Joel

  • Created virtual machine with 500GB of disc,
  • LHCbDirac ready to move to Python 2.7
    • still issues with the way middleware libs are built (problems with the externals)
  • PID Calibration required disc space to store ~100 GB of calibration data. They asked for AFS, but they will get a storage element (EOS space).

Illya

  • The shutdown of Neo4J was not a clean one, triggering a bug in Neo4J that caused the explosion of the number of entities. In any case there was no corruption.

Gloria

  • G4 examples are needed to run regularly tests to be published to LHCbPR.
  • Next week there is the LPCC workshop.
    • Paul will present our plans for Geant4 10 and multithreading
  • Marco Cl.: added handling of platform-independent generated files in the nightlies (only for Geant4 and DecFiles)

Ben

  • Provided Benedikt with a script to generate the RPMs we can install. Being tested.
  • Working on the packaging as RPMs of our projects.
  • Testing of CVMFS server is going well:
    • it nicely handled disc full
    • we need a garbage collection on stratum-0, to remove the history (developers are working on it)
    • we should move to production for the nightly builds installation
