe who consulted
our web site to get access to our latest
results or the database of more than
1,050 references by CoreGRID researchers
available on-line. CoreGRID is also well
connected to international initiatives in
those areas and has sponsored several
organisations including the Open Grid
Forum, and international scientific events
such as conferences and workshops.
Although the network of excellence is an
instrument mainly designed to support
research, it is always satisfying for a
researcher to see that his/her work has
been influential in the development of
new technologies and products and has
contributed to the European economy’s
growth. To encourage our researchers to
strengthen their links with the industry
in 2007, the network set up a successful
fellowship programme allowing young
researchers to spend half of their time in
a research organisation that is a CoreGRID
member and the other half in a company,
thus encouraging technology transfer.
CoreGRID also has an Industrial Advisory
Board that has played a key role in the
network to the extent that our research
activities on service-oriented architectures
are attracting of lot of interest from
industry. CoreGRID now has many research
activities that take into account the SOA
(Service Oriented Architecture) paradigm.
“Grid technologies are at a turning point in their
evolution for industry to step in and transform the
world-class research results into key services to drive
European growth in the 21st century.”
“Grid will be a ‘crucial enabling technology’ in achieving
the i2010 (European Information Society 2010) initiative,
which looks to promote cooperation between industry
and Member States in order to achieve a borderless
European information space, stimulate innovation, and
make the European Information Society as inclusive,
secure and accessible as possible.”
“Grids are an excellent enabler of service-oriented
knowledge utilities. However, we must stress the
importance of the co-ordination between the research
and industry sectors to make this a reality.”
“Europe is in an excellent position to shape and steer a
technological revolution via Grid technologies.”

Society and Media, European Commission

Annual

2007
Editorial
This is the third annual report since
the launch of the CoreGRID Network of
Excellence which has one more year to
run before completing its first phase
as an EC- funded project. Although the
main objective was to solve research
challenges in the area of Grid and P2P
technologies, the network has adapted
its research roadmap to include new
challenges related to service-oriented
infrastructures, which are very relevant
to the European industry as illustrated
by the NESSI initiative, the European
Technology Platform on Software and
Services. Although CoreGRID carries the
FP6 label, this emphasis has allowed
the network to take into account
some of the on-going 7th Framework
Programme objectives, in particular
those setting software services as one
of the main priorities. The Grid research
community has not only embraced but
also contributed to the development
of the service-oriented paradigm to
build interoperable Grid middleware
and to benefit from the progress made
by the service research community. For
instance, the Grid research community
has taken a leading role in the
development of standardised services.
• The Programming Model
(PM) Institute is exploring
interactions between the Service
Component Architecture and
its Grid Component Model.
• The Architectural Issues (AI) Institute
is investigating software aging and
rejuvenation techniques applied
to service infrastructures as well
as working on virtualisation for
self-healing in Service Oriented
Infrastructure (SOA) frameworks.
• The Grid Information, Resource
and Workflow Monitoring
Services (GIRWMS) Institute
provides workflow and service
execution management through
advanced techniques for service
adaptation and maintenance
based on SOA standards.
• The Resource Management and
Scheduling (RMS) Institute has
developed expertise in the area of
Service Level Agreement (SLA) within
the network, which is now embodied
into a new integrated project (SLA@
SOI) linking CoreGRID experts to
specific industrial requirements.
These are just some examples of
the network’s research activities
that have good potential in
terms of technology transfer.
As you probably noticed in this
editorial, CoreGRID researchers do not
live in ivory towers addressing only
long-term research challenges without
any link to, or input from, industry
and its requirements. CoreGRID
has acknowledged the move from
Grids to service infrastructures
where Grids are now seen as one
instance of a service infrastructure.
This shift in focus will place the
network in a prime position to be
instrumental in the development
of the SOA paradigm. CoreGRID
will indeed contribute to the
promotion of the European software
industry by encouraging the early
adoption of the service paradigm.
So stay tuned, and watch this
space to see new initiatives coming
from CoreGRID in the area of
software services in the following
months, especially in relation to
the network’s sustainability plan.
CoreGRID has several ongoing
research activities related to software
services and is playing a key role
in contributing to the growth of the
European economy. As an illustration,
the network can highlight the
following research activities taking
place in our research institutes:
• The Knowledge and Data
Management (KDM) Institute has
developed the Core Grid Ontology
to provide the infrastructure
for knowledge-based, dynamic
service composition, enabling
the unambiguous, machineinterpretable advertising of services,
and facilitating their discovery.

CoreGRID
Network
of Excellence
CoreGRID is helping
Europe to take Grids
out of research labs
and into industry.
Four Years of CoreGRID Achievements
CoreGRID concept
The CoreGRID Network is funded by
the European Commission within the
European Union’s Sixth Framework
Programme for research and
technological development. A grant of
€8.2 million has been assigned to the
project for a duration of four years.
CoreGRID comes under the framework
of Europe’s Information Society
Technologies (IST) thematic priority.
IST has defined Grid technologies
as a crucial objective that will
transform the European Union into
the most competitive knowledgebased economy in the world.
By providing everyone with
immense computing power and
knowledge – currently unavailable
to even the largest corporations and
laboratories – Grids will improve
the competitiveness of European
industries and mark a new era of
markets and services previously
perceived as impossible to drive
forward. The impact on our quality of
life will be profound, allowing us to
better monitor and model everything
from global climate change to the
way cars behave in collisions.
In order to put Europe in front and
make sure today’s research addresses
tomorrow’s market needs, CoreGRID
is committed to structuring European
research by integrating a critical mass
of expertise and promoting scientific
and technological excellence within and
beyond the Grid research community.
Through this commitment, CoreGRID
is helping Europe to take Grids out
of research labs and into industry.
This initiative marks a critical step
in ensuring that Europe realises the
benefits of the information society.
CoreGRID objectives &
structure
Launched on September 1, 2004, the
CoreGRID initiative aims at building
a virtual Europe-wide research
laboratory that will achieve scientific
and technological excellence in the
domain of large-scale, distributed
Grid and peer-to-peer technologies.
The primary objective of the
CoreGRID Network of Excellence is
to build solid methodological and
technological foundations for Grid
and peer-to-peer, and to stay at the
forefront of scientific excellence.
This objective will be achieved
by structuring integrated research
activities carried out by experts in
parallel and distributed systems,
middleware, programming models,
algorithms, tools and environments.
This joint research will contribute to
realising the CoreGRID vision of a
future Grid infrastructure: seamless
integration of the existing Grid and
other emerging architectures (such
as peer-to-peer) using concepts
and standards from the World
Wide Web Consortium and other
relevant standardisation bodies.
To comply with this long-term
objective, the CoreGRID Network
runs a joint programme of activities
(JPA). The JPA integrates and
co-ordinates the activities of the
major European research teams
in the field of Grid and peer-topeer technologies. Composed of
well-established researchers (161
permanent researchers and 164 PhD
students) from 46 research centres
and universities, the CoreGRID
research teams bring high-level
expertise in specific areas. They also
influence their national Grid and
peer-to-peer programmes, fostering
better long-term integration.

KNOWLEDGE AND
DATA MANAGEMENT
▼
Grids are changing their role, moving from a
computation and data management platform to a
pervasive information and knowledge management
infrastructure. This trend requires new models,
services and technologies for enabling Grid
computing systems to manage distributed data
and knowledge, enabling complex applications
according to the SOKU model.
The INSTITUTE ON KNOWLEDGE AND DATA
MANAGEMENT (KDM) joins together thirteen
institutions from eight European countries and
involves more than 50 senior researchers and PhD
students. The general goal of this Institute is to
further integrate data management and knowledge
discovery solutions with Grid technologies for
providing data- and knowledge-intensive Grids.
The general goal is to
further integrate data
management and
knowledge discovery
solutions with Grid
technologies.
The Institute provides a collaborative
setting for European research
teams working on: distributed
storage management on Grids;
knowledge techniques and tools
for data-intensive applications;
security and trust mechanisms for
storage and data; and integration
of data and computation Grids with
information and knowledge Grids.
The goal of the second year has
been to consolidate and expand
the joint activity of research groups,
thus promoting larger leading
teams and supporting efforts
towards standard models, services,
middleware and solutions.
During the third year, the Institute
members (CETIC, FORTH, CNR-ICAR,
INFN, CNR-ISTI, PSNC, STFC-RAL,
SZTAKI, Universidade Nova de Lisboa,
University of Calabria, University of
Cyprus, University of Manchester,
and University of Newcastle)
worked on three main tasks:
1 DISTRIBUTED STORAGE
MANAGEMENT
Providing infrastructures, techniques
and policies for managing distributed
storage resources in the Grid.
2 INFORMATION AND KNOWLEDGE
MANAGEMENT
Developing metadata, semantic
representation and protocols for
Grid service discovery, information
management and design of
knowledge-oriented Grid services.
3 DATA MINING AND KNOWLEDGE
DISCOVERY
Designing Grid services for distributed
data mining and knowledge discovery
on Grids and P2P systems.
In all those areas in 2007 the partners
jointly produced scientific results
implemented in software prototypes
and published in scientific journals
and conference proceedings.

