Something different ?

1. Something different ? Pierre Kuonen EIA-FR SOS8 Charleston 2004

2. Why CoreGRID ? • Most current Grid projects are goal driven • There is strong pressure to develop a working environment from the Grid promoters, end-users and institutions that provide funding • There is a lot of engineering activities but little research in computer science • Lack of visibility of European contributions to the development of the Grid Foundations • Lack of critical mass (research activities are widely dispersed and uncoordinated) • What are the consequences ? • Lack of long term research to shape the Next Generation Grids • A research community that is not yet well identified and sustainable • Serious possibility of repeating history (GRID next buzzword after HPCN, AI) SOS8 Charleston 2004

3. CoreGRID objectives • To build a European-wide research laboratory • Create the European “Grid Lighthouse” and be seen as such worldwide • To achieve integration and sustainability • To build solid foundations for GRID and Peer-to-Peer (P2P) technologies • Both on a methodological basis and a technological basis. • Support medium and long term research activities • Achieve and promote scientific and technological excellence • Gather and disseminate European research • A think-tank for spin-off projects • EC funded, bilateral projects, … SOS8 Charleston 2004

4. CoreGRID membership • 42 partners • 18 Countries (1 from S. America) • 118 Researchers • 199 PhD Students VTT IC RAL-CCLRC U. Belfast U. Cambridge U. Cardiff U. Manchester U. Newcastle U.

5. Main issues • Exploiting huge but elusive resources • resource discovery, reservation/allocation, scheduling, fault tolerance, load balancing • Handling massive, uncertain and unreliable state information • distributed and decentralised management and DB, trust and security • Going beyond the conventional programming model • multiple and flexible parallelism, at run time adaptation SOS8 Charleston 2004

6. Uniform Request Datawarehouse Resource Discovery Scheduling ResourceAllocation/Reservation Monitoring Our approach SOS8 Charleston 2004

7. What scientists need • From “program centric” vision to“service centric” vision • Program-centric • Execute my program on my specified resources • Service-centric • Provide me some services with a given QoS, no matter where they are located and executed SOS8 Charleston 2004

8. A set of well identified research challenges • Knowledge & Data Management • Handling information/data that are required/produced by a wide range of diverse processing power • Programming Model • Making the programming of Grid infrastructures as simple and transparent as possible • Resource Management • Handling efficiently a large range and quantity of heterogeneous resources • Scheduling • Scheduling jobs/applications/tasks/computation within a Grid environment • System Architecture • Designing the next generation Grid middleware • Problem Solving Environments, tools and GRID systems • Integrating various middleware, tools and applications for problem solving SOS8 Charleston 2004

9. How to share resources • We do not built HPC machines • We use existing ones • Who agree to give us cycles • To whom do we agree to give cycles • How can we take advantage of your cycles • Resource discovery and management • Which applications can take advantage of your cycles • Mapping applications to machines SOS8 Charleston 2004

10. What CoreGRID can possibly do for you?? • Is this approach of any interest for you ?? • Resource management is a major issue in huge systems • Mapping applications to machines is an important issue • How to represent an application together with its requested QoS • To go beyond MPI programming paradigm • Standard..
