Tuesday 2nd May

  • HEPiX took place 24th-28th April.
  • EGI: WMS service decommissioning and transition to DIRAC queries (noted Dirac and T2K).
  • EGI considering the WLCG proposal for adoption in EGI for downtime notifications:
    • a scheduled intervention shorter than 5 days must be declared at least 24 hours in advance
    • a scheduled intervention longer than 5 days must be declared at least 1 month in advance
    • any other intervention that don't fulfill the rules above will be considered unscheduled
  • GOCDB information review. The GridPP tracking table is in the wiki. It relates to GGUS 127588.
  • A reminder that registration for the WLCG ops workshop in Manchester is open.


WLCG Operations Coordination - AgendasWiki Page

Tuesday 9th May

Tuesday 4th April

  • The next ops coordination meeting is this Thursday 6th April. Agenda. The theme is HTCondor accounting work at PIC.
    • Any T1 or T2 issues to be discussed?

Monday 20th March

Monday 6th March

  • There was an ops coordination meeting on Thursday 2nd March - agenda | Minutes.
  • The overview talks were: Mid-SLAs | Machine Job Features.
  • The main summary items:
    • Lessons learned from ATLAS tape usage tests. Follow up via FTS steering group. Will share experience with other experiments.
    • "Mid SLA" resources. During the next months accumulate experience at CERN (providing such resources) and in experiments (using such resources). Review accumulated experience after a couple of months and decide what we need to do in terms of tagging, accounting, etc...
    • MJF deployment is not as successful as desired. Find help (at least temporary) for deployment campaign concentrating on the LHCb sites. See whether this task would become more important considering outcome of the benchmarking discussion.
    • In order to avoid inconsistencies in the naming of the service types along the WLCG IS chain (GocDB, OIM, SAM, experiment-specific systems like Dirac), there will be agreement between representatives from OSG, EGI and GocDB team and IS evolution task force on the policy for introducing of the new service types.
    • The next WLCG ops coordination meeting will be on 6th April.
Tier-1 - Status Page

Tuesday 9th May A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here

  • Atlas now have 1.5PB of data in ECHO
  • The number of batch jobs running in SL6 containers on worker nodes running SL7 is being ramped up. Expect all worker nodes will have this configuration by the time of this meeting.
  • We have dates for the Castor 2.1.16 upgrade. This is hoped to improve performance, particularly in light of the problems seen by LHCb. The proposed dates are: Castor central services (nameserver) and LHCb on Tuesday 9th May. Atlas and CMS instances on Thursday 11th May. The 'GEN' instance will be a couple of weeks later.
  • A week ago on Friday (28th April) there was a problem with the UPS for building R89. The UPS switched itself into "bypass" mode - which effectively means we have no UPS. We have run in this way since then. The cause was overheating of internal capacitors which failed. At the moment costs are being gathered for a way forward. In the current situation the diesel generator cannot be used either.
Storage & Data Management - Agendas/Minutes

Wednesday 19 Apr

  • Case for (re)testing CVMFS for T2s? (and non-LHC VOs?)
  • Other storage related issues arising from use of containers?

Wednesday 12 Apr

  • Musings on the outcome of last week's GridPP meeting
  • Discussion of which of a selection of coming events to aim to do something for. If that makes sense, gramatically.

Wednesday 15 Feb

  • Space tokens! Use them!
  • Leafed through interesting topics (technology permitting) from the CS3 workshop

Wednesday 08 Feb

  • More on accounting (again)