Additionally, security issues have
been covered with a particular focus
on security requirements and models
for storage and data management.
Objectives
The main objective of the KDM Institute
is to address issues like representation,
discovery and integration of data and
knowledge in Grids and P2P systems.
The Institute’s approach is a vertical
approach that encompasses all layers
involved with knowledge management
in Grids: storage management
at the systems-level, information
and knowledge management, and
knowledge discovery. At the same
time, single KDM solutions that bring
benefits to the Grid community have
been designed and developed.
A key KDM objective is to design
and develop common solutions for
data management and knowledge
discovery and management on Grids.
This promotes the wide diffusion
and use of knowledge-based Grid
services for the Semantic Grid and
the Knowledge Grid. To this end,
the partners of the KDM Institute
focus on the problems of providing
commodity-based connectivity among
heterogeneous distributed storage
devices, management automation
of administration tasks traditionally
handled manually, and storage
virtualisation for serving well-defined
requirements from multiple users.
Another challenge we investigated
is the need to develop autonomous
security mechanisms for decentralised
data management involving selforganising behaviour. Finally, significant
results have been achieved in topics
such as data federation, integration
and querying, dynamic workflow
execution, Grid-aware knowledge
discovery, and P2P data management.
As a result of the joint activities, new
research results, software prototypes
and system solutions have been
developed in such areas as storage
management, distributed data
integration, reliable dynamic query
processing, storage security models,
knowledge discovery services, Grid
ontology, and P2P data management.
We organised Institute meetings and
workshops jointly with other CoreGRID
Institutes, exchanged visits, set up joint
fellowships, and produced two books,
as well as tens of publications and
technical reports. We organised joint
research activities for research groups
working on the main KDM topics. Joint
activities are carried out with other
CoreGRID Institutes on scheduling for
data Grids, self-configuring storage,
scalable Grid services, resource
discovery, and P2P Grids. We also
contributed to the EC Technical
Group 5 on Data Management.
Industry
added-value
The results of the research activities
of the KDM Institute can be exploited
by European industries working
in the area of data management
and knowledge services. Research
activities in the area of data Grids and
knowledge Grids are being pursued
by many industries such as HITACHI,
Microsoft, IBM, SAP, ORACLE, and
SIEMENS. This is testimony to the
industrial relevance of KDM topics.
KDM Institute partners started new
national and European joint projects
in KDM research areas. CoreGRID
partners submitted together with
industrial partners project proposals
for building knowledge and data
management solutions made largely
usable through Grid services. Security
and service level agreement issues are
also investigated. Institute partners
worked with IAB member companies
on proposing CoreGRID fellowships
in KDM areas of industrial interest.
Challenges and
perspectives
Developing knowledge-based
applications that exploit Grid features
to achieve high performance and
high availability is an area of active
research in Europe and overseas.
Industry is also very active in
exploring and adopting new solutions.
CoreGRID KDM researchers will
work towards providing a variety of
models, architectures, prototypes,
and services offering different
technological solutions to current
problems faced by Grid applications.
Future research activities will focus
on core technologies needed for
implementing the SOKU model,
including ontologies, data mining
and knowledge discovery, and
data management, also taking
into account SLAs. Partners of
the KDM Institute will proceed
beyond the funded period and will
continue their joint activities.

PROGRAMMING MODEL
▼
Programming Model Institute: making the programming of Grid infrastructures as simple, transparent
and efficient as possible.
While Grid tool technology is rapidly
converging towards Services and
Service Oriented Architectures,
advanced programming environments
are still needed that may simplify
the Grid programmer’s task and
shorten the application design-toproduction time while outperforming
applications written using plain,
low-level Grid middleware tools.
The Programming Model Institute
aims to investigate new Programming
Models capable of fully supporting
efficient Grid programming, and
to raise the level of abstraction
provided to the Grid application
programmer as recommended in
the NGG documents.
The Programming Model Institute
brings together 13 full partners
and 2 associate partners, with a
total of more that 45 researchers
and about 30 PhD students.
Altogether, these researchers
have contributed to an extensive
programme of short visits, to the
researcher exchange programme,
to CoreGRID fellowships often
involving other CoreGRID Institutes,
and have published a significant
number of joint research papers
in international journals and
presented them at conferences.
The Programming Model Institute
investigates suitable Grid programming
models and techniques based on
component technology. Components
and services are becoming ever
closer and common perspectives
may be exploited in the design
of advanced component-based
programming frameworks supporting
full interoperability with services.
Within the Institute, the GCM (Grid
Component Model) has been defined
and is currently being refined. A spinoff STREP project has been started
(Jun06 – Nov08) whose main goal is
the implementation of an open source
prototype implementation of GCM.
GCM builds on top of the Fractal
component model and offers to
the Grid application programmer
hierarchical component composition,
autonomic controllers, advanced and
collective component communication
patterns, as well as an XML based ADL.
Within the Programming Model
Institute, ISTI/CNR, HLRS, IC, INRIA,
QUB, WWU Muenster, UCHILE, UNIPASSAU, UNIPI, EIA/FR, UOW, UPC,
VUA, UoS and UoL have actively
participated in the activities of
the three main research topics
covered by the Institute: “Basic
Programming Models”, investigating
the Programming Models suitable
for programming primitive GCM
components; “Components
and hierarchical composition”,
investigating the basic features of
GCM; and “Advanced Programming
Models”, investigating the possibility
of building advanced Programming
Models on top of GCM.
In 2007, the activities in the
Programming Model Institute have
been mainly centred on a couple of
CoreGRID events (the workshop coorganised by the Architectural Issues:
Scalability, Dependability, Adaptability
Institute, by the Programming Model
Institute and by the Grid Systems,
Tools and Environments Institute in
Heraklion in June; and the CoreGRID
Symposium in Rennes in August)
and on a quite large number of
17
short visits and Research Exchange
Programme events involving Institute
researchers from different partners. All
of the Institute partners participated
in the Heraklion workshop and most
of them also participated in the
CoreGRID Symposium, presenting
several important research results
and discussing with partners both
existing and new research topics
in the Institute. Overall, several
notable results have been achieved
in 2007, concerning GCM mechanism
and structure refinement and
related to GCM-based advanced
programming models and GCM
verification/modelling techniques.
The advances in Programming Model
Institute activities contributed to the
CoreGRID goal of providing solid
methodological and technological
foundations for Grid and peer-to-peer.
The GCM model is being adopted and
used in several other Institutes within
the NoE. GCM-related results have been
presented and appreciated in a number
of international contexts, including
SuperComputing07 and EuroPar07
conferences, OGF (Manchester07) and
the CoreGRID Scientific Advisory Board.
The results achieved during 2007
contributed to the well-focused
objective of the Programming Model
Institute that may be summarised as
being able to deliver a definition of a
component programming model that
can be usefully exploited to design,
implement and run Grid applications
while efficiently and transparently
facing the new challenges in terms
of programmability, interoperability,
code reuse and efficiency that derive
from the peculiar Grid features such
as heterogeneity and dynamicity.
During 2007, partners of the
Programming Model Institute:
• Demonstrated autonomic
managers taking complete care
of performance related (nonfunctional) aspects of notable
composite components.
• Refined several formal and
semi-formal techniques that
allow reasoning about GCM
programmes and proof of
properties of these programmes.
• Achieved further results related
to the usage of “data sharing”
and “data flow stream” ports
among GMC components.
• Demonstrated the possibility of
combining classical parallelisation
techniques (such as loop
transformations) with structured
programming environments that can
eventually be built on top of GCM.
• Started to demonstrate
interoperability of GCM
concepts with software services
and SOA in general.
• Finally, during the GRIDS@
work event in Beijing (end
of October) the preliminary
prototype developed by
GridCOMP demonstrated the
ability to efficiently deploy and
run component programmes
on hundreds of distributed
Grid resources. This is not
directly a CoreGRID result,
although most GridCOMP
partners are also partners of the
Programming Model Institute.
These results have been achieved by
partners of the Institute cooperating
via all the mechanisms provided
by CoreGRID (short visits, REPs,
fellowships) and clearly contribute
to the Programming Model Institute
objective. In turn, the main objective
in the Programming Model Institute
contributes to the overall CoreGRID
roadmap both in the field of tools
and environments for efficient Grid
programming and in the field of
methodologies for the development
of suitable Grid software. The GCM
is in fact being used as a reference
model in the Grid Systems, Tools
and Environments Institute. GCM is
also being considered as a suitable
programming model to develop
several kinds of (system) applications
in other Institutes in the NoE.
Through participation in GridCOMP,
several industrial partners have
been involved in the GCM design
and development process. The
Programming Model Institute
builds on these experiences in
such a way that the final GCM
could be immediately used in
typical industrial applications
without any further tuning.
Also, a standardisation process has
been initiated through ETSI that will
eventually result in a complete GCM
standard. In 2007, the first steps have
been performed and the GCM ADL
is close to being an ETSI standard.
We expect that Programming Model
Institute activities, and those
concerned with GCM in particular have
a twofold impact on industry: on one
hand, the availability of a complete,
advanced, component-based Grid
programming environment will allow
industry to cut the development time
and cost of Grid applications. On the
other hand, complete interoperability
with the services framework (one of
the objectives of the Programming
Model Institute yet to be achieved)
will allow industry to reuse and
exploit a large base of already
developed software services in a more
convenient programming framework.
There are still several open
challenges to be tackled in the
Programming Model Institute:
• Complete integration of GCM with
the software service framework.
Although Institute partners already
partially demonstrated the feasibility
of porting GCM concepts on top of
the Service Component Architecture,
much work has to be done to
guarantee that the advanced
concepts introduced in GCM (such
as collective communication
patterns or autonomic managers)
can be migrated to the
software service scenario.
• Implementation of advanced
programming models on top of GCM.
There are several kinds of advanced
programming models considered to
further raise the level of abstraction
presented to Grid application
programmes, ranging from skeletonbased structured programming
paradigms to component paradigms
combining spatial (componentlike) and temporal (à la workflow)
composition of components.
• Development of a complete set of
formal (or semi-formal) tools that can
be used to reason about and prove
properties of GCM programmes.
Partners in the Programming Model
Institute recognise these are significant
challenges still to be addressed. During
the Institute meeting in Heraklion
(June) partners also agreed that the
activities needed to tackle these
challenges must be continued after the
end of the NoE, either on a volunteer
basis or within possible further
initiatives and projects following the
(formal) end of the CoreGRID NoE.

