Marco Ca.: what's the status of LoKi caches? Some changes required from Vanya (predictable number/name of output .cpp files). If not ready by the end of CHEP, Marco Cl. will do it.


  • We need to retire the SLC5 machines and a few SLC6 machines.
    • one is the Coverity machine
    • issue with connecting to SLC5 VM for the nightly builds
    • lxbuild119 will stay until the end 2015
  • Discussion with SFT to have middleware libraries for gcc49

At LIM it was discussed a possible approach to provide grid middleware builds to the experiment. A proposal will be circulated.

Marco Cl.

  • In the SFT group meeting there was a presentation about AIDA, mentioning GaudiHive and contributions from LAL.
  • Beat would like to have the latest CondDBUI version.


  • What's the status of CLHEP 2?
    • Marco Cl.: at the LIM it was mentioned that RELAX does not build (Pere investigating, Marco Cl. would like to have a look)


  • Could not find a recent build of cx_oracle in cvmfs (probably looking in the wrong place).
    • Ben found the recent one


  • Trying to compile Geant4 10
  • We need to finalize the new deployment procedure.


  • Patched catalog files in LHCBCOND to use alignments from the ONLINE partitions. Deploying it.
