6CoreGRIDNetworkCoreGRID is helpingEurope to take Gridsout of research labsand into industry.of ExcellenceFour Years of CoreGRID AchievementsCoreGRID -conceptThe CoreGRID Network is funded bythe European Commission within theEuropean Union’s Sixth FrameworkProgramme for research andtechnological development. A grant of€8.2 million has been assigned to theproject for a duration of four years.CoreGRID comes under the frameworkof Europe’s Information SocietyTechnologies (IST) thematic priority.IST has defined Grid technologiesas a crucial objective that willtransform the European Union intothe most competitive knowledgebasedeconomy in the world.By providing everyone withimmense computing power andknowledge – currently unavailableto even the largest corporations andlaboratories – Grids will improvethe competitiveness of Europeanindustries and mark a new era ofmarkets and services previouslyperceived as impossible to driveforward. The impact on our quality oflife will be profound, allowing us tobetter monitor and model everythingfrom global climate change to theway cars behave in collisions.In order to put Europe in front andmake sure today’s research addressestomorrow’s market needs, CoreGRIDis committed to structuring Europeanresearch by integrating a critical massof expertise and promoting scientificand technological excellence within andbeyond the Grid research community.Through this commitment, CoreGRIDis helping Europe to take Grids outof research labs and into industry.This initiative marks a critical stepin ensuring that Europe realises thebenefits of the information society.CoreGRID -objectives &structureLaunched on September 1, 2004, theCoreGRID initiative aims at buildinga virtual Europe-wide researchlaboratory that will achieve scientificand technological excellence in thedomain of large-scale, distributedGrid and peer-to-peer technologies.The primary objective of theCoreGRID Network of Excellence isto build solid methodological andtechnological foundations for Gridand peer-to-peer, and to stay at theforefront of scientific excellence.This objective will be achievedby structuring integrated researchactivities carried out by experts inparallel and distributed systems,middleware, programming models,algorithms, tools and environments.This joint research will contribute torealising the CoreGRID vision of afuture Grid infrastructure: seamlessintegration of the existing Grid andother emerging architectures (suchas peer-to-peer) using conceptsand standards from the WorldWide Web Consortium and otherrelevant standardisation bodies.To comply with this long-termobjective, the CoreGRID Networkruns a joint programme of activities(JPA). The JPA integrates andco-ordinates the activities of themajor European research teamsin the field of Grid and peer-topeertechnologies. Composed ofwell-established researchers (161permanent researchers and 164 PhDstudents) from 46 research centresand universities, the CoreGRIDresearch teams bring high-levelexpertise in specific areas. They alsoinfluence their national Grid andpeer-to-peer programmes, fosteringbetter long-term integration.

14CoreGRIDInstitutesThe general goal is tofurther integrate datamanagement andknowledge discoverysolutions with Gridtechnologies.Domenico TaliaLeader of the Knowledge and DataManagement Institute, Università dellaCalabriaKNOWLEDGE ANDDATA MANAGEMENT▼Grids are changing their role, moving from acomputation and data management platform to apervasive information and knowledge managementinfrastructure. This trend requires new models,services and technologies for enabling Gridcomputing systems to manage distributed dataand knowledge, enabling complex applicationsaccording to the SOKU model.The INSTITUTE ON KNOWLEDGE AND DATAMANAGEMENT (KDM) joins together thirteeninstitutions from eight European countries andinvolves more than 50 senior researchers and PhDstudents. The general goal of this Institute is tofurther integrate data management and knowledgediscovery solutions with Grid technologies forproviding data- and knowledge-intensive Grids.The Institute provides a collaborativesetting for European researchteams working on: distributedstorage management on Grids;knowledge techniques and toolsfor data-intensive applications;security and trust mechanisms forstorage and data; and integrationof data and computation Grids withinformation and knowledge Grids.The goal of the second year hasbeen to consolidate and expandthe joint activity of research groups,thus promoting larger leadingteams and supporting effortstowards standard models, services,middleware and solutions.During the third year, the Institutemembers (CETIC, FORTH, CNR-ICAR,INFN, CNR-ISTI, PSNC, STFC-RAL,SZTAKI, Universidade Nova de Lisboa,University of Calabria, University ofCyprus, University of Manchester,and University of Newcastle)worked on three main tasks:1 DISTRIBUTED STORAGEMANAGEMENTProviding infrastructures, techniquesand policies for managing distributedstorage resources in the Grid.2 INFORMATION AND KNOWLEDGEMANAGEMENTDeveloping metadata, semanticrepresentation and protocols forGrid service discovery, informationmanagement and design ofknowledge-oriented Grid services.3 DATA MINING AND KNOWLEDGEDISCOVERYDesigning Grid services for distributeddata mining and knowledge discoveryon Grids and P2P systems.In all those areas in 2007 the partnersjointly produced scientific resultsimplemented in software prototypesand published in scientific journalsand conference proceedings.

➦Data Mining and Knowledge DiscoveryKDM➦Distributed Storage Management15AnnualReport2007Information and Knowledge Management➦Additionally, security issues havebeen covered with a particular focuson security requirements and modelsfor storage and data management.ObjectivesThe main objective of the KDM Instituteis to address issues like representation,discovery and integration of data andknowledge in Grids and P2P systems.The Institute’s approach is a verticalapproach that encompasses all layersinvolved with knowledge managementin Grids: storage managementat the systems-level, informationand knowledge management, andknowledge discovery. At the sametime, single KDM solutions that bringbenefits to the Grid community havebeen designed and developed.A key KDM objective is to designand develop common solutions fordata management and knowledgediscovery and management on Grids.This promotes the wide diffusionand use of knowledge-based Gridservices for the Semantic Grid andthe Knowledge Grid. To this end,the partners of the KDM Institutefocus on the problems of providingcommodity-based connectivity amongheterogeneous distributed storagedevices, management automationof administration tasks traditionallyhandled manually, and storagevirtualisation for serving well-definedrequirements from multiple users.Another challenge we investigatedis the need to develop autonomoussecurity mechanisms for decentraliseddata management involving selforganisingbehaviour. Finally, significantresults have been achieved in topicssuch as data federation, integrationand querying, dynamic workflowexecution, Grid-aware knowledgediscovery, and P2P data management.As a result of the joint activities, newresearch results, software prototypesand system solutions have beendeveloped in such areas as storagemanagement, distributed dataintegration, reliable dynamic queryprocessing, storage security models,knowledge discovery services, Gridontology, and P2P data management.We organised Institute meetings andworkshops jointly with other CoreGRIDInstitutes, exchanged visits, set up jointfellowships, and produced two books,as well as tens of publications andtechnical reports. We organised jointresearch activities for research groupsworking on the main KDM topics. Jointactivities are carried out with otherCoreGRID Institutes on scheduling fordata Grids, self-configuring storage,scalable Grid services, resourcediscovery, and P2P Grids. We alsocontributed to the EC TechnicalGroup 5 on Data Management.Industryadded-valueThe results of the research activitiesof the KDM Institute can be exploitedby European industries workingin the area of data managementand knowledge services. Researchactivities in the area of data Grids andknowledge Grids are being pursuedby many industries such as HITACHI,Microsoft, IBM, SAP, ORACLE, andSIEMENS. This is testimony to theindustrial relevance of KDM topics.KDM Institute partners started newnational and European joint projectsin KDM research areas. CoreGRIDpartners submitted together withindustrial partners project proposalsfor building knowledge and datamanagement solutions made largelyusable through Grid services. Securityand service level agreement issues arealso investigated. Institute partnersworked with IAB member companieson proposing CoreGRID fellowshipsin KDM areas of industrial interest.Challenges andperspectivesDeveloping knowledge-basedapplications that exploit Grid featuresto achieve high performance andhigh availability is an area of activeresearch in Europe and overseas.Industry is also very active inexploring and adopting new solutions.CoreGRID KDM researchers willwork towards providing a variety ofmodels, architectures, prototypes,and services offering differenttechnological solutions to currentproblems faced by Grid applications.Future research activities will focuson core technologies needed forimplementing the SOKU model,including ontologies, data miningand knowledge discovery, anddata management, also takinginto account SLAs. Partners ofthe KDM Institute will proceedbeyond the funded period and willcontinue their joint activities.