The main goal of the Institute on Architectural
Issues (System Architecture - SA) is to provide the
techniques that will pave the way towards scalable,
adaptable, and dependable Grid architectures and
services meeting the mandatory properties of the
Next Generation Grids.
The Institute on Architectural Issues joins together
thirteen partners from eleven different European
countries and involves more than 60 senior researchers and PhD students. During the past year of
the project, two CoreGRID associated members,
CNR-ICAR and the University of Sannio, both from
Italy, joined the SA Institute.
The principal goal of the SA Institute
is to perform research on particular
aspects of the Grid technologies for
providing basic building blocks for
future Grid architectures - scalability
and P2P technologies, dependability;
and adaptability/self-management
- which meet the mandatory properties
of Next Generation Grids. The ultimate
challenge is to make the Grid
scalable, dependable and adaptable
by devising novel mechanisms and
proposing improved techniques.

The research activities of the Institute
evolve around the following five
tasks with well-defined objectives:
1. P2P-Based Services and
Resource Discovery
Providing new solutions for
resource location and discovery
on Grid systems based on the
P2P paradigm, comprising
techniques with mobile agents.
2. Self-Organising Grid Services
using P2P Technology
Designing techniques using
composition of services
and semantic planning.
3. Dependability Mechanisms
for Computational and
Data Desktop Grids
Developing dependability
mechanisms for scalable
Grids comprising two different
types of applications and
middleware: computational
Grids running on public Internet
resources (i.e. desktop Grids)
and data/service Grids.
4. Fault-tolerance and Robustness
Studying the impact of faults on
distributed applications, targeting
platforms such as clusters and Grids.
5. Adaptive Management of
Systems and Resources
Developing mechanisms for
automated adaptation and
self-management of the Grids
on all hierarchy levels.
19
Each task comprises two to three
research groups which constitute the
basic building blocks of the Institute.
These tasks define clear-cut objectives
and produce concrete research results.
Moreover, the Institute contributes
towards the horizontal activity on
Trust and Security providing novel
robust mechanisms and techniques
such as checkpointing and recovery
systems. Last but not least, there is
strong contribution to the recently
established horizontal activity on
Service Oriented Architectures (SOAs).
The scientific interaction between the
researchers of the Institute during
the third year of the project produced
more than 40 joint research papers,
many of them published in well-known
international journals and presented
at conferences, while a total of twelve
CoreGRID technical reports have been
published on the CoreGRID website.
One of the publications was selected as
best paper at the 7th IEEE International
Symposium on Network Computing
and Applications (IEEE NCA08).
The workshops and technical meetings
organised by the SA Institute allowed
the dissemination of the scientific
output to other CoreGRID Institutes as
well as to external organisations. In
February 2007, a special issue of the
journal Future Generation Computer
Systems (FGCS) published selected
papers. During the third year of the
project the CoreGRID Workshop on
Grid Programming Model, Grid and P2P
Systems Architecture, Grid Systems,
Tools and Environments, took place
June 12-13, 2007 at FORTH, HeraklionCrete, Greece. The workshop was
jointly organised by the PM SA and STE
Institutes. A special CoreGRID Springer
volume, to appear soon, will include
selected publications of this workshop.
Objectives
The main objective of the SA Institute
is to significantly improve architectural
designs of Next Generation Grids by
performing collaborative research on
the following key architectural aspects:
• To apply and extend results from
research on peer-to-peer systems for
enabling higher scalability and selforganisation of Grid infrastructures.
• To investigate the mechanisms
for fault-tolerance and robustness
of the Grid infrastructure to
assure reliable Grid services.
• To study methods for adaptability
and self-management in order to
establish paradigms for automatic
and low-cost Grid management.
To achieve scalability we extend the
results from research on peer-topeer systems and propose scalable
approaches for resource discovery. We
propose dependability mechanisms
for all levels of the Grid including
checkpointing and recovery. We
devise techniques for fault tolerance
and robustness for Grid services,
providing a more reliable Grid
architecture. In adaptability and selfmanagement, we develop mechanisms
for automated adaptation and
reconfiguration of Grid infrastructure.
Through these objectives, the SA
Institute aims to contribute to the
mandatory architectural principles
of the Next Generation Grids by
scalability of services, resilience,
straightforward administration and
configuration management.
The scientific highlights of the
SA Institute could be briefly
summarised as follows:
• The design of a hybrid P2P-based
system that works efficiently for
multi-attribute queries on static
and dynamic attributes and its
experimental evaluation on existing
Grid platforms (Grid 5000).
• The development of dependability
mechanisms based on
virtualisation techniques that
lead to zero downtime. The
proposed solution is applicable
to individual servers, clusters,
as well as Grid infrastructures.
• Modelling and prediction of
workloads and system behaviour
with impact to adaptable solutions
for self-managing systems that
provides support for scheduling.
• Refinement of scalable, dependable
and adaptable Grid solutions,
and their experimentation
of real Grid platforms.
• Investigation of the fault conditions
of existing Grid infrastructures (e.g.
EGEE) towards the development
of a framework that will propose
concrete solutions for low-cost
automatic fault management
in Next Generation Grids.
The SELFMAN FP6 EU project is a
spin-off of CoreGRID involving mainly
partners from the SA Institute and
industrial partners. This project is
related to the areas of peer-to-peer
computing and adaptability/selfmanagement. This collaboration
provides the SA Institute with
real-world use cases, especially for
dependability and self-managing
applications. Other EU spin-off
projects were proposed during
the last EU call from partners of
the SA Institute and industry.
Industry
added-value
The IAB members pointed to the
P2P paradigm as a useful example
that could lead to real scalable
solutions in Next Generation Grids,
while emphasising the importance of
dependability for high quality service
provision and low cost automated
self-management. The remarks of the
IAB members provide strong indication
that currently the research work within
the SA Institute has the right focus
while the produced results lead to
solutions of interest to industry.
Achievements
and perspectives
Several obstacles have to be overcome
before the objectives of the Next
Generation Grid are achieved. Grids
have to become more robust and
pervasive. The challenges faced by the
SA Institute for System Architecture
constitute the cornerstone upon which
any Grid middleware should be built.
During the CoreGRID project, concrete
solutions and major steps have been
made towards the invisible Grid.
The researchers involved in the SA
Institute of CoreGRID are determined
to work together after the end of the
NoE as witnessed by the responses
to the sustainability questionnaire.
Currently, the partners explore the
possibility to define common FP7
projects to ensure the viability of the
strong bonds that were developed
during the duration of CoreGRID. Most
promising appears to be the track on
Software Services. Another promising
direction on which much of the future
focus of the Institute will be directed
is the Desktop Grids. An FP7 proposal
entitled EDGeS: Enabling Desktop
Grids for e-Science has been approved
for a number of partners of the SA
Institute with the aim to integrate
the advantages of two important Grid
concepts: service Grids like EGEE and
Desktop Grids. In another effort a
FET project was proposed aiming to
support self-evolving, self-describing
service-oriented systems, in order to
make them suitable for the new era
of knowledge aggregation, support
for user-oriented social networking
and pervasive IT infrastructures.

