Experiments Reports

ALICE

• very high activity during the end-of-year break and still ongoing this week
  • our thanks go to the sites for their good performance!
  • 1 team ticket needed to be opened for CERN: cvmfs-alice.cern.ch was down (GGUS:110968)
• ARC CE SAM tests:
  • direct job submission probe needs to be debugged further

ATLAS

CMS

• Production/Processing overview
  • Had some Xmas production
  • Was rather stable and only a few site issues
• Disks at some Tier-1 sites are rather full
  • Needs cleanup from the CMS production side
  • T1_FR_CCIN2P3 has been integrated into Dynamic Data Management during Xmas holidays
    • further Tier-1 centers are being integrated right now: T1_DE_KIT and T1_ES_PIC are next (most urgent)
    • The integration will be coordinated with the CMS site contacts
• 50% of Tier-1 capacity multi-core enabled
  • If site has dedicated multi-core resources, it should provide this fraction
  • Will be partly used in "partitional slot mode" (Running n single-core jobs in n core multi-core pilot)
  • Long lifetime of pilots preferred -- what is still feasible for the sites?
• In progress of moving CRAB and central production into a single global Condor pool