16CoreGRIDInstitutesComponentsand services arebecoming evercloser and commonperspectives maybe exploited.Marco DaneluttoLeader of the Programming Model Institute,Università di PisaPROGRAMMING MODEL▼Programming Model Institute: making the programmingof Grid infrastructures as simple, transparentand efficient as possible.While Grid tool technology is rapidlyconverging towards Services andService Oriented Architectures,advanced programming environmentsare still needed that may simplifythe Grid programmer’s task andshorten the application design-toproductiontime while outperformingapplications written using plain,low-level Grid middleware tools.The Programming Model Instituteaims to investigate new ProgrammingModels capable of fully supportingefficient Grid programming, andto raise the level of abstractionprovided to the Grid applicationprogrammer as recommended inthe NGG documents.The Programming Model Institutebrings together 13 full partnersand 2 associate partners, with atotal of more that 45 researchersand about 30 PhD students.Altogether, these researchershave contributed to an extensiveprogramme of short visits, to theresearcher exchange programme,to CoreGRID fellowships ofteninvolving other CoreGRID Institutes,and have published a significantnumber of joint research papersin international journals andpresented them at conferences.The Programming Model Instituteinvestigates suitable Grid programmingmodels and techniques based oncomponent technology. Componentsand services are becoming evercloser and common perspectivesmay be exploited in the designof advanced component-basedprogramming frameworks supportingfull interoperability with services.Within the Institute, the GCM (GridComponent Model) has been definedand is currently being refined. A spinoffSTREP project has been started(Jun06 – Nov08) whose main goal isthe implementation of an open sourceprototype implementation of GCM.GCM builds on top of the Fractalcomponent model and offers tothe Grid application programmerhierarchical component composition,autonomic controllers, advanced andcollective component communicationpatterns, as well as an XML based ADL.Within the Programming ModelInstitute, ISTI/CNR, HLRS, IC, INRIA,QUB, WWU Muenster, UCHILE, UNI-PASSAU, UNIPI, EIA/FR, UOW, UPC,VUA, UoS and UoL have activelyparticipated in the activities ofthe three main research topicscovered by the Institute: “BasicProgramming Models”, investigatingthe Programming Models suitablefor programming primitive GCMcomponents; “Componentsand hierarchical composition”,investigating the basic features ofGCM; and “Advanced ProgrammingModels”, investigating the possibilityof building advanced ProgrammingModels on top of GCM.In 2007, the activities in theProgramming Model Institute havebeen mainly centred on a couple ofCoreGRID events (the workshop coorganisedby the Architectural Issues:Scalability, Dependability, AdaptabilityInstitute, by the Programming ModelInstitute and by the Grid Systems,Tools and Environments Institute inHeraklion in June; and the CoreGRIDSymposium in Rennes in August)and on a quite large number of

17short visits and Research ExchangeProgramme events involving Instituteresearchers from different partners. Allof the Institute partners participatedin the Heraklion workshop and mostof them also participated in theCoreGRID Symposium, presentingseveral important research resultsand discussing with partners bothexisting and new research topicsin the Institute. Overall, severalnotable results have been achievedin 2007, concerning GCM mechanismand structure refinement andrelated to GCM-based advancedprogramming models and GCMverification/modelling techniques.The advances in Programming ModelInstitute activities contributed to theCoreGRID goal of providing solidmethodological and technologicalfoundations for Grid and peer-to-peer.The GCM model is being adopted andused in several other Institutes withinthe NoE. GCM-related results have beenpresented and appreciated in a numberof international contexts, includingSuperComputing07 and EuroPar07conferences, OGF (Manchester07) andthe CoreGRID Scientific Advisory Board.The results achieved during 2007contributed to the well-focusedobjective of the Programming ModelInstitute that may be summarised asbeing able to deliver a definition of acomponent programming model thatcan be usefully exploited to design,implement and run Grid applicationswhile efficiently and transparentlyfacing the new challenges in termsof programmability, interoperability,code reuse and efficiency that derivefrom the peculiar Grid features suchas heterogeneity and dynamicity.During 2007, partners of theProgramming Model Institute:• Demonstrated autonomicmanagers taking complete careof performance related (nonfunctional)aspects of notablecomposite components.• Refined several formal andsemi-formal techniques thatallow reasoning about GCMprogrammes and proof ofproperties of these programmes.• Achieved further results relatedto the usage of “data sharing”and “data flow stream” portsamong GMC components.• Demonstrated the possibility ofcombining classical parallelisationtechniques (such as looptransformations) with structuredprogramming environments that caneventually be built on top of GCM.• Started to demonstrateinteroperability of GCMconcepts with software servicesand SOA in general.• Finally, during the GRIDS@work event in Beijing (endof October) the preliminaryprototype developed byGridCOMP demonstrated theability to efficiently deploy andrun component programmeson hundreds of distributedGrid resources. This is notdirectly a CoreGRID result,although most GridCOMPpartners are also partners of theProgramming Model Institute.These results have been achieved bypartners of the Institute cooperatingvia all the mechanisms providedby CoreGRID (short visits, REPs,fellowships) and clearly contributeto the Programming Model Instituteobjective. In turn, the main objectivein the Programming Model Institutecontributes to the overall CoreGRIDroadmap both in the field of toolsand environments for efficient Gridprogramming and in the field ofmethodologies for the developmentof suitable Grid software. The GCMis in fact being used as a referencemodel in the Grid Systems, Toolsand Environments Institute. GCM isalso being considered as a suitableprogramming model to developseveral kinds of (system) applicationsin other Institutes in the NoE.Through participation in GridCOMP,several industrial partners havebeen involved in the GCM designand development process. TheProgramming Model Institutebuilds on these experiences insuch a way that the final GCMcould be immediately used intypical industrial applicationswithout any further tuning.Also, a standardisation process hasbeen initiated through ETSI that willeventually result in a complete GCMstandard. In 2007, the first steps havebeen performed and the GCM ADLis close to being an ETSI standard.We expect that Programming ModelInstitute activities, and thoseconcerned with GCM in particular havea twofold impact on industry: on onehand, the availability of a complete,advanced, component-based Gridprogramming environment will allowindustry to cut the development timeand cost of Grid applications. On theother hand, complete interoperabilitywith the services framework (one ofthe objectives of the ProgrammingModel Institute yet to be achieved)will allow industry to reuse andexploit a large base of alreadydeveloped software services in a moreconvenient programming framework.There are still several openchallenges to be tackled in theProgramming Model Institute:• Complete integration of GCM withthe software service framework.Although Institute partners alreadypartially demonstrated the feasibilityof porting GCM concepts on top ofthe Service Component Architecture,much work has to be done toguarantee that the advancedconcepts introduced in GCM (suchas collective communicationpatterns or autonomic managers)can be migrated to thesoftware service scenario.• Implementation of advancedprogramming models on top of GCM.There are several kinds of advancedprogramming models considered tofurther raise the level of abstractionpresented to Grid applicationprogrammes, ranging from skeletonbasedstructured programmingparadigms to component paradigmscombining spatial (componentlike)and temporal (à la workflow)composition of components.• Development of a complete set offormal (or semi-formal) tools that canbe used to reason about and proveproperties of GCM programmes.Partners in the Programming ModelInstitute recognise these are significantchallenges still to be addressed. Duringthe Institute meeting in Heraklion(June) partners also agreed that theactivities needed to tackle thesechallenges must be continued after theend of the NoE, either on a volunteerbasis or within possible furtherinitiatives and projects following the(formal) end of the CoreGRID NoE.AnnualReport2007

18CoreGRIDInstitutesThe Institute aimsto contribute tothe mandatoryarchitecturalprinciples of the NextGeneration Grids.Paraskevi FragopoulouLeader of the Institute on Architectural IssuesFoundation for Research and Technology – HellasInstitute of Computer ScienceFORTH-ICSARCHITECTURAL ISSUES:SCALABILITY, DEPENDABILITY,ADAPTABILITY▼The main goal of the Institute on ArchitecturalIssues (System Architecture - SA) is to provide thetechniques that will pave the way towards scalable,adaptable, and dependable Grid architectures andservices meeting the mandatory properties of theNext Generation Grids.The Institute on Architectural Issues joins togetherthirteen partners from eleven different Europeancountries and involves more than 60 senior researchersand PhD students. During the past year ofthe project, two CoreGRID associated members,CNR-ICAR and the University of Sannio, both fromItaly, joined the SA Institute.The principal goal of the SA Instituteis to perform research on particularaspects of the Grid technologies forproviding basic building blocks forfuture Grid architectures - scalabilityand P2P technologies, dependability;and adaptability/self-management- which meet the mandatory propertiesof Next Generation Grids. The ultimatechallenge is to make the Gridscalable, dependable and adaptableby devising novel mechanisms andproposing improved techniques.The Institute involves thefollowing partners:• FORTH-ICS,Greece• INRIA, France• KTH, Sweden• SICS, Sweden• MTA-SZTAKI,Hungary• UNICAL, Italy• UCO, Portugal• UCY, Cyprus• UCL, Belgium• UoM, UK• UoW, UK• UPC, Spain• ZIB, Germany• CNR-ICAR, Italy• UoS, ItalyThe research activities of the Instituteevolve around the following fivetasks with well-defined objectives:1. P2P-Based Services andResource DiscoveryProviding new solutions forresource location and discoveryon Grid systems based on theP2P paradigm, comprisingtechniques with mobile agents.2. Self-Organising Grid Servicesusing P2P TechnologyDesigning techniques usingcomposition of servicesand semantic planning.3. Dependability Mechanismsfor Computational andData Desktop GridsDeveloping dependabilitymechanisms for scalableGrids comprising two differenttypes of applications andmiddleware: computationalGrids running on public Internetresources (i.e. desktop Grids)and data/service Grids.4. Fault-tolerance and RobustnessStudying the impact of faults ondistributed applications, targetingplatforms such as clusters and Grids.5. Adaptive Management ofSystems and ResourcesDeveloping mechanisms forautomated adaptation andself-management of the Gridson all hierarchy levels.

