Potential topics to discuss:
============================

• DM & WMS integration (DAGs, replication, etc.)
• L&B advances (more information from WMS, DM)
• collaboration with JRA4 (should we invite them as well?)
• VM technologies (globus)
• configuration, instrumentation, logging
• security models for data mgmt
• security vulnerability
• Harmonization of logging and error handling

15:00 → 18:00 WMS & DM & LB I

This session should include:

• Combining compute and data jobs in DAGs
• WMS using data mgmt for
• providing input data at execution site
• storing results (sandboxes?)
• Use of L&B for logging computational and data jobs
• Adding job statistics (CPU time etc.) to L&B

15:00 Sparse sandboxes and scenarios for sandbox management via DM services.

The current support for the handling of 'sparse' sandboxes via the WMS web service interface (a.k.a. the WMproxy) is described, and possibly demonstrated. Missing features and scenarios for extending this model to storage elements that do not provide a gridftp interface will be discussed.

16:00 Coffee

16:30 Scenarios for integration of Data with Job Scheduling

There are many possibilities how to integrate 'data' and 'cpu' jobs. The CONDOR Stork component is one very good candidate to integrate to achive easy interoperability which would need to be explored.

Speaker: Peter Kunszt (CERN)

17:15 DAGs with Data Placement nodes: the "shish-kebab" jobs.

We try to sort out a few details of which information needs to be passed among the various nodes of a DAG with data placement nodes, with a special care on when and how matchmaking should be performed.
