Round Table

Marco Cl.

• Some new projects in Git
  • LHCbGrid (official repository moved to git)
  • Geant4
  • Gauss
  • preparing Geant4-srcs to mirror Geant4 official sources and host our patches
• Gaudi v26r4
  • package tags missing in SVN (to be added)
  • new release procedure: release notes from JIRA and Git, but because of the transition they are not exhaustive
• Would like to move the nightly configuration repository to gitlab
  • allow authentication via SSO (e.g. delegating to lhcbsoft for the commits, preserving the author)
  • quick fixes possible from the web interface
  • requires some work (a JIRA ticket will be open soon)

Marco Ca.

• Started releasing new stack on top Gaudi v26r4.

Ben

• Working on compilation of our stack on clang 3.7
  • no clang 3.7 LCG stack
  • slot built in the nightlies to test it (https://buildlhcb.cern.ch/nightlies/?slot=lhcb-clang-test)
• Working on a CMT-free environment for login/runtime
  • well progressing, but still bits missing
• Stefan started discussion on monitoring, that will have to be followed up
• People suggested (again) to have a stackoverflow-like tool for Q&A.
  • prepared a test instance of "questions2answers": https://test-lhcbqa.web.cern.ch/test-lhcbqa/question2answer/

Illya

• Planning to move Ariadne from buildlhcb to a new (virtual) machine
  • we need to check that the migration (downtime) is not affecting too much the users (e.g. automatic release build)
• Worked some years ago a monitoring system for the CondDB, which should be integrated in the agreed monitoring system

Joel

• lxbuild119 (buildlhcb) should be retired tomorrow, but we have time until the 15th of November.
  • 3 new VMs created for CouchDB, Jenkins and Neo4J