Each task comprises two to threeresearch groups which constitute thebasic building blocks of the Institute.These tasks define clear-cut objectivesand produce concrete research results.Moreover, the Institute contributestowards the horizontal activity onTrust and Security providing novelrobust mechanisms and techniquessuch as checkpointing and recoverysystems. Last but not least, there isstrong contribution to the recentlyestablished horizontal activity onService Oriented Architectures (SOAs).The scientific interaction between theresearchers of the Institute duringthe third year of the project producedmore than 40 joint research papers,many of them published in well-knowninternational journals and presentedat conferences, while a total of twelveCoreGRID technical reports have beenpublished on the CoreGRID website.One of the publications was selected asbest paper at the 7th IEEE InternationalSymposium on Network Computingand Applications (IEEE NCA08).The workshops and technical meetingsorganised by the SA Institute allowedthe dissemination of the scientificoutput to other CoreGRID Institutes aswell as to external organisations. InFebruary 2007, a special issue of thejournal Future Generation ComputerSystems (FGCS) published selectedpapers. During the third year of theproject the CoreGRID Workshop onGrid Programming Model, Grid and P2PSystems Architecture, Grid Systems,Tools and Environments, took placeJune 12-13, 2007 at FORTH, Heraklion-Crete, Greece. The workshop wasjointly organised by the PM SA and STEInstitutes. A special CoreGRID Springervolume, to appear soon, will includeselected publications of this workshop.ObjectivesThe main objective of the SA Instituteis to significantly improve architecturaldesigns of Next Generation Grids byperforming collaborative research onthe following key architectural aspects:• To apply and extend results fromresearch on peer-to-peer systems forenabling higher scalability and selforganisationof Grid infrastructures.• To investigate the mechanismsfor fault-tolerance and robustnessof the Grid infrastructure toassure reliable Grid services.• To study methods for adaptabilityand self-management in order toestablish paradigms for automaticand low-cost Grid management.To achieve scalability we extend theresults from research on peer-topeersystems and propose scalableapproaches for resource discovery. Wepropose dependability mechanismsfor all levels of the Grid includingcheckpointing and recovery. Wedevise techniques for fault toleranceand robustness for Grid services,providing a more reliable Gridarchitecture. In adaptability and selfmanagement,we develop mechanismsfor automated adaptation andreconfiguration of Grid infrastructure.Through these objectives, the SAInstitute aims to contribute to themandatory architectural principlesof the Next Generation Grids byscalability of services, resilience,straightforward administration andconfiguration management.The scientific highlights of theSA Institute could be brieflysummarised as follows:• The design of a hybrid P2P-basedsystem that works efficiently formulti-attribute queries on staticand dynamic attributes and itsexperimental evaluation on existingGrid platforms (Grid 5000).• The development of dependabilitymechanisms based onvirtualisation techniques thatlead to zero downtime. Theproposed solution is applicableto individual servers, clusters,as well as Grid infrastructures.• Modelling and prediction ofworkloads and system behaviourwith impact to adaptable solutionsfor self-managing systems thatprovides support for scheduling.• Refinement of scalable, dependableand adaptable Grid solutions,and their experimentationof real Grid platforms.• Investigation of the fault conditionsof existing Grid infrastructures (e.g.EGEE) towards the developmentof a framework that will proposeconcrete solutions for low-costautomatic fault managementin Next Generation Grids.The SELFMAN FP6 EU project is aspin-off of CoreGRID involving mainlypartners from the SA Institute andindustrial partners. This project isrelated to the areas of peer-to-peercomputing and adaptability/selfmanagement.This collaborationprovides the SA Institute withreal-world use cases, especially fordependability and self-managingapplications. Other EU spin-offprojects were proposed duringthe last EU call from partners ofthe SA Institute and industry.Industryadded-valueThe IAB members pointed to theP2P paradigm as a useful examplethat could lead to real scalablesolutions in Next Generation Grids,while emphasising the importance ofdependability for high quality serviceprovision and low cost automatedself-management. The remarks of theIAB members provide strong indicationthat currently the research work withinthe SA Institute has the right focuswhile the produced results lead tosolutions of interest to industry.Achievementsand perspectivesSeveral obstacles have to be overcomebefore the objectives of the NextGeneration Grid are achieved. Gridshave to become more robust andpervasive. The challenges faced by theSA Institute for System Architectureconstitute the cornerstone upon whichany Grid middleware should be built.During the CoreGRID project, concretesolutions and major steps have beenmade towards the invisible Grid.The researchers involved in the SAInstitute of CoreGRID are determinedto work together after the end of theNoE as witnessed by the responsesto the sustainability questionnaire.Currently, the partners explore thepossibility to define common FP7projects to ensure the viability of thestrong bonds that were developedduring the duration of CoreGRID. Mostpromising appears to be the track onSoftware Services. Another promisingdirection on which much of the futurefocus of the Institute will be directedis the Desktop Grids. An FP7 proposalentitled EDGeS: Enabling DesktopGrids for e-Science has been approvedfor a number of partners of the SAInstitute with the aim to integratethe advantages of two important Gridconcepts: service Grids like EGEE andDesktop Grids. In another effort aFET project was proposed aiming tosupport self-evolving, self-describingservice-oriented systems, in order tomake them suitable for the new eraof knowledge aggregation, supportfor user-oriented social networkingand pervasive IT infrastructures.19AnnualReport2007

20CoreGRIDInstitutesAll services must bedesigned to establishfault-tolerant andflexible behaviourin a large-scaleheterogeneousenvironment.Norbert MeyerLeader of the Grid Information, Resource andWorkflow Monitoring Services Institute, PoznanSupercomputing and Networking CenterGRID INFORMATION,RESOURCE AND WORKFLOWMONITORING SERVICES▼The idea of the Grid Information, Resource andWorkflow Monitoring Services architecture is toconvey all the data through the information servicein order to have a standard interface across differentadministrative sites and services. The characterisationof the required information service greatly dependson such factors as the demand placed on the sourceof information (e.g. static versus dynamic, publicationrate), its purpose (e.g. discovery, logging, monitoring)and QoS requirements.One of the main goals of the Instituteon Grid Information, Resource andWorkflow Monitoring Services (IRWM)is to cooperate with other activitiesproviding basic features for the overallGrid architecture. This synergy is to beexpected especially with Knowledgeand Data Management, ResourceManagement, Programming Model,Grid Systems, Tools and Environments.IRWM services are essential to otherInstitutes as they provide data forevaluating the efficiency of systemsand tools resulting from theirresearch. IRWM services also supportthe core functionality necessary forproduction-based Grid environments.The IRWM Institute involves 13CoreGRID partners (FHG, FORTH,INFN, INRIA, PSNC, SZTAKI,UMUE, UNICAL, UIBK, UMEA,UNI DO, UoS, UOW) including 44researchers and PhD students.The work is mostly organised intoresearch groups, units of two ormore CoreGRID partners collaboratingclosely together on common goals.Joint technical reports, publicationsand prototype implementations arethe major measurable outcomes. Oneof the new researches is devoted tomodelling dynamic workflow structuresin higher order chemical languages.The IRWM has a new partner, theUniversity of Innsbruck (Austria),which joined CoreGRID at the endof 2006 and two new associatepartners joining IRWM in 2007:the University of Sannio (Italy)and Umeå University (Sweden).ObjectivesThe primary objective of the IRWMServices research group is to studyand provide general informationand services for the underlying Gridmanagement required by the NextGeneration Grid. The Grid managementservices considered here include Gridcore services and components. Duringthe project the partners of the IRWMdefined several specific objectiveswhich allow us to work out the majorgoals, among others: providingmulti-grain and dynamic monitoring forGrid resources and services, enablingreliable online monitoring of statusand performance for a wide range ofresources, support for extraction andrepresentation of job workflows fromprogramming models, framework foruser management and user and jobseparation, supporting kernel andapplication level checkpointing.The Institute is focused on thefollowing major objectives:

• Providing networkinfrastructure monitoring• Providing monitoring of the progressof complex job workflows• Support for extraction andrepresentation of job workflowsfor programming models• Realising middleware support forcomplex job workflow execution• Framework for user managementand user and job separation• Supporting accounting servicesin virtual environments• Providing checkpoint restartfunctionality in heterogeneousenvironment supportingdynamic job migration• Supporting kernel and applicationlevel checkpointing.AchievementsThe integration work and co-operationbetween three Institutes (IRWM, KDMand RMS) were presented at thejoint CoreGRID workshop in 2007 (inconjunction with ISC 2007) with afirst publication released in 2007.A paper describing the IRWMgeneral architecture was awardedby the Programme Committeeat the WEBIST 2007 conference(International Conference on WebInformation Systems and Technologies,Barcelona, Spain, March 2007).IRWM delivered three major reportsabout the results on the joint researchtopics of all research groups, includingimplementation of prototypes andthe outcome of the integration ofIRWM services with other architecturesdeveloped by CoreGRID Institutes.One of the main challenges whendeploying a Grid workflow managementsystem in a production environmentis the integration of the workflowsolution with existing resources, data,information, and knowledge. The lastreport in 2007 with the title “Reporton workflow integration with resourcemanagement and data and knowledgemanagement” gives an overview ofdifferent aspects that are related tothis challenge and presents a set ofresearch and development activitiesperformed by CoreGRID partners.Three CoreGRID institutes co-organisedin 2007 the 2 nd CoreGRID Workshopon Grid Middleware in conjunctionwith ISC 2007 conference (Dresden,June 2007). 22 papers were acceptedby the Programme Committee fromCoreGRID and the external community.The conference proceedings are underpublication in CoreGRID book seriesin co-operation with Springer.The outcome of IRWM integration workcan be found in several national andinternational projects like CancerGrid,MediGrid, BalticGrid, Progress.discussions during the OGF meetingin Manchester (May 2007) gave usdirect feedback from industry (e.g.Oracle and LMS International) withspecial attention on workflows,checkpointing, and accounting services.In addition several partnersstarted related (national orinternational) projects which usethe CoreGRID integration work.We integrate mainly middlewareservices with emphasise on reliabilityand scalability in production-basedGrid environments. This is of crucialimportance for industry relatedapplications where used infrastructureshould deliver a reliable set of services.It was actually applied in our cooperationwith Telecom companies (e.g.Telecom in Italy - network monitoring;France Telecom - reliability in Grids;Silicon Graphics - reliability of operatingsystems supported by checkpointing).Challengesin 200821AnnualReport2007Relations toindustryThe possibility of accounting theresources used in Grids forms thebasis for introducing the Grid economyconcept.

