  • LCG 80 soon

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.



  • 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


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