A Nation Wide Experimental Grid

1. A Nation Wide Experimental Grid • The Grid’5000 project: architecture and objectives • Building a nation wide experimental platform for Grid researchers • 10/11geographically distributed sites • Every site hosts a cluster of PCs (from 256 CPUs to 1K CPUs) • All sites are connected by RENATER (French academic network) • RENATER hosts probes to trace network condition load • Design and develop a system/middleware environment for safely test and • repeat experiments • Use the platform for Grid experiments • Address critical issues of Grid system/middleware • Programming, scalability, fault tolerance, scheduling • Address critical issues of Grid networking • High performance transport protocols, QoS • Gridify and test real life applications • Investigate original mechanisms • P2P resources discovery, desktop Grids • The Grid’5000 Steering Committee • Organizer: Franck Cappello (LRI, CNRS-Universite Paris-Sud) • Director of the ACI GRID : Thierry Priol (IRISA, Rennes) • President of the ACI GRID SC : Brigitte Plateau (IMAG, Grenoble) • Director of RENATER : Dany Vandrome • Sites scientific coordinators • Frédéric Desprez (INRIA Rhône-Alpes) • Michel Daydé (ENSEEIHT-IRIT Toulouse) • Yvon Jégou (IRISA, Rennes) • Stéphane Lanteri (INRIA, Sophia Antipolis) • Raymond Namyst (LaBRI, CNRS-Université de Bordeaux 1) • Pascale Primet (INRIA Rhône-Alpes) • Olivier Richard (IMAG, Grenoble)