22CoreGRIDInstitutesThere are majorchallenges in thegeneral adoption ofmanagement andscheduling featuresin productionenvironment.Ramin YahyapourLeader of the Resource Management andScheduling Institute, University of DortmundRESOURCE MANAGEMENTAND SCHEDULING▼Resource management and scheduling are key topicsfor efficient and automatic control in Grids aswell as service-oriented infrastructures in general.The Institute joins renowned experts from all overEurope to foster advanced research in this area toprovide practical and theoretical solutions beyondthe current state of the art. Twenty-four partnerinstitutions with about 100 researchers form thehigh-quality foundation of the Institute.The constituency of the Instituteare experts in different aspectsof the research tasks. Thepartner list includes three newassociated members in 2007:• University of Innsbruck, Austria• CETIC – Centre d’Excellence enTechnologies de l’Information etde la Communication, Belgium• Institute for Parallel Processing,Bulgarian Academy ofScience, Bulgaria• Masarykova Univerzita vBrne, Czech Republic• Centre National de la RechercheScientifique, France• Fraunhofer Gesellschaft zurFörderung der angewandtenForschung e.V., Germany• Forschungszentrum JülichGmbH, Germany• Westfälische WilhelmsUniversität Münster, Germany• Technische UniversitätDortmund, Germany• Konrad-Zuse-Zentrum fürInformationstechnik Berlin, Germany• Magyar Tudomanyos AkademiaSZTAKI, Hungary• Consiglio Nazionale delleRicerche, Italy• Universita della Calabira, Italy• Universita di Pisa, Italy• Technische UniversiteitDelft, The Netherlands• Instytut Chemii BioorganicznejPan w Poznaniu, Poland• Universitat Politecnica deCatalunya, Spain• Ecole Polytechnique Federalede Lausanne, Switzerland• Haute Ecole Specialisee de SuisseOccidentale, Switzerland• The University of Manchester,United Kingdom• The University of Westminster,United Kingdom• CATNETS, European Project• Umeå University, Sweden• University of Sannio, ItalyGrids and Service-orientedInfrastructures (SOI) became commoncore technology for scientific andcommercial environments. Themanagement of large-scale distributedinfrastructures is an increasinglycomplex task, especially consideringthe increasing requirements for newand feature-rich applications suchas workflows and process chains.Suitable solutions for resourcemanagement are essential to supporta flexible and efficient infrastructurethat is easy to use but also supportsmany scenarios. Scheduling is thetask of automatic planning andsteering the resource utilisation fordifferent applications or jobs.

24CoreGRIDInstitutesOur flexibleGrid platform issuitable for a widerange of devices,from portablePDAs to parallelsupercomputers.Vladimir GetovLeader of the Grid Systems,Tools and Environments Institute,University of WestminsterGRID SYSTEMS, TOOLSAND ENVIRONMENTSObjectivesThe research activities of the STEInstitute are organised in four taskswith the following objectives:Generic Platform: This task addressesthe development of a generic,component-based platform, with focuson its architecture, interoperability,security, and design methodology.This platform is specifying the basic“glue” from which higher-levelcomponents and services can beconstructed. Challenges arise fromheterogeneous software libraries,toolkits, operating systems and existingGrid frameworks. The specification ofthis platform underpins the researchareas of the other three tasks.The research activities of the Institute onGrid Systems, Tools and Environments(STE) focus on developing the designmethodology for a generic componentsystem that integrates applicationcomponents, tools/system components,problem-solving environments (PSE),portal components, and infrastructureresources components. The specificationof the Institute’s generic Grid platformsignificantly advances the state ofthe art. It enables the design ofcomponent-based Grid systems with asingle, seamless and “invisible” Gridsoftware infrastructure. Our researchresults are equally valid for both theclient/server and the peer-to-peerparadigms. The Institute’s approachencompasses both the application of thecomponent model and its integrationinto a service-based framework.The STE Institute involves morethan 80 senior researchers and PhDstudents who participate in elevenresearch groups for implementingthe Institute’s roadmap.The STE Institute’s approach enablesthe design of reconfigurable Gridsystems with dynamic propertiesguaranteed by our componentbasedframework. Our flexible Gridplatform is suitable for a wide rangeof devices, from portable PDAs toparallel supercomputers. Beyond thecontributions of the Institute partners,there exist many individual approachesfor building Grid systems, tools andenvironments by other projects.The STE Institute maintains workingcontacts with key projects, proliferatesCoreGRID results, and fosterscollaboration with relevant researchactivities in Europe and worldwide.The STE Institute brings togethertwelve partners – IPP-BAS, USTUTT,ICS-FORTH, IC, INRIA, SZTAKI, UWC,UNIPI, UOW, UPC, VUA, and CYFRONET– from ten different Europeancountries. In addition two newassociated partners – CATNETS andUNIVIE – joined the Institute in 2007.Mediator Components: This task isresponsible for designing a componentsuite that mediates between theapplications and system layers,providing core services according tothe architecture of the generic platform.These include such capabilities asdynamic application steering, metadataretrieval, and service discovery.The components delivering thesecapabilities are integrated and exposedvia a runtime environment that actsas a gateway to system components,thus addressing the integration aspectsof the generic component platform.Integrated Toolkit: This task isspecifying and designing a toolkitfor simplifying the deployment ofGrid-unaware applications while alsooptimising application performance.More specifically, this involvesdefining and mapping applicationrequirements to the component-basedgeneric platform as well as providingapplication interfaces to the mediatorcomponents. The runtime environmentof such an integrated toolkit is ableto run applications in a Grid and

25AnnualReport2007optimise their performance dynamicallyin a way transparent for the user.Advanced Tools and Environments forProblem Solving: This task involvesdesigning PSEs or portals that takelegacy software and automaticallydeploy it as a service that conforms toa standard service model. The aim isto integrate our generic platform intoPSEs and portals allowing users tocompose, steer, monitor and visualisejob execution in a transparent andsimple way. This work is based onidentified deployment scenarios,using technologies for wrappinglegacy code and mechanisms fordeploying and managing services andjobs in peer-to-peer environments.Industryadded-valueBased on the studies performedwithin the STE Institute, the followingjoined projects have recently beenlaunched in order to implement theidentified research and developmentwork. Thus, the STE Institute continuesand expands its research usingthe prototype Grid systems underdevelopment by these projects:• GridCOMP – building anadvanced component platformfor an effective invisible Grid.• XtreemOS – designing a Linuxbasedoperating system tosupport virtual organisationsfor next generation Grids.• EDGeS – creating a Gridinfrastructure that seamlesslyintegrates a variety of desktop Gridswith production service Grids.Those spin-off projects have beenthe main vehicle for applying theimpact of the Institute’s researchactivities in industrial environmentswith direct contribution to improvingthe European economy in the areaof Grid and service technologies. Inaddition, the STE Institute has beeninvolved in the development of fullscaleuse cases in collaboration withindustrial partners via the currentlyactive spin-off projects. Our industrialpartners for this activity include AtosOrigin, Grid Systems, and IBM.Challenges andperspectivesCurrently, the STE Institute isaddressing the following problemsand scientific challenges:• The combination of applicationsand system software to integratedsoftware assemblies is a centralproblem we are addressing. Theaim of this integration is twofold:(1) to allow applications to better andmore flexibly use Grid resources, and(2) to enable system servicesto effectively steer andcontrol their applications.For this purpose, we are designingand building an integratedcomponent system that has asingle glue layer between allforms of components. Thus mostof the complexity of integratingthe many individual softwareitems will be removed.• The development of applicationsto be run on the Grid is stilldifficult, preventing the widespreadadoption from non-expertusers. The challenge in thiscase is to provide developmentand execution environmentsfor Grid-unaware applications,where the Grid resources canbe transparently exploited.• Finally, applications typically haveto be adapted to run on specifichardware platforms. For improvingperformance, the applications haveto be specifically tuned for eachhardware platform. This situationis not feasible in Grid computingenvironments, since the executionplatform can change on a per-jobbasis, and even at run time. Inthese kinds of environments, theapplications have to adapt to thesystems and resources available.By now, the STE Institute has reachedthe roadmap phase of ongoing,integrated research, mostly fosteredby joint projects, such as GridCOMP,XtreemOS, and EDGeS. Havingreached this critical mass of ongoingresearch activity, our future stepsfocus on achieving sustainability aspart of the CoreGRID network by:• Coordinating activities for Institutepartners’ participation in nationaland international research as wellas industrial projects related to Gridsystems, tools, and environments,assuming the results of thisInstitute as starting points to ensurestable and durable cooperation.• Organisation of an annual workshopto discuss and present newdevelopments in the area of Gridsystems, tools, and environments.• Maintenance and update of theexisting Institute web site withthe aim to have a permanentforum durably hosting informationon European research activitiesrelated to Grid systems, tools,and environments, where theannual workshop will alsobe linked in prominently.• Active participation and supportfor the sustainability activities atCoreGRID level including continuouscollaboration with other CoreGRIDInstitutes and constructive contactswith CoreGRID industrial partners.

