LHCb Core Software Meeting

Date and Location

10:30 - 12:20
CERN (2-R-030)


Ben Couturier, Bram Bouwens (Vidyo), Illya Shapoval, Joel Closier, Marco Cattaneo, Marco Clemencic (minutes), Rob LAmbert (Vidyo), Stefan Lohn



  • Introduction of Bram
    • Marco Cl.: it would be nice to have a detailed presentation of the optimization work; in the clean up you should keep an eye on multi-treading anti-patterns
    • Ben: do we have unit tests for the functors? if not, they should be added
  • LCGCMT 66 plan: gcc46 platforms to be enabled in the slot 'dev', for testing; if it's OK they can tag.
  • ROOT 6 meeting in the afternoon
  • Joel: all grid middleware have Python binding for Python 2.7

Introduction on Ariadne (Illya)


Round Table

Marco Cl.

  • ROOT 6
    • Danilo managed to compile Gaudi with ROOT 6, which seems to work except for the Python bindings (bug reported)

    • Work-around for the problem of CTest when building Geant4 reported last week.
    • Still to enable CMT-compatibility of Geant4 CMake build
  • Gaudi
    • Added two algorithms to defer the writing to file in the Stripping use-case (needed for DaVinci+GaudiMP) task #47619, but need validation before release
    • Extended gaudirun.py to accept a .qmt file as argument: it is replaced on the command line by the arguments and options it contains
    • adding support for clang static analyzer


  • Added the possibility of producing CTest-compatible XML output from QMTest and from Python Nose
  • Prepared a script to parse the CTest XML and produce a summary page similar to the current one, with some improvements.
    • grouping
    • direct link to tests
    • navigation
  • Working to introduce the RSS functionality to the new Nightly Builds dashboard.


  • Working on the control flow machinery of GaudiHive

Marco Ca.

  • Doct/Tech student board approach
  • Ben is going to organize reharsals for CHEP.


  • Created a test instance of LHCbPR at http://cern.ch/test-lhcb-pr
  • Adding support for Valgrind an Massif to LHCbPR (can be run from Jenkins)
  • Added support for icc 13 in LbLogin (as it was for icc 11)


  • Testing the support for igprof in LHCbPR


  • Nightlies Dashboard incredibly slow
  • Problem with messages of "vector already included" (similar to the one reported by Vanya)
  • Thinking about a new project (MooreOnline) to bind Moore and Online for testing.
  • ideas about new tools (discussed privately with Ben)
  • it would be nice that getpack could use by default anonymous access (faster)
