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

What our users want...
Two primary applications: Cactus and Trianaother application communities are also being engaged,
Application oriented environment Resources (grid) on demandAdaptive applications – adaptive grid environment
job checkpoint, migration, spawn off a new job when needed,
Open, pervasive, not even restricted to a single Virtual OrganizationThe ability to work in a disconnected environment
start my job on a disconnected laptop; migrate it to grid when it becomes availablefrom laptops to fully deployed Virtual Organisations
Mobile workingSecurity

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?

GAT: What is It?
GAT: Grid Application ToolkitImplements the GAT-API
Used by applications (different languages)
GAT Adaptors Connect to capabilities/services
GAT EngineProvides the function bindings for the GAT-API
Grids Info Day, 25 March 2003, Brussels
GAT
More or less …Set of calls GAT_ToolOrService(arguments)
Your chosen tools/services: resource brokers, information servers, application managers, grid monitoring, data managers, notification, etc.
Set of APIs for dealing with the GAT (registration, information, errors, fault tolerance)
