  1. Status of the production and STEP09 TF meeting June 4, 2009

  2. Production status • Great start of June – long weekends are always productive • Running parasitically on a lot of ‘free’ resources

  3. Running status RAL Jobs drained, change of SE

  4. Running status Jobs drained, change of SE

  5. Issues • The system is becoming too popular for its own good • User analysis is a very popular item • Given the multi-million events available • The issue is with quotas • Job and disk • Minimize the amount of users who loop over the ESDs at the same time – Analysis Train (still to become fully operational)

  6. User job profile Jobs drained, change of SE

  7. SE profiles Jobs drained, change of SE

  8. SE profiles (2) Jobs drained, change of SE

  9. SE profiles (3) Jobs drained, change of SE

  10. SE profiles (4) Jobs drained, change of SE

  11. ALICE activities calendar STEP’09 Cosmics data taking WMS and CREAM CE Reprocessing Pass 2 Analysis train Replication of RAW Data taking RAW deletion 12 01 02 03 04 05 06 07 08 09 10 11 12 2008 2009

  12. ALICE STEP’09 activities • Replication T0->T1 • Planned together with Cosmics data taking, must be moved forward, or • We can repeat the last year’s exercise, same rates (~100MB/sec), same destinations • Re-processing with data recalls from tape at T1 • Highly desirable exercise, the data is already at the T1 MSS storage • Depending on the agreed duration, we can make more data available at the T1s

  13. ALICE STEP’09 activities (2) • Non-Grid, but equally important activity – transfer rate tests (up to 1.25GB/sec) DAQ@P2 to CASTOR • Validation of new CASTOR and xrootd transfer protocol for RAW • Will go on just before or overlap with STEP’09 • Critically dependent on the availability of CASTOR v.2.1.8 • The transfer rate test will be coupled with first pass reco@T0
