General News

• ADC and ATLAS Computing News [20140114]
  • ADC Weekly meeting
  • Frontier Conditions Data access issue
    • Heavy load identified on Frontier servers on Jan 9-10. More contained at TRIUMF and BNL.
    • Problem on Oracle level where response time was 500x slower
    • http://savannah.cern.ch/bugs/?103602
    • Full table scans over 100GB, probably related to updated COOL relying on Oracle 12 feature but running 11
    • Full cause still being investigated. Some load from new overlays for DC14 but is that all?
    • During this identified that ATLAS CERN squids are not under central IT services for monitoring
  • MC production status
    • Standard production
      • Large backlog of mc10-12, single core, expected to ramp down in next few months
      • Switch mc12 to multicore after feedback from large scale production tests
    • DC14 8TeV
      • Most s/w and brokerage issues resolved
      • sim on multicore, digi+reco in March (TBD: single or multicore)
    • Multicore resources share for MC and DC under discussion
    • High Memory Queues
      • ATLAS+IBL production need 6GB, about 45M events, 5M partly done
      • Max RAM in AGIS not always reflecting site policy
      • Binding tasks to high-memory queues in US (SLAC, BNL)
      • ND Cloud settings in AGIS better - allows correct brokerage
      • As other sites provide MCP slots and AGIS corrected can change brokering
      • Expect ~1 month (SLAC 1k, BNL 2k, ND 1k + additional as become available)
  • Reprocessing status
    • DESD RPVLL/CP
      • Reprocessing of all 2012 data for Egamma, Muons and JetTauEtmiss streams
      • Filtered (~2%)
      • Slice test completed in December - completing validation
  • DDM: overview of primary data
    • DQ2 ops is working on re-balancing primaries in T1 DATADISK according to MoU share
    • TRIUMF MOU: 9, current share: 10 - dropped from 7.5% in Jan 2013 to 6.3% now.
    • Primary datasets take up ~65-85% (average: ~74%)
    • DQ2 ops would like to keep primary lower => discussion with CREM about replication policies