26IntegrationActivitiesThe aim ofintegrationactivities is toestablish durablemechanisms andinfrastructures forfostering sustainableintegration and restructuringof theNetwork’s research.▼Sergei GorlatchIntegration Leader, University of MünsterThe main objective of the integration activities is toestablish durable mechanisms and infrastructure forfostering the sustainable integration and re-structuringof the Network’s research, and to contribute to theseamless collaboration and dissemination of the workwithin the Network of Excellence. Numerous activitiesare organised and implemented, which will contributeto a high degree of sustainable integration betweenthe partners, with the ultimate goal of overcoming thecurrent fragmentation of Grid research.Co-ordination of thescientific annual roadmapAn annual roadmap has been drawn upfor the six research areas (Institutes)contributing to the CoreGRID JointResearch Programme. The ScientificAnnual Roadmap is intended to beused as a single gateway to thedifferent Institutes’ roadmaps, includinga high-level scientific positioning of thewhole Network within the context of theGrid research landscape. The roadmapis developed in close cooperationwith the Scientific Advisory Board andIndustrial Advisory Board of CoreGRID.The deliverable produced for theScientific Annual Roadmap isavailable on the CoreGRID website:http://www.coregrid.net/Institutes/Co-ordinatedapproach to prepareproject proposalsThis task within the integrationactivities provides support tomembers willing to participate inprojects or programmes partiallyfunded by national, bilateral ormultilateral agencies, leading tobetter integration. The Networkidentified among its members thesuitable contact points to collectinformation on national Gridinitiatives that could generate projectproposals. The same activity wasconducted at the European level bythe project co-ordinator. Fundingsources have been identified anddescribed on a private website. Sofar, several research and developmentprojects initiated by CoreGRIDpartners have been accepted andfunded by the European commission:GridComp, SelfMan, XtreemOS,EchoGrid, Grid test and Bridge.Internal collaborationand disseminationThe CoreGRID internal collaborationand dissemination is managed througha dedicated collaborative tool, namelythe BSCW server regularly maintainedand upgraded by the system manager.This source of information is obviouslyconfidential and thus only availablefor the Network participants inorder to share data and documentsrelated to the Network activities. Inaddition, it provides the partners withthe latest management documentsand project archives. More than240 users are registered and sharedocuments independently of thespecific computer systems they use.

Regular integrationworkshopsOne of the Network’s objectiveshas been to set up a regular, highqualityworkshop for the participantsof CoreGRID from all Institutes. TheCoreGRID Integration Workshop2006 was held in Krakow, Poland,on October 19-20, 2006 at the IFJPAN, attracting 89 participants. Thebest papers were selected by meansof an external reviewing procedureand were published in a Springervolume of the CoreGRID series.The final CoreGRID IntegrationWorkshop 2008 took place inHeraklion, Crete, Greece, on April2-4, 2008, hosted by the Instituteof Computer Science ICS-FORTH,Hellas. The programme featured43 presentations on collaborativework between CoreGRID partners, ofwhich 21 were regular papers and22 were poster presentations. Inaddition, invited talks were givenby Prof. Yannis Ioannidis, Prof. EwaDeelman, and Christos Nikolaou.Sixty-seven participants werealready committed to participatebefore the early registrationdeadline on February, 15 2008.As in previous years, the workshopproceedings will be published at thebeginning of the workshop. The nextstep will be the second review of thebest papers which will be publishedin the final Springer volume.The figure displays the CoreGRIDInstitutes arranged on a circle,showing joint papers submitted to theworkshop in cooperation by severalpartners as lines between them.Grid testbedsThe CoreGRID testbed activities aimat providing researchers with supportto access Grid testbeds maintainedand operated in collaboration withCoreGRID partners. The databasestoring information on experience,policies and best-practice reportsincludes data about testbeds bothon national and European level,which are available for CoreGRIDresearchers. In addition to the DutchDAS and the French Grid 5000, theresearchers can now access the PolishCLUSTERIX, the German VIOLA andthe European PHOSPHORUS testbed,as well as all experiments madeusing these testbeds. A number ofsuccessful experiments have beenconducted using resources of theDAS and Grid’5000 jointly. Experiencereports can be downloaded from thetestbed web pages on the privatecollaborative tool at https://bscw.ercim.org/bscw/bscw.cgi/62053The figure above displays thecurrent topology of the opticalnetwork connections related to theEuropean PHOSPHORUS project.Moreover, a grid testbed based onGlobus Toolkit 4 and UNICORE 6was installed on top of this opticalnetwork. Several CoreGRID partnerscontribute to the PHOSPHOROUSproject and the testbed, whichis thus open for CoreGRIDexperiments. These experimentsespecially contributed towards theQoS of the underlying network.Common understandingof trust and securityThe Trust and Security activityin CoreGRID runs as a horizontalintegration activity related to all theresearch areas studied within theNetwork. It ensures that the Networkparticipants are aware of the useof trust and security technologiesin modern grid environments. EachCoreGRID Institute includes researchgroups focusing on integration workin this area. In 2007, this activityorganised Grid-STP 2007, the FirstInternational Workshop on Security,Trust and Privacy in Grid Systems.Other results are expected through theparticipation in the CoreGRID mobilityprogramme (Fellowship Programmeand Research Exchange Programme)targeted specifically at Grid security.Another important outcome results fromthe joint CoreGRID white paper on thecurrent state of the art of Grid security.In addition, numerous CoreGRIDtechnical reports, presentationsat international conferences andpublication in journals on this topicwere gathered. Central to this activityis the Internet-based CoreGRID Trustand Security Portal, which serves asa communication forum on Grid trustand security and provides informationabout tools, projects, research groups,publications and events. As a way ofillustration, the figure on the left showsa fragment of the security requirementsfor a Grid data management systemusing the KAOS goal-orientedrequirements-engineering methodology(spin-off FP6 project GridTrust).27AnnualReport2007

28CoreGRIDMobility PortalThe new orientationof the MobilityProgramme towardsthe industry is oneof the project assetsfor future researchopportunities.▼In order to increase the level of integration and toimplement collaborative research the CoreGRIDNetwork of Excellence is running and managing aFellowship Programme open to candidates from allover the world and a Research Exchange Programmededicated to visits among CoreGRID members.CoreGRID FellowshipProgramme (FP)The CoreGRID Fellowship Programmeis definitely a great opportunity forpostgraduate researchers to workcollectively on challenging problems asFellows of leading European researchinstitutions. This Programme helpswiden and intensify the network ofpersonal relations and understandingamong scientists. In addition, theProgramme encourages mobility amongresearch groups working in similarareas but in different laboratories.By driving cooperation, Fellowshelp create a strong and durableintegration of Grid research expertisein Europe towards scientific andtechnological excellence.Since the 1st Call of this Programmelaunched on November 15, 2004,a total of 80 applications havebeen received and reviewed by theExecutive Committee. The 4th Calllaunched in March 2006 is still open.Nineteen young researchers wereselected and hosted by one or tworesearch facilities for two distinct6, 9 or 12 month periods. ThisFellowship Programme benefits21 CoreGRID partners plus threeindustrial companies in thefollowing research domains:• Knowledge and Data Management• Programming Model• Architectural Issues: Scalability,Dependability, Adaptability• Resource Managementand Scheduling• Grid Systems, Tools,and EnvironmentsIn the course of the Programme, theFellows closely interact with majorresearchers and leading scientificcommunities. They participate inregular in-house discussions andseminars and contribute to theCoreGRID effort to integrate scientificactivities and dissemination acrossEurope. In addition to the trainingactivities, the Fellowship Programmepromotes career development, ideallywithin the Network to preserveexcellence in the research environment.Throughout and on completionof the Fellowship Programme, theCoreGRID Network provides supportand guidance to the Fellow inhis/her effort to obtain a positionin related research activities.CoreGRID IndustrialMobility ProgrammeBesides the integration inside theNetwork, CoreGRID opened itsMobility Programme to industrialcompanies. The call was launchedduring the First CoreGRID IndustrialConference held in Sophia-Antipolis on December 1, 2006.

