Gregoire Astruc, Illya Shapoval, Marco Cattaneo, Marco Clemencic (minutes), Martin Plajner, Thomas Hartmann (EVO)



  • Abstract about CMake configuration for Gaudi accepted for a poster at ACAT
  • Discussion with Atlas about future of CMT
    • Small meeting between the most involved people in LHCb and Atlas (including Christian Arnault). A small working group is being set up with the aim of preparing a CMake-based alternative to CMT.
      Marco Ca.: we need to have something production-level by the end of next year to attempt a migration during the long shutdown.
      Marco Cl.: that is actually the proposed time scale.

Round Table

Marco Cl.

  • Problem in the nightlies based on Gaudi HEAD because of the new Job Options Parser.

Marco Ca.: few things to be addressed to prepare for the release of Gaudi


  • Completed current task.
  • Preparing the tools to operate on the environment description.

Marco Ca.

  • LHCb tagged
    • includes work by Rob and others to speed up the Stripping
  • Going on with the validation of the new ROOT persistency


  • Translating the LHCb basic tutorials to Eclipse
  • Feedback needed
    • we need that somebody checks the tutorial pages (we have a candidate) *once Marco Cl. updates the shared installation, we can ask the Core Software to try to use it


  • There's a problem with the connection to the IN2P3 Oracle replica of the CondDB, probably due the a wrong password used in the restoration after a hardware failure.


  • Problems after the change of password for the lhcbsoft account
    • compiled a list of places where the password is required
  • Delays in the nightlies last week because of problems in the test of LCG nightlies (COOL + MySQL)
  • Still working to use the new implementation of the LCG nightlies.
  • Problems with lhcbts04
    • not understood yet
    • Marco Ca.: while the problem is investigated, it is better to sacrifice the slot lhcb-prerelease.