GRID INFORMATION,
RESOURCE AND WORKFLOW
MONITORING SERVICES
▼
The idea of the Grid Information, Resource and
Workflow Monitoring Services architecture is to
convey all the data through the information service
in order to have a standard interface across different
administrative sites and services. The characterisation
of the required information service greatly depends
on such factors as the demand placed on the source
of information (e.g. static versus dynamic, publication
rate), its purpose (e.g. discovery, logging, monitoring)
and QoS requirements.
One of the main goals of the Institute
on Grid Information, Resource and
Workflow Monitoring Services (IRWM)
is to cooperate with other activities
providing basic features for the overall
Grid architecture. This synergy is to be
expected especially with Knowledge
and Data Management, Resource
Management, Programming Model,
Grid Systems, Tools and Environments.
IRWM services are essential to other
Institutes as they provide data for
evaluating the efficiency of systems
and tools resulting from their
research. IRWM services also support
the core functionality necessary for
production-based Grid environments.
The IRWM Institute involves 13
CoreGRID partners (FHG, FORTH,
INFN, INRIA, PSNC, SZTAKI,
UMUE, UNICAL, UIBK, UMEA,
The work is mostly organised into
research groups, units of two or
more CoreGRID partners collaborating
closely together on common goals.
Joint technical reports, publications
and prototype implementations are
the major measurable outcomes. One
of the new researches is devoted to
modelling dynamic workflow structures
in higher order chemical languages.
The IRWM has a new partner, the
University of Innsbruck (Austria),
which joined CoreGRID at the end
of 2006 and two new associate
partners joining IRWM in 2007:
the University of Sannio (Italy)
and Umeå University (Sweden).
Objectives
The primary objective of the IRWM
Services research group is to study
and provide general information
and services for the underlying Grid
management required by the Next
Generation Grid. The Grid management
services considered here include Grid
core services and components. During
the project the partners of the IRWM
defined several specific objectives
which allow us to work out the major
goals, among others: providing
multi-grain and dynamic monitoring for
Grid resources and services, enabling
reliable online monitoring of status
and performance for a wide range of
resources, support for extraction and
representation of job workflows from
programming models, framework for
user management and user and job
separation, supporting kernel and
application level checkpointing.
The Institute is focused on the
following major objectives:
21
• Providing network
infrastructure monitoring
• Providing monitoring of the progress
of complex job workflows
• Support for extraction and
representation of job workflows
for programming models
• Realising middleware support for
complex job workflow execution
• Framework for user management
and user and job separation
• Supporting accounting services
in virtual environments
• Providing checkpoint restart
functionality in heterogeneous
environment supporting
dynamic job migration
• Supporting kernel and application
level checkpointing.
Achievements
The integration work and co-operation
between three Institutes (IRWM, KDM
and RMS) were presented at the
joint CoreGRID workshop in 2007 (in
conjunction with ISC 2007) with a
first publication released in 2007.
A paper describing the IRWM
general architecture was awarded
by the Programme Committee
at the WEBIST 2007 conference
(International Conference on Web
Information Systems and Technologies,
Barcelona, Spain, March 2007).
One of the main challenges when
deploying a Grid workflow management
system in a production environment
is the integration of the workflow
solution with existing resources, data,
information, and knowledge. The last
report in 2007 with the title “Report
on workflow integration with resource
management and data and knowledge
management” gives an overview of
different aspects that are related to
this challenge and presents a set of
research and development activities
performed by CoreGRID partners.
Three CoreGRID institutes co-organised
in 2007 the 2nd CoreGRID Workshop
on Grid Middleware in conjunction
with ISC 2007 conference (Dresden,
June 2007). 22 papers were accepted
by the Programme Committee from
CoreGRID and the external community.
The conference proceedings are under
publication in CoreGRID book series
in co-operation with Springer.
The outcome of IRWM integration work
can be found in several national and
international projects like CancerGrid,
MediGrid, BalticGrid, Progress.
Relations to
industry
IRWM delivered three major reports
about the results on the joint research
topics of all research groups, including
implementation of prototypes and
the outcome of the integration of
IRWM services with other architectures
developed by CoreGRID Institutes.
The possibility of accounting the
resources used in Grids forms the
basis for introducing the Grid economy
concept. Contacts with industry allow
us to prepare use cases which are of
importance not only in the scientific
community. We are in close relations
with representatives of the Industry
Advisory Board. The last face-to-face

direct feedback from industry (e.g.
Oracle and LMS International) with
special attention on workflows,
checkpointing, and accounting services.

In addition several partners
started related (national or
international) projects which use
the CoreGRID integration work.
We integrate mainly middleware
services with emphasise on reliability
and scalability in production-based
Grid environments. This is of crucial
importance for industry related
applications where used infrastructure
should deliver a reliable set of services.
It was actually applied in our cooperation with Telecom companies (e.g.
Telecom in Italy - network monitoring;
France Telecom - reliability in Grids;
Silicon Graphics - reliability of operating
systems supported by checkpointing).
Challenges
in 2008
IRWM will present the outcomes of
integration work between institutes
at the 3rd CoreGRID Workshop on Grid
Middleware organised in parallel to
OGF23 (Barcelona, June 2008). The
conference proceedings will be the
basis of our final report, including an
overall architecture of Grid services.
In addition a white paper will be
produced on Grid checkpointing.
The Grid Workflow Forum (maintained by FHG) and
Checkpointing Portal (maintained by PSNC) propagate the

Grids and Service-oriented
Infrastructures (SOI) became common
core technology for scientific and
commercial environments. The
management of large-scale distributed
infrastructures is an increasingly
complex task, especially considering
the increasing requirements for new
and feature-rich applications such
as workflows and process chains.
Suitable solutions for resource
management are essential to support
a flexible and efficient infrastructure
that is easy to use but also supports
many scenarios. Scheduling is the
task of automatic planning and
steering the resource utilisation for
different applications or jobs.
23
Objectives
The Institute works on several
research aspects to provide complete
solutions in this area. This includes
the architectural perspective on how
a suitable Grid scheduling architecture
should be structured and implemented,
but also on the algorithmic side
towards efficient scheduling algorithms
for different application use cases.
These main objectives are achieved in
several research tasks that focus on
specific aspects. In order to provide a
common and generic solution for Grid
scheduling and management in Grids
and Service-oriented Architectures
(SOA), the Institute addresses
the following research tasks:
impact of the collaboration on the
individual research work. However,
the Institute not only demonstrated
its success in scientific publications,
but also developed and implemented
many practical solutions. Scheduling
solutions have been created for
different production Grid installations
linking technologies and expertise
from several CoreGRID partners. These
include the eNanos extension with
GRMS and the integration of MSS/Viola
features to SwissGrid’s ISS. Many more
examples can be found on the Institute
webpage and the provided reports.

The Institute was able to link the
individual work of the participating
researchers and accelerate the
joint work on new solutions. The
productivity of the Institute in 2007
can be seen in the scientific output:
the partners published 16 technical
reports, 39 joint papers and 72
individual publications. This is a
significant increase in comparison
to the previous years and shows the
interoperability link many different
areas. Part of this work took place
within CoreGRID connecting several
different Institutes like the Institutes
on Knowledge and Data Management
and on Grid Information, Resource and
Workflow Monitoring. This collaboration
also led to the joint organisation of
the second CoreGRID Workshop on
Grid Middleware which will take place
in 2008. Work on interoperability
and protocol specification was done
in the Open Grid Forum and as such
involved a broader audience. The main
activity areas of the Institute in the
OGF were in the GRAAP, OGSA-RSS,
and GSA working and research groups.
Such joint and focused collaboration
of European researchers was made
possible by the CoreGRID network.
Here, the Institute facilitates interaction
between researchers from different
places and supports their collaboration
with meetings, mobility and exchange
programmes, and fellowship positions.
Moreover, natural integration of the
researchers’ varying expertise links
participating individuals in joint
research groups. These collaborations
extend beyond the network and
Institute and facilitate new projects
and joint research agendas.
The Institute members are highly
committed to the idea of creating a
joint European Research Institute.
Industry
added-value
A specific focus lies in the consideration
of industrial requirements and the
support of business-oriented scenarios.
Thus, the Institute addresses several
aspects like service level agreements,
cost integration, accounting and billing
which are essential to providing the
foundation for integrating commercial
service providers in future Grids. The
work on service level agreements has
already produced reports on technology
survey and infrastructure proposals.
Again, this was also discussed in
the Open Grid Forum. In general the
Institute further evolved the view
of Grid applications into common
SOA/SOI scenarios. There is a general
trend towards convergence of these
different scenarios as the problem
spaces share most of their research
challenges. This can also be seen
in the Institute partners’ activities in
this area. Partners of the Institute are
active in the contemplated integrated
project “SLA@SOI” in FP7 starting in
2008. The Institute included a research
task on “Virtualisation Management”
as this becomes a common feature in
adaptive IT environments which can
be found in commercial and academic
scenarios. Virtualisation of computers
and storage provide new features
and higher flexibility which also need
adequate automatic management
functions which the Institute works on.
Challenges and
perspectives
There are major challenges in the
general adoption of management and
scheduling features in production
environments. The providers of
infrastructures and software solutions
are typically focused on proprietary
solutions. The Institute disseminates
results in collaborations in activities
like the Open Grid Forum, which links
commercial and academic stakeholders.
The partners of the Institute for
Resource Management and Scheduling
have entered major collaborations since
the start of the CoreGRID network. The
regular meetings and joint discussions
have led to a natural exchange of
ideas and work on common topics
of mutual benefit. The partners
are eager and highly committed
to continue these collaborations
beyond the current funding period
of the network. There will be joint
efforts to master the challenge of
research fragmentation in this field.