29AnnualReport2007Four programmes involving oneto two CoreGRID institutes andone industrial company have beenselected and granted by the Network.In the Industrial FellowshipProgramme, Fellows spend timeat a CoreGRID partner’s institutionand at one of the CoreGRIDIndustrial Advisory Board members’offices. This Programme aims atstimulating knowledge transferand reinforcing CoreGRID’scommitment to taking Grids out ofthe research labs into industry.During the EC review, the externalparticipants involved in theFellowship Programme participatedin the meeting, giving excellentpresentations and providing directfeedback of their experiences.CoreGRIDResearch ExchangeProgramme (REP)The second part of the CoreGRIDmobility activities is the ResearchExchange Programme (REP), whichallows researchers working in oneof the CoreGRID Institutes to visitanother Institute for durations fromfour weeks to six months. ThisProgramme is also open to studentsparticipating in co-PhD supervision inorder to get a joint degree from twouniversities, and to a non-CoreGRIDpartner willing to visit a CoreGRIDmember. Obviously the purpose ofthe visit must be relevant to thejoint programme of activities.Since the start of the project, 22Research Exchange Programmeapplications have been submittedto and approved by the ExecutiveCommittee. To date, 18 CoreGRIDPartners have benefittedfrom this Programme for anaverage stay of 10 weeks.ConclusionThe Industrial Fellowship Programmeis considered as a very positiveinitiative. The CoreGRID Networkof Excellence invests 12% of itsbudget in this activity (€950,000)to increase partners’ integration inthe European Grid landscape. So far28 out of the 41 CoreGRID partnershave taken advantage of this MobilityProgramme. It represents 70% ofthe partners’ Network. This resultdemonstrates that it is an essentialtool for a Network of this size in orderto facilitate partners’ exchange.The new orientation of the MobilityProgramme towards industry isone of the project assets for futureresearch opportunities, as well asfuture potential funding opportunities.Encouraging these exchanges shouldguarantee long-lasting relations andlinks with industry, essential assetsfor ensuring the sustainability of thesix CoreGRID Research Institutes.Results of the MobilityProgramme (2006-2007)InstitutesProgrammeFP REP IFPAM UoS 0 1 0Cie ATOS 0 0 1Cie HITACHI 0 0 2Cie T-Systems 0 0 1CR02 CETIC 2 0 1CR04 CNR 1 0 0CR06 TUD 1 2 0CR07 EPFL 1 0 0CR08 FhG 1 0 1CR09 FzJ 0 0 1CR10 HLRS 0 1 0CR11 FORTH 1 2 0CR14 INRIA 2 6 0CR15 KTH 0 5 0CR18 CCLRC-STFC 2 0 0CR19 SICS 0 3 0CR20 SZTAKI 1 3 0CR21 QUB 0 3 0CR22 UMUE 1 0 0CR23 UNICAL 2 3 1CR27 UCO 1 1 0CR28 UCY 2 1 0CR29 UNIDO 0 1 0CR32 UoM 0 2 0CR34 UNIPASSAU 1 0 0CR35 UNIPI 1 5 0CR36 EIA-FR 2 0 0CR37 UOW 1 0 0CR38 UPC 1 6 1CR39 VUA 1 0 1CR41 ZIB 2 3 0CR42 CYFRONET 0 1 0Grand Total 27 49 10FP: Fellowship ProgrammeIFP: Industrial Fellowship ProgrammeREP: Research Exchange ProgrammeCR: CoreGRID ResearcherAM: Associate Members

34CoreGRIDand Industry▼CoreGRID Institutes are maintaining closerelationships with industry. The objective is tomaximise the impact of CoreGRID integratedresearch activities on European ICT industryby facilitating technology transfer and focusingresearch activities on challenges that match midandlong-term industry requirements.Liaison with industry is an objective that is spreadthrough the whole CoreGRID network, involving everyresearch team. Activities are being organised as partof Spreading Excellence in a series of major initiatives.

The IAB meeting in Pisa35AnnualReport2007The CoreGRID IndustrialLinks Task ForceIn order to boost the links betweenthe CoreGRID Research Institutes,the Network has set up an IndustrialLinks Task Force. Its objectives areto improve technology transfer plansand to define a strategy towardstransferring activities based on anapplication-level view in collaborationwith industry representatives.The CoreGRID Industrial LinksTask Force is composed of:- Thierry Priol, Scientific Co-ordinator,IRISA/INRIA- Philippe Rohou, Administrative andFinancial Co-ordinator, ERCIM- Pierre Guisset, SpreadingExcellence Leader, CETIC- Domenico Talia, Leader of theKnowledge and Data ManagementInstitute, Università della Calabria- Marco Danelutto, Leaderof the Programming ModelInstitute, Università di Pisa- Paraskevi Fragopoulou, Leaderof the Institute on ArchitecturalIssues Foundation for Researchand Technology – Hellas Instituteof Computer Science FORTH-ICS- Norbert Meyer, Leader of theGrid Information, Resource andWorkflow Monitoring ServicesInstitute, Poznan Supercomputingand Networking Centre- Ramin Yahyapour, Leader of theResource Management and SchedulingInstitute, Universität Dortmund- Vladimir Getov, Leader of the GridSystems, Tools and EnvironmentsInstitute, University of WestminsterThe Industrial Links Task Forceinteracts with industry keyrepresentatives in order to:- address and collect theirexpectations, use casesand applications;- identify long-term partnershipopportunities; and- support efficient transfer ofknowledge between CoreGRIDInstitutes and industry inmedium/long-term technologicaland market perspectives.The CoreGRID IndustrialAdvisory Board (IAB)The Industrial Advisory Board is themajor communication link betweenthe CoreGRID Network and industry.The Board was constituted withinthe first six months followingCoreGRID official launch. Itsseventeen members represent largecompanies, SMEs, service providers,hardware or software vendors,and users of grid technologies:- ALGOSYSTEMS SA, Yannis Perros- ATOS ORIGIN, Santi Ristol- DATAMAT, Federico Rossi- EADS CCR, Guillaume Alleon- ERICSSON, Jesus Renero- EUROPEAN MICROSOFT INNOVATIONCENTRE, Fabrizio Gagliardi- FUJITSU SIEMENS COMPUTERS,Bernd Kosch- HITACHI EUROPE SAS, VincentFranceschini & Alessandro Bassi- IBM GRID COMPUTING, John Easton- LMS – NOESIS, Nick Tzannetakis- NOKIA SIEMENS NETWORKS,Daniel Fey- ORACLE, Monica Marinucci& Andrew Sutherland- SAMTECH - OPENENGINEERING, Igor Klapka- SAP RESEARCH CENTRE,Burkhard Neidecker-Lutz- SUN MICROSYSTEMS,Philippe Trautmann- T-SYSTEMS, Michael FehseThe IAB has four primary objectives:- Keep the CoreGRID Networkupdated on the long-term Gridrelatedtechnology needs andchallenges of European industry.- Provide the CoreGRID Networkwith Grid validation cases.- Help identify the market sector(s) tobe addressed within the Grid usercommunity to ensure quick adoptionof Next Generation Grid technologieswithin European industry.- Report recommendations to theCoreGRID Scientific Advisory Boardwith respect to future strategicGrid-related research objectives.Its mission is to ensure that CoreGRIDresearch significantly supports theEuropean ICT industry and contributesto accelerating Europe’s drive toturn its substantial Grid researchinvestment into tangible economicbenefits. IAB meetings are chaired byPierre Guisset (Spreading ExcellenceLeader). Monica Marinucci (ORACLE)has taken the role of Board Secretary.Taking the opportunity of having mostof the IAB members attending theOGF20 event, the third IAB meetingwas organised at the Universityof Manchester on May 10, 2007,following the request expressedduring the CoreGRID Industrialconference to organise the thirdIAB meeting during a Grid event.

36CoreGRIDand IndustryLiaison with industryis an objective thatis spread throughthe whole CoreGRIDnetwork, involvingevery research team.The meeting focused on collaborationopportunities between IAB membersand CoreGRID Institutes. Startingfrom CoreGRID fellows’ technicalpresentations, interactive roundtablesessions were organised perInstitute, leading to the definition ofcollaborative research projects andto Industrial Fellowship proposals.The Industrial FellowshipProgramme (IFP)The CoreGRID Fellowship Programmehas been extended to involve industrialcompanies. According to the updatedrules, fellows are invited to spend from12 to 18 months in one or two of theCoreGRID institutions, out of whichtwo to six months must be within thepremises of an industrial partner.The training programme of the fellowis defined in close cooperationbetween the CoreGRID member andthe industrial company. The industrialcompany is co-funding the programme.In 2007, four programmes havestarted on the following subjects:- Comparative Study over EfficientData Transport Protocols in Grids- Data Management for High-Performance DistributedMultimedia Content Analysis- SLA & Contract Negotiationfor the Grid- SLA for supporting use of licensedsoftware in Grid environmentsThe Open GridForum (OGF)CoreGRID is a silver organisationalmember of the Open Grid Forum (OGF).The Network sponsored OGF Fellowsand numerous Network membersparticipated in the OGF 20 in Manchesterin May 2007. The key objective of OGFbeing to share technological advancesbetween enterprises and scientists,thereby promoting the broad adoptionof Grid technology, it is important forCoreGRID to take part in such an eventand to demonstrate the quality of itsresearch activities involving industrials.Within the frame of OGF20, CoreGRIDorganised a Workshop entitled“Evolutions of GRIDs Towards ServiceOriented Knowledge Utilities (SOKUs)”,moderated by IAB members andCoreGRID partners. This Workshopwas intended to initiate a technicaldiscussion about the SOKU visionallowing exchange of individualviews on this transition fromkey stakeholders represented byleaders in industry and science.The workshop was very well attendedwith more than 50 participants(actually limited by the capacity ofthe room). This showed the interestin the particular topic of SOKUs aspart of the European Grid strategy.The workshop facilitated several vividdiscussions and interaction with theaudience. It became clear that theSOKU vision includes several aspectsand perspectives and not a singularvision. The presentations showed manydifferent facets from standardisationactivities, several existing projects,and the expectations from commercialstakeholders as well as the vision of theEuropean Commission as implementedin the current work programmes. Overall,there is a clear trend of convergencebetween Grids, service economies,different application scenarios either incommercial or scientific environments.

