  1. WP4 / ATF ATF meeting, Paris project conference, 6/3/2002 German.Cancio@cern.ch

  2. Outline Analysis of WP4 • Dependencies on external Software • Dependencies on SW provided by other WP’s • Vagueness of responsibilities/ holes in functionality between WP’s • Redundancy/duplication of WP’s

  3. Analysis of WP’s: WP4 (I) (Runtime) Dependencies on external Software • LCFG • Globus: • gatekeeper/GRAM • No feedback from Authorization group on LCAS component • MDS-2 info provider specification • (what will be the impact of Globus3 and the OGSA?) • Operating system • RH Linux -> when to migrate to 7.2? Support for 6.2? • What about other platforms (Solaris)? • Batch systems • LSF, PBS • Do we really need Condor for farm batch processing? Who is using it now? • Future dependencies to come: • database and GUI for monitoring (TBD)

  4. Analysis of WP’s: WP4 (II) Dependencies on SW provided by other WP’s • Packaging (SW packaged according to WP4 standards and rules) • vs. Globus GPT and others… • Wider question: what WP’s are mandatory to deploy?? • Service management: provide LCFG component [wrapper] for your services • In the future: R-GMA && WP4 information providers • Changes on the schema? • Changes on the invocation model (push/pull) and output format?

  5. Analysis of WP’s: WP4 (III) Vagueness of responsibilities/ holes in functionality between WP’s • Accounting (at global and local=fabric level). • What info is needed from the fabric? • For what purpose? (authorization, grid banking?) • MPI • Inside a fabric farm • Between fabric farms • Interactive jobs • (not related to WP4…) Management of storage capacity on cluster CPU nodes? • Use local disk space for (unreliable) replicas

  6. Analysis of WP’s: WP4 (IV) Redundancy/duplication of WP’s • Monitoring • Schemata and interface for sensors • Presentation of monitoring data