Objectives
Vladimir Getov
Leader of the Grid Systems,
Tools and Environments Institute,
University of Westminster
The research activities of the STE
Institute are organised in four tasks
with the following objectives:
GRID SYSTEMS, TOOLS
AND ENVIRONMENTS
The research activities of the Institute on
Grid Systems, Tools and Environments
(STE) focus on developing the design
methodology for a generic component
system that integrates application
components, tools/system components,
problem-solving environments (PSE),
portal components, and infrastructure
resources components. The specification
of the Institute’s generic Grid platform
significantly advances the state of
the art. It enables the design of
component-based Grid systems with a
single, seamless and “invisible” Grid
software infrastructure. Our research
results are equally valid for both the
client/server and the peer-to-peer
paradigms. The Institute’s approach
encompasses both the application of the
component model and its integration
into a service-based framework.
The STE Institute involves more
than 80 senior researchers and PhD
students who participate in eleven
research groups for implementing
the Institute’s roadmap.
The STE Institute’s approach enables
the design of reconfigurable Grid
systems with dynamic properties
guaranteed by our componentbased framework. Our flexible Grid
platform is suitable for a wide range
of devices, from portable PDAs to
parallel supercomputers. Beyond the
contributions of the Institute partners,
there exist many individual approaches
for building Grid systems, tools and
environments by other projects.
The STE Institute maintains working
contacts with key projects, proliferates
CoreGRID results, and fosters
collaboration with relevant research
activities in Europe and worldwide.
The STE Institute brings together
twelve partners – IPP-BAS, USTUTT,
ICS-FORTH, IC, INRIA, SZTAKI, UWC,
UNIPI, UOW, UPC, VUA, and CYFRONET
– from ten different European
countries. In addition two new
associated partners – CATNETS and
UNIVIE – joined the Institute in 2007.
Generic Platform: This task addresses
the development of a generic,
component-based platform, with focus
on its architecture, interoperability,
security, and design methodology.
This platform is specifying the basic
“glue” from which higher-level
components and services can be
constructed. Challenges arise from
heterogeneous software libraries,
toolkits, operating systems and existing
Grid frameworks. The specification of
this platform underpins the research
areas of the other three tasks.
Mediator Components: This task is
responsible for designing a component
suite that mediates between the
applications and system layers,
providing core services according to
the architecture of the generic platform.
These include such capabilities as
dynamic application steering, metadata retrieval, and service discovery.
The components delivering these
capabilities are integrated and exposed
via a runtime environment that acts
as a gateway to system components,
thus addressing the integration aspects
of the generic component platform.
Integrated Toolkit: This task is
specifying and designing a toolkit
for simplifying the deployment of
Grid-unaware applications while also
optimising application performance.
More specifically, this involves
defining and mapping application
requirements to the component-based
generic platform as well as providing
application interfaces to the mediator
components. The runtime environment
of such an integrated toolkit is able
to run applications in a Grid and
25

optimise their performance dynamically
in a way transparent for the user.
Advanced Tools and Environments for
Problem Solving: This task involves
designing PSEs or portals that take
legacy software and automatically
deploy it as a service that conforms to
a standard service model. The aim is
to integrate our generic platform into
PSEs and portals allowing users to
compose, steer, monitor and visualise
job execution in a transparent and
simple way. This work is based on
identified deployment scenarios,
using technologies for wrapping
legacy code and mechanisms for
deploying and managing services and
jobs in peer-to-peer environments.
Industry
added-value
Based on the studies performed
within the STE Institute, the following
joined projects have recently been
launched in order to implement the
identified research and development
work. Thus, the STE Institute continues
and expands its research using
the prototype Grid systems under
development by these projects:
• GridCOMP – building an
advanced component platform
for an effective invisible Grid.
• XtreemOS – designing a Linuxbased operating system to
support virtual organisations
for next generation Grids.
• EDGeS – creating a Grid
infrastructure that seamlessly
integrates a variety of desktop Grids
with production service Grids.
Those spin-off projects have been
the main vehicle for applying the
impact of the Institute’s research
activities in industrial environments
with direct contribution to improving
the European economy in the area
of Grid and service technologies. In
addition, the STE Institute has been
involved in the development of fullscale use cases in collaboration with
industrial partners via the currently
active spin-off projects. Our industrial
partners for this activity include Atos
Origin, Grid Systems, and IBM.
Challenges and
perspectives
Currently, the STE Institute is
addressing the following problems
and scientific challenges:
• The combination of applications
and system software to integrated
software assemblies is a central
problem we are addressing. The
aim of this integration is twofold:
(1) to allow applications to better and
more flexibly use Grid resources, and
(2) to enable system services
to effectively steer and
control their applications.
For this purpose, we are designing
and building an integrated
component system that has a
single glue layer between all
forms of components. Thus most
of the complexity of integrating
the many individual software
items will be removed.
• The development of applications
to be run on the Grid is still
difficult, preventing the widespread adoption from non-expert
users. The challenge in this
case is to provide development
and execution environments
for Grid-unaware applications,
where the Grid resources can
be transparently exploited.
• Finally, applications typically have
to be adapted to run on specific
hardware platforms. For improving
performance, the applications have
to be specifically tuned for each
hardware platform. This situation
is not feasible in Grid computing
environments, since the execution
platform can change on a per-job
basis, and even at run time. In
these kinds of environments, the
applications have to adapt to the
systems and resources available.
By now, the STE Institute has reached
the roadmap phase of ongoing,
integrated research, mostly fostered
by joint projects, such as GridCOMP,
XtreemOS, and EDGeS. Having
reached this critical mass of ongoing
research activity, our future steps
focus on achieving sustainability as
part of the CoreGRID network by:
• Coordinating activities for Institute
partners’ participation in national
and international research as well
as industrial projects related to Grid
systems, tools, and environments,
assuming the results of this
Institute as starting points to ensure
stable and durable cooperation.
• Organisation of an annual workshop
to discuss and present new
developments in the area of Grid
systems, tools, and environments.
• Maintenance and update of the
existing Institute web site with
the aim to have a permanent
forum durably hosting information
on European research activities
related to Grid systems, tools,
and environments, where the
annual workshop will also
be linked in prominently.
• Active participation and support
for the sustainability activities at
CoreGRID level including continuous
collaboration with other CoreGRID
Institutes and constructive contacts
with CoreGRID industrial partners.

The aim of
integration
activities is to
establish durable
mechanisms and

The main objective of the integration activities is to
establish durable mechanisms and infrastructure for
fostering the sustainable integration and re-structuring
of the Network’s research, and to contribute to the
seamless collaboration and dissemination of the work
within the Network of Excellence. Numerous activities
are organised and implemented, which will contribute
to a high degree of sustainable integration between
the partners, with the ultimate goal of overcoming the
current fragmentation of Grid research.
Co-ordination of the
scientific annual roadmap
An annual roadmap has been drawn up
for the six research areas (Institutes)
contributing to the CoreGRID Joint
Research Programme. The Scientific
Annual Roadmap is intended to be
used as a single gateway to the
different Institutes’ roadmaps, including
a high-level scientific positioning of the
whole Network within the context of the
Grid research landscape. The roadmap
is developed in close cooperation
with the Scientific Advisory Board and
Industrial Advisory Board of CoreGRID.
The deliverable produced for the
Scientific Annual Roadmap is
available on the CoreGRID website:
http://www.coregrid.net/Institutes/
This task within the integration
activities provides support to
members willing to participate in
projects or programmes partially
funded by national, bilateral or
multilateral agencies, leading to
better integration. The Network
identified among its members the
suitable contact points to collect
information on national Grid
initiatives that could generate project
proposals. The same activity was
conducted at the European level by
the project co-ordinator. Funding
sources have been identified and
described on a private website. So
far, several research and development
projects initiated by CoreGRID
partners have been accepted and
funded by the European commission:
GridComp, SelfMan, XtreemOS,
EchoGrid, Grid test and Bridge.
Internal collaboration
and dissemination
The CoreGRID internal collaboration
and dissemination is managed through
a dedicated collaborative tool, namely
the BSCW server regularly maintained
and upgraded by the system manager.
This source of information is obviously
confidential and thus only available
for the Network participants in
order to share data and documents
related to the Network activities. In
addition, it provides the partners with
the latest management documents
and project archives. More than
240 users are registered and share
documents independently of the
specific computer systems they use.
27
Regular integration
workshops
One of the Network’s objectives
has been to set up a regular, highquality workshop for the participants
of CoreGRID from all Institutes. The
CoreGRID Integration Workshop
2006 was held in Krakow, Poland,
on October 19-20, 2006 at the IFJ
PAN, attracting 89 participants. The
best papers were selected by means
of an external reviewing procedure
and were published in a Springer
volume of the CoreGRID series.
The final CoreGRID Integration
Workshop 2008 took place in
Heraklion, Crete, Greece, on April
2-4, 2008, hosted by the Institute
of Computer Science ICS-FORTH,
Hellas. The programme featured
43 presentations on collaborative
work between CoreGRID partners, of
which 21 were regular papers and
22 were poster presentations. In
addition, invited talks were given
by Prof. Yannis Ioannidis, Prof. Ewa
Deelman, and Christos Nikolaou.
Sixty-seven participants were
already committed to participate
before the early registration
deadline on February, 15 2008.
As in previous years, the workshop
proceedings will be published at the
beginning of the workshop. The next
step will be the second review of the
best papers which will be published
in the final Springer volume.
The figure displays the CoreGRID
Institutes arranged on a circle,

workshop in cooperation by several
partners as lines between them.
Grid testbeds
The CoreGRID testbed activities aim
at providing researchers with support
to access Grid testbeds maintained
and operated in collaboration with
CoreGRID partners. The database
storing information on experience,
policies and best-practice reports
includes data about testbeds both
on national and European level,
which are available for CoreGRID