37AnnualReport2007Networked EuropeanSoftware & ServicesInitiative (NESSI)In September 2005, NESSI was set upby thirteen European ICT industriesas an ICT European TechnologyPlatform. NESSI is a major Europeanindustry initiative which aims atdriving innovation throughout thesoftware and IT services sector.The NESSI mission is to develop avisionary strategy for software andservices driven by a common Europeanresearch agenda, where innovation andbusiness strength are reinforced by:- providing European industryand the public sector withefficient services and softwareinfrastructures to improve flexibility,interoperability and quality- mastering complex softwaresystems and their provisionas service-oriented utilities- establishing the technological basis,the strategies and deploymentpolicies to speed up the dynamicsof the services eco-systemCoreGRID Institutes are collaboratingwith NESSI and several NESSI workinggroups, specifically about ServiceOriented Infrastructure, SoftwareEngineering and Trust, Securityand Dependability. This resulted incontributions to the NESSI StrategicResearch Agenda and in severalCoreGRID members partnering withNESSI enterprises in setting up winningFP7 NESSI Strategic Projects (S-Cube,SOA4ALL, SLA@SOI, RESERVOIR, etc.).Member survey onIndustrial linksIn order to assess the level ofcollaboration between CoreGRIDpartners and industry, a questionnairewas sent to the NoE partners in earlyAugust 2007. The objective was togather homogeneous input in order tobuild a panoramic view of CoreGRIDrelationships with industry. Answerswere also expected to reveal towhich extent the Network had beeninstrumental in encouraging andfacilitating these industrial links.The survey revealed that over93% of the CoreGRID membershave active links with industrialpartners and that 86% are claimingthat CoreGRID was instrumentalin initiating or improving theirrelationship with the business world.Beyond the many interestingperspectives that this survey providesto CoreGRID, the most interesting andrewarding finding is the fact that alarge majority of the members couldlean upon the CoreGRID Network ofExcellence to initiate or develop fruitfulrelationships with industrial partners.In that sense, the survey brings a clearconfirmation that CoreGRID playedits role in connecting its memberswith industry at local, national,European and international level.PerspectivesDuring its third year of activity, CoreGRIDhas not only succeeded in integratingand coordinating the European Researchcommunity in Grid technologies, but alsoin connecting the academic researchinstitutes to industry in order to fullyrealise the objective of boosting the EUICT Industrial sector through bringingresearch and innovation to business.

38CollaborationGatewayCoreGRID isleading the taskscollaboration onroadmaps andtraining activities.Wolfgang ZieglerCollaboration Gateway Leader,Fraunhofer Institute, SCAI▼The CoreGRID Collaboration Gateway bundlesmajor activities aiming at collaboration with otherGrid-related projects of the seventh frameworkprogramme. The activities in the Collaboration Gatewayare organised in seven sub-tasks, which areled by different CoreGRID partners:1 Exploitation of synergies andtechnical co-ordination (leader INRIA)2 Joint fora for exchange anddissemination (leader CETIC)3 Co-ordination of standardisationefforts (leader FHG)4 Repository of referenceimplementations and Gridmiddleware (leader FHG)5 Collaboration on roadmaps(leader FHG)6 Training activities (leader UPC)7 Collaboration with NESSIplatform (leader CETIC)When taking a closer look at theEuropean Grid projects of the sixthframework programme it becameobvious at an early stage that despiteall differences of the projects’ focusareas, each one tends to implement asmall set of similar tasks, e.g. relatedto dissemination, standardisation,software repositories, or training. Inparticular, the larger type of projects(Integrated Project (IP) and Networkof Excellence (NoE)) put substantialeffort into these activities. Thus, theidea of making resources and resultsavailable to other projects is quitenatural and was already implementedearly in the sixth frameworkprogramme through the co-ordinationactivities. The leadership of thesetasks on a European level has beendistributed among the IPs and theNoEs. CoreGRID is leading the taskscollaboration on roadmaps and trainingactivities. Yearly events are organisedby the projects for exchanging theresults of the ongoing collaborationactivities and the planning ofthe following year activities.1. Technical synergiesBased on the foci of research anddevelopment of the different EuropeanGrid-related projects, a number ofareas have been identified for crossprojecttechnical co-ordination and thefollowing eight technical groups (TG)have been set up and are working:TG1 Grid Architecture, TG2 Ontologies,TG3 Workflows, TG4 Monitoringand Fabric Management, TG5 DataManagement, TG6 Trust & Security,TG7 Grid Economics and BusinessModels, TG8 Virtual Organisations.The TGs published yearly white paperson related research and developmentto identify gaps that should beaddressed in future projects andpossible synergies arising from thecollaboration. In addition to the annualco-ordination events, the TGs organisean additional annual meeting for thepresentation and discussion of thegroups’ results and the structuring ofthe work for the following period.2. Joint fora forexchange anddisseminationIPs and NoEs are strong atdisseminating their results and havethe necessary resources to do so. Thistask aims at identifying and using jointfora for exchange and disseminationof project results. There are several

clear benefits in co-ordinating thedissemination activities. Largeraudiences are reached by using thedifferent channels established by theprojects. Joint events usually attractmore participants. Small projectswith limited resources may hook upand use the channels and eventsmaintained by the bigger projects.Finally, these may be achieved withoutsignificantly increasing the effort in theindividual projects. One example is theCoreGRID newsletter, which is open tocontributions from other projects aswell. CoreGRID also submits articles onresearch activities and results in otherprojects newsletter, etc. Additionally,CoreGRID started in 2007 organisingthe CoreGRID Symposium, whichaims to become the largest Europeanconference focussing on Grid research.3. Co-ordination ofstandardisation effortsMany European projects are relying onexisting or evolving Grid standards.A number of them are actually alsocontributing to the development ofstandards in different standardisationbodies while other projects haveidentified requirements for standardsthat are not yet addressed. The numberof European co-chairs and participantsof the research and working groupsof the Open Grid Forum has increasedsignificantly over the last several yearsas a direct result of this activity. Tostrengthen the European impact in thestandardisation process, the projectscollaborate in the Grid StandardsCo-ordination Group (GSCG) whereeach project is represented. The GSCGholds regular face-to-face meetingsand teleconferences and has produceda white paper. The white paperdescribes the standards activities ofthe projects, standards requirements,and bodies where project membersare already active. It also identifiesthe bodies to which further standardsactivities should be directed.4. Repositoryof referenceimplementations andgrid middlewareWithin this task, CoreGRID is focussingon creating and maintaining the“CoreGRID Repository of referenceimplementations and Grid middleware”to be filled with Grid-relateddevelopments by CoreGRID partnersover time. A Quality AssuranceGroup (QAG) has been set up, whichhas defined the process to followto ensure uploads of high-qualityGrid software components. EachCoreGRID Institute has appointed arepresentative for the QAG acting asa contact point for institute memberswilling to contribute Grid software. Thefolder hierarchy follows the researchareas of the CoreGRID institutesand the technical groups. Moreover,the repository will provide links torepositories maintained by otherprojects or initiatives. The BEinGRIDproject has agreed to maintain asoftware repository on a Europeanlevel. The CoreGRID repository willbe cross-linked with the BEinGRIDone to allow easy access to Europeansoftware developments withoutduplicating the management effort.5. Collaborationon roadmapsBased on the annual roadmaps createdby the CoreGRID Institutes and withadditional contributions from the otherGrid-related projects, this collaborationactivity has produced a first versionof a European Grid Roadmap, whichwas prepared by representativesfrom all projects in the European GridRoadmap Group (EGRG). The EGRG isresponsible for gathering informationfrom all projects relevant to theEuropean Grid Roadmap, includingproject focus, planned developments,timelines, etc. The structure of theroadmap document follows thethematic grouping of the CoreGRIDinstitutes complemented by the topicsof the Technical Groups that have nocorresponding CoreGRID institutes.The European Grid Roadmap iscurrently being updated incorporatingcontributions from several sources:(i) the current version of the annualroadmaps of the CoreGRID Institutes,(ii) achievements made in the otherprojects, (iii) results from the TechnicalGroups, and (iv) contributions fromnew projects that have been launchedsince the last publication of theroadmap document. The updatedversion includes an overview ofthe research and developmentsplanned or made in the differentprojects and a SWOT analysis. Thedocument is available in the CoreGRIDrepository (http://www.coregrid.net/mambo/content/view/58/79/).6. Training activitiesThe goal of this collaboration taskis to co-ordinate training activitiesorganised by different projects and todefine a training activities roadmap atthe European level. This allows betteruse of the resources and ensures thatsmaller projects (STREPs) benefit fromthe training organised by the largerones. The group cross-disseminatesthe training activities through mail andvia the collaboration website. It is alsoparticipating in the training activitiesof the Open Grid Forum. In addition,the group jointly organises sometraining events, e.g. the CoreGRIDsummer school with Summer School2007 in Budapest, where severalprojects contributed to the programme.The training material is also madeavailable through the CoreGRIDrepository and the ICEAGE repository.7. Collaborationwith NESSIThe objectives of this task are toallow all Grid projects to be awareof the evolution of the NESSI Visionand versions of the Strategic ResearchAgenda. Also, it should promote theparticipation in specific working groupson research topics of the platform.Significant impact on the alignmentof the projects’ R&D is expected, asNESSI is the Networked EuropeanSoftware and Services InitiativeEuropean Technology Platform aimingto provide a unified vision andstrategic research agenda for Europeanresearch in Software and Services byestablishing the technological basisand developing strategies that willspeed up Europe’s transition to aknowledge-based economy throughservice-oriented business models.After a couple of years of experiencewith the European concertationactivities, it may be concluded thatCoreGRID achieved a substantialimpact as briefly detailed inthe previous paragraphs.CoreGRID is one of the largestEuropean Network of Excellencewith 46 partners from 19 countries,a NESSI partner, a sponsor of theOpen Grid Forum. CoreGRID has aleading position in the EuropeanGrid research and Grid expertise.39AnnualReport2007

