  • Some physical machines (mainly SLC5) have to be retired
    • lxbuild159 is used for Neo4J test instance, but it can be moved to a VM
    • we should try to use the VMs only for the minimum required time
    • one possible candidate to work on Jenkins
    • somebody to convert Dirac build to pip
    • Ben preselected 3 CVs
  • Linux certification meeting
    • they understood that they have to decouple the OS from the experiments: they do their migrations and we do it at our pace
    • complaints about lxplus being slow

Round Table

Marco Cl.

  • CMake
    • some improvements
    • fixed a few projects (Online, Urania, Geant4)

    • integrated the builds of LHCbDirac and Dirac
    • we need to reorganize the slots

  • Marco Ca.: we need to completed the commissioning of the conddb system after the test run (including remove the redundant Oracle instance)


  • Fixed mkLCGCMTtar from RPM
  • We need to check (and fix) the RPMs of LHCbDirac and Dirac
  • Problem with SFT: they provide RPMs only for what they build, but we need others too
    • prepared a script to package anything that is in sw/lcg
  • Improved/fixed lb-sdb-importsvn, still to automatically flag new projects for release
  • Required to prepare debug RPMs and tar files for externals
  • Working only running Hlt and publish infos to LHCbPR