researchers. In addition to the Dutch
DAS and the French Grid 5000, the
researchers can now access the Polish
CLUSTERIX, the German VIOLA and
the European PHOSPHORUS testbed,
as well as all experiments made
using these testbeds. A number of
successful experiments have been
conducted using resources of the
DAS and Grid’5000 jointly. Experience
reports can be downloaded from the
testbed web pages on the private
collaborative tool at https://bscw.
ercim.org/bscw/bscw.cgi/62053
The figure above displays the
current topology of the optical
network connections related to the
European PHOSPHORUS project.
Moreover, a grid testbed based on
Globus Toolkit 4 and UNICORE 6
was installed on top of this optical
network. Several CoreGRID partners
contribute to the PHOSPHOROUS
project and the testbed, which
is thus open for CoreGRID
experiments. These experiments
especially contributed towards the
QoS of the underlying network.
Common understanding
of trust and security
The Trust and Security activity
in CoreGRID runs as a horizontal
integration activity related to all the
research areas studied within the
Network. It ensures that the Network
participants are aware of the use
of trust and security technologies
in modern grid environments. Each
CoreGRID Institute includes research
groups focusing on integration work
in this area. In 2007, this activity
organised Grid-STP 2007, the First
International Workshop on Security,
Trust and Privacy in Grid Systems.
Other results are expected through the
participation in the CoreGRID mobility
programme (Fellowship Programme
and Research Exchange Programme)
targeted specifically at Grid security.
Another important outcome results from
the joint CoreGRID white paper on the
current state of the art of Grid security.
In addition, numerous CoreGRID
technical reports, presentations
at international conferences and
publication in journals on this topic
were gathered. Central to this activity
is the Internet-based CoreGRID Trust
and Security Portal, which serves as
a communication forum on Grid trust
and security and provides information
about tools, projects, research groups,
publications and events. As a way of
illustration, the figure on the left shows
a fragment of the security requirements
for a Grid data management system
using the KAOS goal-oriented
requirements-engineering methodology
(spin-off FP6 project GridTrust).

▼
In order to increase the level of integration and to
implement collaborative research the CoreGRID
Network of Excellence is running and managing a
Fellowship Programme open to candidates from all
over the world and a Research Exchange Programme
dedicated to visits among CoreGRID members.
CoreGRID Fellowship
Programme (FP)
The CoreGRID Fellowship Programme
is definitely a great opportunity for
postgraduate researchers to work
collectively on challenging problems as
Fellows of leading European research
institutions. This Programme helps
widen and intensify the network of
personal relations and understanding
among scientists. In addition, the
Programme encourages mobility among
research groups working in similar
areas but in different laboratories.
By driving cooperation, Fellows
help create a strong and durable
integration of Grid research expertise
in Europe towards scientific and
technological excellence.
Since the 1st Call of this Programme
launched on November 15, 2004,
a total of 80 applications have
been received and reviewed by the
Executive Committee. The 4th Call
launched in March 2006 is still open.
Nineteen young researchers were
selected and hosted by one or two
research facilities for two distinct
In the course of the Programme, the
Fellows closely interact with major
researchers and leading scientific
communities. They participate in
regular in-house discussions and
seminars and contribute to the
CoreGRID effort to integrate scientific
activities and dissemination across
Europe. In addition to the training
activities, the Fellowship Programme
promotes career development, ideally
within the Network to preserve
excellence in the research environment.
Throughout and on completion
of the Fellowship Programme, the
CoreGRID Network provides support
and guidance to the Fellow in
his/her effort to obtain a position
in related research activities.
CoreGRID Industrial
Mobility Programme
Besides the integration inside the
Network, CoreGRID opened its
Mobility Programme to industrial
companies. The call was launched
during the First CoreGRID Industrial
Conference held in SophiaAntipolis on December 1, 2006.
29
Annual
Report
2007
Four programmes involving one
to two CoreGRID institutes and
one industrial company have been
selected and granted by the Network.
In the Industrial Fellowship
Programme, Fellows spend time
at a CoreGRID partner’s institution
and at one of the CoreGRID
Industrial Advisory Board members’
offices. This Programme aims at
stimulating knowledge transfer
and reinforcing CoreGRID’s
commitment to taking Grids out of
the research labs into industry.
During the EC review, the external
participants involved in the
Fellowship Programme participated
in the meeting, giving excellent
presentations and providing direct
feedback of their experiences.
CoreGRID
Research Exchange
Programme (REP)
The second part of the CoreGRID
mobility activities is the Research
Exchange Programme (REP), which
allows researchers working in one
of the CoreGRID Institutes to visit
another Institute for durations from
four weeks to six months. This
Programme is also open to students
participating in co-PhD supervision in
order to get a joint degree from two
universities, and to a non-CoreGRID
partner willing to visit a CoreGRID
member. Obviously the purpose of
the visit must be relevant to the
joint programme of activities.
Since the start of the project, 22
Research Exchange Programme
applications have been submitted
to and approved by the Executive
Committee. To date, 18 CoreGRID
Partners have benefitted
from this Programme for an
average stay of 10 weeks.
Results of the Mobility
Programme (2006-2007)
Institutes
Conclusion
The Industrial Fellowship Programme
is considered as a very positive
initiative. The CoreGRID Network
of Excellence invests 12% of its
budget in this activity (€950,000)
to increase partners’ integration in
the European Grid landscape. So far
28 out of the 41 CoreGRID partners
have taken advantage of this Mobility
Programme. It represents 70% of
the partners’ Network. This result
demonstrates that it is an essential
tool for a Network of this size in order
to facilitate partners’ exchange.
The new orientation of the Mobility
Programme towards industry is
one of the project assets for future
research opportunities, as well as
future potential funding opportunities.
Encouraging these exchanges should
guarantee long-lasting relations and
links with industry, essential assets
for ensuring the sustainability of the
six CoreGRID Research Institutes.

CoreGRID aspires to influence the European Grid
and peer-to-peer research community, thereby
making a true contribution to the economic growth
and wealth of the European ICT industry.
Excelling as a research organisation is
therefore an absolute necessity. But
this can only be achieved if we also
excel at spreading excellence outside
the Network, implementing a set of
activities to disseminate scientific
results and knowledge generated
within the CoreGRID Institutes.
To gain the highest visibility and
raise public participation and
awareness, the CoreGRID Network
has implemented an integrated
programme for spreading excellence
by targeting researchers and
industry-based computer scientists
and leaders. Activities include
dissemination and communication,
liaison with industry, and
scientific dissemination, as well
as training and education.
Major CoreGRID “Spreading Excellence”
achievements in 2007 have been to:
• Establish an Industrial Task
Force in order to tighten
the links with Industry;
• Initiate the Industrial
Fellowship programme;
• Increase activities within
OGF and NESSI;
• Increase public awareness and
visibility through marketing
material (brochure, annual
report) and communication
actions (press campaign);
• Strengthen the benefits for
researchers to belong to CoreGRID,
thanks to an active and appropriate
internal network communication
policy, as well as internal workshops.
In 2007, the public website www.
coregrid.eu (also found at www.
coregrid.net) has continued to
increase its visibility within the
Grid research community. The
CoreGRID public website is an
essential means of presenting the
Network to the international Grid
community as a unified Europeanwide research laboratory. The
site not only communicates Grid
research information to the CoreGRID
network, but also to the overall ICT
research community and industry.
Website visibility has increased to an
average of 11,100 unique visitors per
month, coming from all parts of the
world. www.coregrid.eu still appears
in first position when searching
Google for “Grid European research”.
The Google PageRank index remains
at 8/10. (PageRank is a method of
determining a page relevance or
importance and is a good means
to benchmark website visibility).

reports on the life of the Network,
events, partners, major results and
job openings. It also intends to give
visibility to all CoreGRID members
(three of them are presented in each
issue) and serves as a communication
channel for other EU-funded Sixth
Framework Programme Grid projects.
This strengthens collaboration
between Grid R&D initiatives and
between academia and industry.

The meeting focused on collaboration
opportunities between IAB members
and CoreGRID Institutes. Starting
from CoreGRID fellows’ technical
presentations, interactive roundtable
sessions were organised per
Institute, leading to the definition of
collaborative research projects and
to Industrial Fellowship proposals.
In 2007, four programmes have
started on the following subjects:
The Industrial Fellowship
Programme (IFP)
- SLA for supporting use of licensed
software in Grid environments
- Comparative Study over Efficient
Data Transport Protocols in Grids
- Data Management for HighPerformance Distributed
Multimedia Content Analysis
- SLA & Contract Negotiation

The Open Grid
Forum (OGF)
The CoreGRID Fellowship Programme
has been extended to involve industrial
companies. According to the updated
rules, fellows are invited to spend from
12 to 18 months in one or two of the
CoreGRID institutions, out of which
two to six months must be within the
premises of an industrial partner.
The training programme of the fellow
is defined in close cooperation
between the CoreGRID member and
the industrial company. The industrial
company is co-funding the programme.
CoreGRID is a silver organisational
member of the Open Grid Forum (OGF).
The Network sponsored OGF Fellows
and numerous Network members
participated in the OGF 20 in Manchester
in May 2007. The key objective of OGF
being to share technological advances
between enterprises and scientists,
thereby promoting the broad adoption
of Grid technology, it is important for
CoreGRID to take part in such an event
and to demonstrate the quality of its
research activities involving industrials.
Liaison with industry
is an objective that
is spread through
the whole CoreGRID
network, involving
every research team.
Within the frame of OGF20, CoreGRID
organised a Workshop entitled
“Evolutions of GRIDs Towards Service
Oriented Knowledge Utilities (SOKUs)”,
moderated by IAB members and
CoreGRID partners. This Workshop
was intended to initiate a technical
discussion about the SOKU vision
allowing exchange of individual
views on this transition from
key stakeholders represented by
leaders in industry and science.
The workshop was very well attended
with more than 50 participants
(actually limited by the capacity of
the room). This showed the interest
in the particular topic of SOKUs as
part of the European Grid strategy.
The workshop facilitated several vivid
discussions and interaction with the
audience. It became clear that the
SOKU vision includes several aspects
and perspectives and not a singular
vision. The presentations showed many
different facets from standardisation
activities, several existing projects,
and the expectations from commercial
stakeholders as well as the vision of the
European Commission as implemented
in the current work programmes. Overall,
there is a clear trend of convergence
between Grids, service economies,
different application scenarios either in
commercial or scientific environments.