40FinancesThe opportunityoffered to theNetwork ofExcellence tofund part of themanpower has hada strong impact onthe researchers’integration.Philippe RohouAdministrative and Financial Co-ordinator, ERCIMDetailedbreakdownamong activities▼Financialresources -overview andbreakdownThe first three years of the Networkproved that CoreGRID satisfiedmost of the researchers’ needs. Theopportunity offered to the Networkof Excellence (funded under theSixth Framework Programme) tofund part of the manpower has hada strong impact on the researchers’integration. The budget flexibilitygiven by the European Commissionhas allowed important changes infinancial allocations to the six majoractivities. Network membership hasfinally been able to evolve accordingto partners’ needs and participation.BudgetThe CoreGRID Network of Excellenceis the only network funded by theEuropean Commission’s Service andSoftware Architectures, Infrastructureand Engineering Unit. The CoreGRIDbudget allocated by the EuropeanCommission amounts to a maximumof €8.2 million. This grant will bedistributed over a period of four yearsamong the 41 partners, depending ontheir activity and commitment levels.Until now, the Members’General Assembly has agreedto use the European budget tofund six major activities:• Administrative co-ordination• Scientific co-ordination• Integration activities• Spreading Excellence• JPA (Joint Programme ofActivities) Grant to Scientists• Various activitiesIt has to be emphasised that theproject is only partially funded bythe European Commission. The totalestimated costs for the full durationof the project were evaluated atmore than €19 million, while the ECfunding will not exceed €8.2 million.The budget for CoreGRID activitieswas agreed upon by the consortiumbefore the start of the project, andfinancial plans for 12, 18 and 48months have been established. Thebudget distribution is not frozenand was adjusted to match theNetwork’s evolution and needs. Inparticular the four-year plan hasbeen established as follows:Administrative and scientific coordinationcosts correspond to 18%of the overall budget. These include:• part of the salaries and travelcosts for the administrativeand scientific teams;• a lump sum allocated tothe Workpackage leaders,IMC and MGA Chairmen;• a system manager and provisionof collaborative tools; andaudit certificates costs.Integration and Spreading of Excellenceactivities are allocated an estimatedbudget of €1.86 million (representing22% of the overall budget) andinclude the following activities:• a research exchange programmeto encourage internal shorttermmobility (2%);• a fellowship programme toattract bright young scientists foreighteen-month periods (9%);• publishing and disseminationactivities (annual summerschools, annual report) (8%);• annual integration workshops;and sustainability (WP1 transversalactivity) + SOA-related tasks.

This allocation isbased on the number of researchersinvolved in each institute and eachactivity. The involvement of thepartners evolves in accordance withthe Network’s needs as discussed atthe annual meetings of the Scientificand Industrial Advisory Boards.The total expenditure for the entirenetwork duration (48 months) hasbeen refined according to the realcosts submitted during the firstthree years of activity and to theplanned budget for the last year.CoreGRIDGlobal BudgetThis distribution has been mappedto the Network’s actual activities.The budget is divided into six fixedsections (see “detailed breakdownamong activities”) so that acomparative analysis can be performedwith the previous years’ figures. Themain part of the budget is dedicated toresearch and dissemination activities.Third yearactivitiesAll Network activities are fullyoperational since the beginning of yeartwo. In year three, the expenditurelinked to Network coordination andto various activities remained stable.Meanwhile the Spreading of Excellencebudget has been regularly increasedto support the Network’s efforts indisseminating its results (summerschools, integration workshops andindustrial conferences). The mostsuccessful activity during this 3rd yearhas been the mobility program; 70%of the Network partners benefitedfrom this programme. Nineteen fellowswere recruited all over the world and22 visits were organised betweenPartners and/or Associate Partners.These budgets made possiblethe organisation of high qualityconferences and events which are key16001400120010008006004002000factors for the successful integrationof our 41 partners. In addition, themobility programme was adapted tosupport joint collaboration betweenCoreGRID partners and Industry; atool which proved very efficient inimproving the transfer of resultsfrom our research institutes towardsindustry. Closely interacting withindustry is a key asset of the project,from which future research andpotential funding opportunities mayresult. The consortium will investigateall future opportunities while preparingits final sustainability plan.Despite the complexity of the Networkof Excellence regulations, the budgetallocated by the Commission in 2004will be fully used by the end of theproject and all activities foreseenand added during the project lifetimewill be completed. This is the resultof a strong partnership and ofefficient project management.12 months actual cost1 st Sept. 04 - 31 Aug 0524 months actual cost1 st Sept. 05 - 31 Aug 0636 months actual cost1 st Sept. 06 - 31 Aug 07Third year activities

42Major Resultsand SustainabilityAfter three years ofexistence, CoreGRIDhas carved out aplace for itself in theinternational Gridresearch arena.▼After three years of existence, CoreGRID has carvedout a place for itself in the international Gridresearch arena. It has become one of the largestresearch centres in Grid computing, encompassinga vast range of research topics such as knowledgeand 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 thirdyear is the right time to list all the achievementsaccomplished by the network and not only the activitiesperformed in 2007.• Organisation of 59 meetings and 17workshops, contributing to solvingresearch challenges as described inthe CoreGRID research roadmaps.• Delivery of more than 447 jointtechnical papers accepted in peerreviewedconferences, workshopsand journals, including six highlyreputed CoreGRID series volumes,thus advancing European excellence.• Publication of 122 CoreGRIDtechnical reports, co-authored by atleast two different CoreGRID partnersshowing the level of integrationamong the CoreGRID community.• The effective kick-off of severalspin-off research projects, fundedeither by the European Commissionwithin the 6th and the 7thFramework Programmes, or throughnational and/or regional initiatives• GridComp: STREP - FP6-ISTCall 5 (Starting date: 1 June2006 – Joint partners: INRIA,ERCIM, UoW, CNR, UCHILE)• XtreemOS: IP - FP6-IST Call5 (Starting date: 1 June 2006– Joint partners INRIA, CNR,ZIB, VUA, STFC, UPC)• Selfman: SSA - FP6-IST Call5 (Starting date: 1 June 2006– Joint partners INRIA, UCL)• GridTrust: SSA- FP6-IST Call 6(Starting date: 1 June 2006 – Jointpartners CETIC, STFC, CNR, VUA)

CoreGRID alsosponsored the Open Grid Forum.• Opening up academic researchagendas in order to identifybusiness-oriented researchpriorities, leading to the spinoffof new CoreGRID activities,for example in service-orientedarchitectures and systems.• Developing new ideas to anticipatetechnological trends and topromote commercially relevantand promising research.• Active involvement of industrialstakeholders to help identify takeupopportunities beyond publiclyfunded programmes, thus stimulatingthe investment of industrialstakeholders in CoreGRID institutes.• Setting up a Grid User Communityin order to raise public awareness.• Organisation of several scientificworkshops jointly with highlyreputed international conferencesand the CoreGRID symposiumjointly held with EuroPar 2007.• Organisation of three annualCoreGRID Summer Schools.• Implementing Mobility Programmes- a Fellowship Programme and aResearcher Exchange Programme- increasing integration betweenpartners, and now involvingindustrial members of the IAB.• Organisation of three annualIntegration Workshops.During the fourth year, the Networkis committed to implementing itssustainability plan. This is more than acommitment; it is also an enthusiasticdetermination from all participantsto continue to work together andaddress new research challenges.The idea to set up CoreGRID came in2002 and since that date, computingtechnologies have evolved and Gridis merging with some prominentconcepts such as Service and Cloudcomputing. But the initial idea remainsthe same and our vision is still valid:how to set up a fully distributed,dynamically reconfigurable, scalableand autonomous infrastructureto provide location independent,pervasive, reliable, secure andefficient access to a coordinated set ofservices encapsulating and virtualisingresources (computing power, storage,instruments, data, etc.) in order togenerate knowledge. Grid computinghas paved the way towards newcomputing systems that consider theInternet as a computing infrastructureper se. The Grid research communitycan be proud of what it did over thelast ten years: it has shown that alarge scale distributed computinginfrastructure can be implemented anddeployed over the Internet to supportthe execution of e-Science applicationsand to serve a wide spectrum of users,thereby answering their needs foradvances in their own research field.CoreGRID will play an importantrole in the transition from Grid toService computing. It already featuresa set of activities targeting serviceinfrastructures, in particular in thearea of Trust & Security, Service LevelAgreement and Middleware Systems.CoreGRID has also acquired valuableexpertise in coordinating a researchcommunity. CoreGRID will evolve froma Network of Excellence towards anERCIM working group covering bothGrid and Service computing. It willact in a complementary way withother projects such as the S-CubeNetwork of Excellence in which severalCoreGRID partners are involved.This Working Group is being set upand will be operational by 2008 inorder to ensure a smooth transitionbetween the EC-funded NoE and theself-sustained WG, while maintainingthe momentum of the Europeancollaboration on GRID research.
