    • GridKA: Andreas
    • FNAL: Eric
    • NDGF: Olli
    • BNL: Carlos, Iris

  • CERN:
    • 3D: Dirk, Zbigniew, Marcin, Eva
    • ATLAS: Gancho
    • CORAL: Radovan
    • LHCB: Marco
    • Taiwan: Dave

  • Summary from the workshop @SARA
    • Slides are availble on the agenda
    • Dirk will send the slides by email

  • Sites status:
    • RAL: nothing to report
    • SARA: datafile restored from the backup because Oracle produced one error while trying to truncate a tablespace. Attempt to move RMAN logfiles to ASM unsuccesfully.
    • PIC: planing for the second cluster - to be installed next week
    • NDGF (Olli): first streams tests - LCRs rate: aprox. 2000 LCRs per second
    • GridKA (Andreas): nothing to report
    • BNL (Carlos and Iris): working on the new installation. As soon as the database is up, Eva will run the throughput tests.
    • Triumf: running more Streams tests and optimizations
    • Taiwan: investigating the differences between the iperf tests
    • IN2P3: high CPU consumption, around 100%, reported a problem with FTS application, running in the same cluster as LHCb and ATLAS

  • Experiments reports:
    • ATLAS (Gancho):
      • problem with filter rules and grant privileges operations has been fixed
      • tests moving the rule from the capture process to the propagation process have demonstrated that there is no perfromance problems
      • meeting to prepare ATLAS production using Streams
        • accounts creation: Luca will review the scripts to create de accounts)
        • Gancho and Richard has to prepared the tables, exports and imports, rules, ...
        • PSS2COOL application: to be tested on Monday and Tuesday using INTR

    • LHCB (Marco):
      • Software is not ready to go in production 1st April
      • Test on the lhcb downstream archived log mode still to be done (interrupted due to the firewall intervention)
      • LHCb@CNAF performance tests accessing the database to be started next week (keep Eva in the loop)
      • Sites to be joined to LFC: IN2P3 has been proposed but necessary to check first the CPU performance problems (ask them to increase the resources).
