1. TeraGrid Capability Discovery John-Paul “JP” Navarro TeraGrid Area Co-Director for Software Integration University of Chicago/Argonne National Laboratory May 8, 2007

2. JP Navarro 2 Capability Discovery BIS (Before Information Services) Coordinated TeraGrid Software and Services “CTSS” (Versions 1-3) –Monolithic capability stack Compilers, MPI, math/data libraries, many tools, & grid software Grid services –19 diverse resources (Cray, BG/L, and clusters) –User discovered thru static documentation

3. JP Navarro 3 CTSS 4 Architecture Modular capability architecture –Support diverse Grid resources (compute, data, instruments, etc) –Support arbitrary capabilities –Open source capability development and implementation –Flexibility to deploy on subset of resources –Increased speed and flexibility to update capability Capability information services –Used for user documentation –Used for user portal –Used by science gateways –Used by user applications

4. JP Navarro 4 CTSS 4 Capability Kits Operational Capability (required) –TeraGrid Core Integration User Capabilities (optional) –Remote Login –Remote Computation (GlueCE related) –Data Movement (GlueSE related) –Data Management (collections) –Wide Area Parallel File System –Application Development & Runtime –Science Workflow Support –Parallel Application Support –Distribute Parallel Application Support

5. JP Navarro 5 CTSS 4 Capability Discovery Story 1 –Which grid resources offer a specific capability? Story 2 –Which capabilities are available on a specific resource? Story 3 Given a specific capability and resource: –Where are the service endpoints and what are they –Which user selectable software component are provided and how do I access them

6. JP Navarro 6 CTSS 4 Technical Design – –Kit Attributes: »Name, Version »Current, Target Support Levels – »Name, Type, Version »Endpoints – »Name, Version »Access handles
