  • Meeting about the CERN Content Management System (CMS) service the 3rd of August

Round Table

Marco Cl.

  • Would like to understand better the position of LHCb on Neurobayes (to correctly report it at the A.F.)
    • Not yet defined: we must have a usable (and distributable) installation to be able to evaluate it
  • Gaudi is ready for tagging, waiting for LCGCMT.


  • With the new nightly build system, we have to define the order in which the slots/platform are built.

Marco Ca.:

  • Reshuffle of the LCG slots.
    • Karol will adapt the configuration
  • Problem with the lhcb-lcg-head slot: complete failure (missing input?)
  • Windows not working in lhcb-head (missing local copy of the externals)


  • Problem with lxbuild157 2 days ago (lost contact), rebooted.
    Marco Ca.: Karol should be made aware of these issues
  • Prepared a script to monitor the space in project volumes. It sends an e-mail to the e-group lhcb-afs-admins.


  • Rolling Compat including libunwind
    • to be removed as soon as not needed anymore (i.e. when LCGCMT 58a is archived)
  • Contacted by Axel to install our software on the machines that will be used with Coverity.
  • Atlas is moving to Python 2.6 (LCGCMT 59). When do we do it? What do we need?
    • We need the bindings for the grid middleware
    • Python 2.6 requires VC >= 9, we need lhcbts02 configured to be able to test it.


  • Working on the extension of the TagCollector web pages.
    • Needs a pysvn usable on the web servers (complicated to set up).


  • Needs the specifications for the DQ flags.
    • Check with Marco Adinolfi
