Monday: Easter Monday holiday

  • The meeting will be held on Tuesday instead.



  • local: Raja, Maarten, Jan, Jerome, Stefan
  • remote: Peter, Xavier, Rolf, Wei-Jen, Oliver, Onno, Lisa, Lucia, Rob, Pepe, Gareth, Jeremy, Roger

Experiments round table:

  • CMS reports (raw view) -
    • LHC / CMS
      • Rereconstruction of 2012 data in the tails, load at the T1 sites small
    • CERN / central services and T0
      • Frontier system under high load over the weekend, FastSim workflow was mis-configured using the FullSim job splitting causing very short jobs with a lot of access to the SQUID caches to access alignment and calibration constants. If you see failures in SAM tests and/or Hammercloud tests because of failed access to Frontier, please open a savannah ticket to get the SiteReadiness calculation corrected.
    • Tier-1:
      • ntr
    • Tier-2:
      • ntr

  • ALICE -
    • NTR
      • Xavier: There was a question from ALICE why jobs were lost last week, the reason was a reboot of the VOBOX
      • Maarten: Yes, was also reported in the WLCG Ops meeting last week, but also after the reboot there were some instabilities seen

  • LHCb reports (raw view) -
    • Mainly user jobs with some MC ongoing.
    • T0:
      • No SAM tests displayed on the SUM dashboard - solved now (GGUS:92924). Solution not very clear though.
    • T1:
      • RAL : Continuing to have occasional problems with setting up job environment.

Sites / Services round table:

  • KIT: today 8.30 am one fileserver showed issues, hardware is currently being replaced, for the moment 6 x 30 TB are not available for ATLAS
  • CNAF: Kernel upgrade is finished. Pledges are available as of today
  • RAL: NTR
  • NL-T1: NTR
  • PIC: Scheduled DT of last week went well, but after coming back online the chimera system was unstable, therefore rolled back to the previous version. Pledges installed as of today.
  • IN2P3: NTR
  • OSG: NTR
  • GridPP: NTR

  • Batch Services: NTR
  • Storage: Announcement: next Monday the "file update functionality" for CASTOR will be removed for ATLAS, CMS and LHCb. ALICE was already running without.
