Held telcons after that to discuss schemas, metadata, etc. Documents: Special Edition of C&C:P&E nearly ready (Fox) Planning another for next year -- what topic? Grids 2002 book in process, chapters on GCE’s (Fox) Need to revise charter

4 GCE Workshop, June 6-7, 2002 Held in Bloomington, IN > 25 attendees 7 sessions Web services project presentations Technology update presentations Testbed schema design discussions

5 GCE June ‘02 Workshop Summary (cont.) Project Presentations: A Web Services Data Grid (Chip Watson, Jefferson Labs). K12 Portal and Batch Job Web Services Portal. (Josh Hone, Jefferson Lab/Florida State University). IPG Computing Environment (Warren Smith, NASA Ames ) Arun Jagatheesan: Data Grid Management System Marlon Pierce: Application Services

8 GCE June ‘02 Workshop Summary (cont.) Conclusions: Web services are being used by a few projects. Still want to test interoperability issues Plans for GGF5: Best to hole a combined session on Jobs, Workflow, Metadata aznd relationship to GCE, no BOF’s or WG’s. Agree to do something for SC02? GCE Scotch BOF Develop next direction based on OGSA, etc. Revise Charter GCE Web Services Testbed Develop web services and the schemas needed for testbed

9 GCE Sessions 1&2: Grid Jobs - Metadata and Management Grid Computing Environments Must specify & manage “jobs” Execute on the grid These are execution management engines Workflow specification languages such as WSFL and Xlang Goal of today’s presentations: form first step towards a GCE survey document covering the different approaches used by the various groups. Survey document: form the basis for future work on classification/abstraction of metadata and management of grid jobs Consider possible GCE testbed activity?

10 GCE GGF5: Session 3 survey Charter discussions What is next direction and/or major activity? GGF6 Plans
