2 Grid’5000 GdX Grid'5000 and Grid eXplorer 2 Grid raises a lot of research issues: Security, Performance, Fault tolerance, Scalability, Load Balancing, Coordination, Message passing, Data storage, Programming, Communication protocols and architecture, Deployment, etc. Theoretical models and simulators cannot capture real life conditions Production platforms have strong difficulties to reproduce experimental conditions How to test and compare? Fault tolerance protocols Security mechanisms Deployment tools etc. Grid experimental platforms rational

Platforms) 2) Strong interaction between these research tools Tools for Large Scale Distributed Systems Real systems Real applications “In-lab” platforms Synthetic conditions Key system mecas. Algo, app. kernels Virtual platforms Synthetic conditions