Networked European
Software & Services
Initiative (NESSI)
In September 2005, NESSI was set up
by thirteen European ICT industries
as an ICT European Technology
Platform. NESSI is a major European
industry initiative which aims at
driving innovation throughout the
software and IT services sector.
The NESSI mission is to develop a
visionary strategy for software and
services driven by a common European
research agenda, where innovation and
business strength are reinforced by:
- providing European industry
and the public sector with
efficient services and software
infrastructures to improve flexibility,
interoperability and quality
- mastering complex software
systems and their provision
as service-oriented utilities
- establishing the technological basis,
the strategies and deployment
policies to speed up the dynamics
of the services eco-system
CoreGRID Institutes are collaborating
with NESSI and several NESSI working
groups, specifically about Service
Oriented Infrastructure, Software
Engineering and Trust, Security
and Dependability. This resulted in
contributions to the NESSI Strategic
Research Agenda and in several
CoreGRID members partnering with
NESSI enterprises in setting up winning
FP7 NESSI Strategic Projects (S-Cube,
SOA4ALL, SLA@SOI, RESERVOIR, etc.).
Member survey on
Industrial links
In order to assess the level of
collaboration between CoreGRID
partners and industry, a questionnaire
was sent to the NoE partners in early
August 2007. The objective was to
gather homogeneous input in order to
build a panoramic view of CoreGRID
relationships with industry. Answers
were also expected to reveal to
which extent the Network had been
instrumental in encouraging and
facilitating these industrial links.
The survey revealed that over
93% of the CoreGRID members
have active links with industrial
partners and that 86% are claiming
that CoreGRID was instrumental
in initiating or improving their
relationship with the business world.
Beyond the many interesting
perspectives that this survey provides
to CoreGRID, the most interesting and
rewarding finding is the fact that a
large majority of the members could
lean upon the CoreGRID Network of
Excellence to initiate or develop fruitful
relationships with industrial partners.
In that sense, the survey brings a clear
confirmation that CoreGRID played
its role in connecting its members
with industry at local, national,
European and international level.
Perspectives
During its third year of activity, CoreGRID
has not only succeeded in integrating
and coordinating the European Research
community in Grid technologies, but also
in connecting the academic research
institutes to industry in order to fully
realise the objective of boosting the EU
ICT Industrial sector through bringing
research and innovation to business.

1. Technical synergies
The CoreGRID Collaboration Gateway bundles
major activities aiming at collaboration with other
Grid-related projects of the seventh framework
programme. The activities in the Collaboration Gateway are organised in seven sub-tasks, which are
led by different CoreGRID partners:
Based on the foci of research and
development of the different European
Grid-related projects, a number of
areas have been identified for crossproject technical co-ordination and the
following eight technical groups (TG)
have been set up and are working:
1 Exploitation of synergies and
technical co-ordination (leader INRIA)
2 Joint fora for exchange and
dissemination (leader CETIC)
3 Co-ordination of standardisation
efforts (leader FHG)
4 Repository of reference
implementations and Grid
middleware (leader FHG)
5 Collaboration on roadmaps
(leader FHG)
6 Training activities (leader UPC)
7 Collaboration with NESSI
platform (leader CETIC)
When taking a closer look at the
European Grid projects of the sixth
framework programme it became
obvious at an early stage that despite
all differences of the projects’ focus
areas, each one tends to implement a
small set of similar tasks, e.g. related
to dissemination, standardisation,
software repositories, or training. In
particular, the larger type of projects
(Integrated Project (IP) and Network
of Excellence (NoE)) put substantial
effort into these activities. Thus, the
idea of making resources and results
available to other projects is quite
natural and was already implemented
early in the sixth framework
TG1 Grid Architecture, TG2 Ontologies,
TG3 Workflows, TG4 Monitoring
and Fabric Management, TG5 Data
Management, TG6 Trust & Security,
TG7 Grid Economics and Business
Models, TG8 Virtual Organisations.
The TGs published yearly white papers
on related research and development
to identify gaps that should be
addressed in future projects and
possible synergies arising from the
collaboration. In addition to the annual
co-ordination events, the TGs organise
an additional annual meeting for the
presentation and discussion of the
groups’ results and the structuring of
the work for the following period.
2. Joint fora for
exchange and
dissemination
IPs and NoEs are strong at
disseminating their results and have
the necessary resources to do so. This
task aims at identifying and using joint
fora for exchange and dissemination
of project results. There are several
39
clear benefits in co-ordinating the
dissemination activities. Larger
audiences are reached by using the
different channels established by the
projects. Joint events usually attract
more participants. Small projects
with limited resources may hook up
and use the channels and events
maintained by the bigger projects.
Finally, these may be achieved without
significantly increasing the effort in the
individual projects. One example is the
CoreGRID newsletter, which is open to
contributions from other projects as
well. CoreGRID also submits articles on
research activities and results in other
projects newsletter, etc. Additionally,
CoreGRID started in 2007 organising
the CoreGRID Symposium, which
aims to become the largest European
conference focussing on Grid research.
3. Co-ordination of
standardisation efforts
Many European projects are relying on
existing or evolving Grid standards.
A number of them are actually also
contributing to the development of
standards in different standardisation
bodies while other projects have
identified requirements for standards
that are not yet addressed. The number
of European co-chairs and participants
of the research and working groups
of the Open Grid Forum has increased
significantly over the last several years
as a direct result of this activity. To
strengthen the European impact in the
standardisation process, the projects
collaborate in the Grid Standards
Co-ordination Group (GSCG) where
each project is represented. The GSCG
holds regular face-to-face meetings
and teleconferences and has produced
a white paper. The white paper
describes the standards activities of
the projects, standards requirements,
and bodies where project members
are already active. It also identifies
the bodies to which further standards
activities should be directed.
4. Repository
of reference
implementations and
grid middleware
Within this task, CoreGRID is focussing
on creating and maintaining the
“CoreGRID Repository of reference
implementations and Grid middleware”
to be filled with Grid-related
developments by CoreGRID partners
over time. A Quality Assurance
Group (QAG) has been set up, which
has defined the process to follow
to ensure uploads of high-quality
Grid software components. Each
CoreGRID Institute has appointed a
representative for the QAG acting as
a contact point for institute members
willing to contribute Grid software. The
folder hierarchy follows the research
areas of the CoreGRID institutes
and the technical groups. Moreover,
the repository will provide links to
repositories maintained by other
projects or initiatives. The BEinGRID
project has agreed to maintain a
software repository on a European
level. The CoreGRID repository will
be cross-linked with the BEinGRID
one to allow easy access to European
software developments without
duplicating the management effort.
5. Collaboration
on roadmaps
Based on the annual roadmaps created
by the CoreGRID Institutes and with
additional contributions from the other
Grid-related projects, this collaboration
activity has produced a first version
of a European Grid Roadmap, which
was prepared by representatives
from all projects in the European Grid
Roadmap Group (EGRG). The EGRG is
responsible for gathering information
from all projects relevant to the
European Grid Roadmap, including
project focus, planned developments,
timelines, etc. The structure of the
roadmap document follows the
thematic grouping of the CoreGRID
institutes complemented by the topics
of the Technical Groups that have no
corresponding CoreGRID institutes.
The European Grid Roadmap is
currently being updated incorporating
contributions from several sources:
(i) the current version of the annual
roadmaps of the CoreGRID Institutes,
(ii) achievements made in the other
projects, (iii) results from the Technical
Groups, and (iv) contributions from
new projects that have been launched
since the last publication of the
roadmap document. The updated
version includes an overview of
the research and developments
planned or made in the different
projects and a SWOT analysis. The
document is available in the CoreGRID
repository (http://www.coregrid.
net/mambo/content/view/58/79/).
6. Training activities
The goal of this collaboration task
is to co-ordinate training activities
organised by different projects and to
define a training activities roadmap at
the European level. This allows better
use of the resources and ensures that
smaller projects (STREPs) benefit from
the training organised by the larger
ones. The group cross-disseminates
the training activities through mail and
via the collaboration website. It is also
participating in the training activities
of the Open Grid Forum. In addition,
the group jointly organises some
training events, e.g. the CoreGRID
summer school with Summer School
2007 in Budapest, where several
projects contributed to the programme.
The training material is also made
available through the CoreGRID
repository and the ICEAGE repository.
7. Collaboration
with NESSI
The objectives of this task are to
allow all Grid projects to be aware
of the evolution of the NESSI Vision
and versions of the Strategic Research
Agenda. Also, it should promote the
participation in specific working groups
on research topics of the platform.
Significant impact on the alignment
of the projects’ R&D is expected, as
NESSI is the Networked European
Software and Services Initiative
European Technology Platform aiming
to provide a unified vision and
strategic research agenda for European
research in Software and Services by
establishing the technological basis
and developing strategies that will
speed up Europe’s transition to a
knowledge-based economy through
service-oriented business models.
After a couple of years of experience
with the European concertation
activities, it may be concluded that
CoreGRID achieved a substantial
impact as briefly detailed in
the previous paragraphs.
CoreGRID is one of the largest
European Network of Excellence
with 46 partners from 19 countries,
a NESSI partner, a sponsor of the
Open Grid Forum. CoreGRID has a
leading position in the European
Grid research and Grid expertise.

