Round Table

Marco Cl.

• Jenkins / Nightly Builds
  • moved git repository to gitlab (LBCORE-829)
  • upgraded server and plugins
  • re-organization of Jenkins' jobs
  • added priority lane for release jobs
• An ATLAS developer will help testing Gaudi for ATLAS
• Issue with Beat's script to push alignments and calibrations to Offline CondDB fixed yesterday, but there is another issue to be fixed (affecting a very improbable corner case)

Illya: checked the CondDB deployment. Yesterday there was a burst of updates.
Marco Cl. Beat added several runs in one go, after the fix.

Marco Cl.: Joel, can we access http://eoslhcb.cern.ch form outside CERN? If so, we should move the CondDB deployment files to EOS (instead of WEBAFS).

Marco Ca.

• Issue with LoKi dictionaries still present (lhcb-lcg-head used LCG 77 instead of dev4)
  • Marco Cl.: the issue was fixed yesterday, but I forgot that I changed lhcb-lcg-head. Will be fixed ASAP.
• Issue with a test in DetCond to be checked by Marco Cl.
• Strange problem with Muon calibration in Brunel tests
  • Marco Cl.: there was a retroactive change in a (new) L0MUON condition which should not affect the
  • Marco Ca.: is this change logged somewhere? NO. Can we know what changed in the new calibration conditions? In principle yes, but we need to introduce (automatic) tags to simplify the checks.

Gloria

• Problem with permission scheme used by LHCb Simulation: it seems that it was changed. Ben is following up.

Illya

• Increased the frequency of CondDB deployment cron. It cannot be reduced more than that (it currently takes ~7-8 minutes).
• Ben modified the deployment of CondDB to CVMFS to avoid empty transactions and increased the frequency too.
• Ariadne
  • moving to gitlab.cern.ch
  • introduce new type of node to track compatibility on Event Data Format
