GridLab A Grid Application Toolkit and Testbed IST Jarek Nabrzyski GridLab Project Coordinator Poznań Supercomputing and Networking Center

Grids Info Day, 25 March 2003, Brussels GridLab EU funded project, involving 11 European and 3 American partners, January 2002 – December 2004 Main goal: to develop the Grid Application Toolkit (GAT) and set of grid services and tools... resource management (GRMS), data management, monitoring, adaptive components, mobile user support, security services, portals,... and test them on a real testbed with real applications

Grids Info Day, 25 March 2003, Brussels What our users want... Two primary applications: Cactus and Triana other application communities are also being engaged, Application oriented environment Resources (grid) on demand Adaptive applications – adaptive grid environment job checkpoint, migration, spawn off a new job when needed, Open, pervasive, not even restricted to a single Virtual Organization The ability to work in a disconnected environment start my job on a disconnected laptop; migrate it to grid when it becomes available from laptops to fully deployed Virtual Organisations Mobile working Security

Grids Info Day, 25 March 2003, Brussels What our users want... (cont.) The infrastructure must provide capabilities to customise choice of service implementation (e.g. using efficiency, reliability, first succeeding, all) Advance reservation of resources, To be able to express their preferences regarding their jobs on one hand and to understand the resource policies on the other hand, Policy information and negotiation mechanisms what is a policy of usage of the remote resources? Prediction-based information How long will my job run on a particular resource? What resources do I need to complete the job before deadline?