Financial
resources overview and
breakdown
The first three years of the Network
proved that CoreGRID satisfied
most of the researchers’ needs. The
opportunity offered to the Network
of Excellence (funded under the
Sixth Framework Programme) to
fund part of the manpower has had
a strong impact on the researchers’
integration. The budget flexibility
given by the European Commission
has allowed important changes in
financial allocations to the six major
activities. Network membership has
finally been able to evolve according
to partners’ needs and participation.
Budget
The CoreGRID Network of Excellence
is the only network funded by the
European Commission’s Service and
Software Architectures, Infrastructure
and Engineering Unit. The CoreGRID
budget allocated by the European
Commission amounts to a maximum
of €8.2 million. This grant will be
distributed over a period of four years
among the 41 partners, depending on
their activity and commitment levels.
Until now, the Members’
General Assembly has agreed
to use the European budget to
fund six major activities:
•
•
•
•
•
Administrative co-ordination
Scientific co-ordination
Integration activities
Spreading Excellence
JPA (Joint Programme of
Activities) Grant to Scientists
• Various activities
It has to be emphasised that the
project is only partially funded by
the European Commission. The total
estimated costs for the full duration
of the project were evaluated at
more than €19 million, while the EC
funding will not exceed €8.2 million.
Detailed
breakdown
among activities
The budget for CoreGRID activities
was agreed upon by the consortium
before the start of the project, and
financial plans for 12, 18 and 48
months have been established. The
budget distribution is not frozen
and was adjusted to match the
Network’s evolution and needs. In
particular the four-year plan has
been established as follows:
Administrative and scientific coordination costs correspond to 18%
of the overall budget. These include:
• part of the salaries and travel
costs for the administrative
and scientific teams;
• a lump sum allocated to
the Workpackage leaders,
IMC and MGA Chairmen;
• a system manager and provision
of collaborative tools; and
audit certificates costs.
Integration and Spreading of Excellence
activities are allocated an estimated
budget of €1.86 million (representing
22% of the overall budget) and
include the following activities:
• a research exchange programme
to encourage internal shortterm mobility (2%);
• a fellowship programme to
attract bright young scientists for
eighteen-month periods (9%);
• publishing and dissemination
activities (annual summer
schools, annual report) (8%);
• annual integration workshops;
and sustainability (WP1 transversal
activity) + SOA-related tasks.

Third year
activities
The grant to scientists distributed to
the CoreGRID partners represents 59%
of the entire budget. This allocation is
based on the number of researchers
involved in each institute and each
activity. The involvement of the
partners evolves in accordance with
the Network’s needs as discussed at
the annual meetings of the Scientific
and Industrial Advisory Boards.
All Network activities are fully
operational since the beginning of year
two. In year three, the expenditure
linked to Network coordination and
to various activities remained stable.
Meanwhile the Spreading of Excellence
budget has been regularly increased
to support the Network’s efforts in
disseminating its results (summer
schools, integration workshops and
industrial conferences). The most
successful activity during this 3rd year
has been the mobility program; 70%
of the Network partners benefited
from this programme. Nineteen fellows
were recruited all over the world and
22 visits were organised between
Partners and/or Associate Partners.
The total expenditure for the entire
network duration (48 months) has
been refined according to the real
costs submitted during the first
three years of activity and to the
planned budget for the last year.
CoreGRID
Global Budget
This distribution has been mapped
to the Network’s actual activities.
The budget is divided into six fixed
sections (see “detailed breakdown
among activities”) so that a
comparative analysis can be performed
with the previous years’ figures. The
main part of the budget is dedicated to
research and dissemination activities.
These budgets made possible
the organisation of high quality
conferences and events which are key
factors for the successful integration
of our 41 partners. In addition, the
mobility programme was adapted to
support joint collaboration between
CoreGRID partners and Industry; a
tool which proved very efficient in
improving the transfer of results
from our research institutes towards
industry. Closely interacting with
industry is a key asset of the project,
from which future research and
potential funding opportunities may
result. The consortium will investigate
all future opportunities while preparing
its final sustainability plan.
Despite the complexity of the Network
of Excellence regulations, the budget
allocated by the Commission in 2004
will be fully used by the end of the
project and all activities foreseen
and added during the project lifetime
will be completed. This is the result
of a strong partnership and of
efficient project management.

research arena.
• Organisation of 59 meetings and 17
workshops, contributing to solving
research challenges as described in
the CoreGRID research roadmaps.
▼
After three years of existence, CoreGRID has carved out a place for itself in the international Grid
research arena. It has become one of the largest
research centres in Grid computing, encompassing
a vast range of research topics such as knowledge
and data management, programming models, middleware, resource management and scheduling,
workflow, service infrastructures and P2P systems,
just to cite a few. It has reached its ideal objective:
to become the European Grid beacon. The third
year is the right time to list all the achievements
accomplished by the network and not only the activities performed in 2007.
• Delivery of more than 447 joint
technical papers accepted in peerreviewed conferences, workshops
and journals, including six highly
reputed CoreGRID series volumes,
thus advancing European excellence.
• Publication of 122 CoreGRID
technical reports, co-authored by at
least two different CoreGRID partners
showing the level of integration
among the CoreGRID community.
• The effective kick-off of several
spin-off research projects, funded
either by the European Commission
within the 6th and the 7th
Framework Programmes, or through
national and/or regional initiatives

peer-to-peer computing with around
1,050 references available today.
• Increased visibility of the Grid
research community through
the support of highly-reputed
international conferences, such
as EuroPar 2005, 2006 and 2007,
HPDC 2006, IEEE conference on
Grid Computing in 2006 and 2007
and events such as Grid@Work
2006 and 2007. CoreGRID also
sponsored the Open Grid Forum.
• Opening up academic research
agendas in order to identify
business-oriented research
priorities, leading to the spinoff of new CoreGRID activities,
for example in service-oriented
architectures and systems.
• Developing new ideas to anticipate
technological trends and to
promote commercially relevant
and promising research.
• Active involvement of industrial
stakeholders to help identify takeup opportunities beyond publicly
funded programmes, thus stimulating
the investment of industrial
stakeholders in CoreGRID institutes.
• Setting up a Grid User Community
in order to raise public awareness.
• Organisation of several scientific
workshops jointly with highly
reputed international conferences
and the CoreGRID symposium
jointly held with EuroPar 2007.
• Organisation of three annual
CoreGRID Summer Schools.
• Implementing Mobility Programmes
- a Fellowship Programme and a
Researcher Exchange Programme
- increasing integration between
partners, and now involving
industrial members of the IAB.
• Organisation of three annual
Integration Workshops.
During the fourth year, the Network
is committed to implementing its
sustainability plan. This is more than a
commitment; it is also an enthusiastic
determination from all participants
to continue to work together and
address new research challenges.
The idea to set up CoreGRID came in
2002 and since that date, computing
technologies have evolved and Grid
is merging with some prominent
concepts such as Service and Cloud
computing. But the initial idea remains
the same and our vision is still valid:
how to set up a fully distributed,
dynamically reconfigurable, scalable
and autonomous infrastructure
to provide location independent,
pervasive, reliable, secure and
efficient access to a coordinated set of
services encapsulating and virtualising
resources (computing power, storage,
instruments, data, etc.) in order to
generate knowledge. Grid computing
has paved the way towards new
computing systems that consider the
Internet as a computing infrastructure
per se. The Grid research community
can be proud of what it did over the
last ten years: it has shown that a
large scale distributed computing
infrastructure can be implemented and
deployed over the Internet to support
the execution of e-Science applications
and to serve a wide spectrum of users,
thereby answering their needs for
advances in their own research field.
CoreGRID will play an important
role in the transition from Grid to
Service computing. It already features
a set of activities targeting service
infrastructures, in particular in the
area of Trust & Security, Service Level
Agreement and Middleware Systems.
CoreGRID has also acquired valuable
expertise in coordinating a research
community. CoreGRID will evolve from
a Network of Excellence towards an
ERCIM working group covering both
Grid and Service computing. It will
act in a complementary way with
other projects such as the S-Cube
Network of Excellence in which several
CoreGRID partners are involved.
This Working Group is being set up
and will be operational by 2008 in
order to ensure a smooth transition
between the EC-funded NoE and the
self-sustained WG, while maintaining
the momentum of the European
collaboration on GRID research.
