  • For remote participation we use the Vidyo system. Instructions can be found here.

General Information

  • The SCOD rota for the next few weeks is at ScodRota
  • General information about the WLCG Service can be accessed from the Operations Web



  • local: Alessandro (ATLAS), Lorena & Maciej (CERN DB), Maarten (ALICE), Maria D. (SCOD), Stefan (LHCb), Tsung-Hsun (ASGC)
  • remote: Christoph (CMS), Michael (BNL), Lisa (FNAL), Rolf (IN2P3), Sang Un? (KISTI), Dimitri (KIT), Ulf (NDGF), Onno (NL_T1), Rob (OSG), Pepe (PIC), Gareth (RAL).

Experiments round table:

  • ATLAS reports (raw view) -
    • CentralService & Tier0/Tier1s & general overview
      • FZK storage issue tracked and discussed in GGUS:110693
      • BNL FTS server in trouble, experts notified.
      • several ATLAS DDM and ProdSys2 issues are affecting the overall production, more details below

  • CMS reports (raw view) -
    • Rather quiet atm (many CMS colleagues are in Miami for the Winter collaboration week)
    • CMS plans some production during Xmas / New Year

  • ALICE - ntr

  • LHCb reports (raw view) -
    • "Legacy Run1 Stripping" campaign running full steam and progressing well, prestaging of input data was restarted + MC and user jobs.
    • T0:
    • T1:
      • CNAF: hiccup with SRM on Friday, fixed promptly
      • RAL: WARNING DT on the week-end went bad, ask sites to declare OUTAGE in case a the site is affected -> automatic handling by Dirac

Sites / Services round table:

  • ASGC: ntr
  • BNL: The transition from USLHCNet to ESnet is complete for the BNL and FNAL T1s and was Very smooth. They now enjoy 40Gbps of dedicated bandwidth out of 340Gbps of the total available. The plan is to also move the LHCONE-ESnet instance to use the ESnet infrastructure for the transatlantic link in January 2015 (120Gbps capacity). Dante and Geant traffic exchange with ESnet will also be able to use this infrastructure then. The South American sites are not part of this change.
  • CNAF: not connected
  • FNAL: Downtime tomorrow 8am-4pm for the dCache upgrade (including bug fixes and performance improvement).
  • GridPP: not connected
  • IN2P3: ntr
  • JINR: not connected
  • KISTI: ntr
  • KIT: ntr
  • NDGF: A transparent 30' downtime will take place on Thu 18/12 at 12hrs noon UTC.
  • NL-T1: ntr
  • OSG: ntr
  • PIC: Now in scheduled downtime for dCache upgrade until 5:30pm CET.
  • RAL: The DNS problem of last Saturday took all day to resolve. Gareth will relay LHCb's observations about changing the Warning status in GOCDB to a Downtime one when an issue takes longer than expected.
  • RRC-KI: not connected
  • TRIUMF: not connected

  • CERN batch and grid services: not present
  • CERN storage services: not present
  • Databases: ntr. ATLAS has a question on hadoop. It should be sent to the CERN/IT/DSS group.
  • GGUS: not present
  • Grid Monitoring: not present
  • MW Officer: not present

Experiments round table:

  • ATLAS reports (raw view) -
    • Daily activity overview:
      • errors overview
      • task req 1239 will be aborted now by Andreu.
      • SCRATCH
      • Really need to restart LOCALGROUPDISK deletion - needs input from Tomas. Cedric/Tomas dump from DQ2. and then we check that all the files h
      • PHYS-TOP request
      • Deletion: FZK?

  • CMS reports (raw view)
    • Quite some work assigned to the Grid sites "Xmas production"

  • ALICE -
    • expectations for the end-of-year break:
      • mostly steady MC production
      • some raw data reprocessing
        • data being staged, no tape activity foreseen during the break
      • low analysis activity

  • LHCb reports (raw view) -
    • "Legacy Run1 Stripping" campaign running full steam and progressing well, prestaging of input data was restarted + MC and user jobs. Note, the stripping campaign will continue over the xmas break.
    • T0:
    • T1:
      • CNAF: some debugging ongoing on mostly SRM protocol access for different kinds of activities to the storage elements, no conclusion/solution yet.
