LHCb Core Software Meeting

Date and Location

14 February 2007
10:30 - 12:00
CERN (2-R-030)


Florence, Hubert, Marco Ca., Marco Cl. (minutes), Markus, Philippe, Thomas





  • From Architects Forum (Philippe):
    • Oliver Keeble from Grid Deployment (GD) area will be the link-person between the AA and the GD
    • Pere is new leader of SFT and Stefan is new leader of SPI (replaces Andreas)
    • Grid UI software is being migrated to SLC4

Marco Ca.: there is a new version of ROOT released, do we need it? The changes are not needed for LHCb: we do not need to wait a new version of LCG to release Gaudi.

Software Releases

Gaudi (Hubert)

  • Pathces
    • from Atlas (genconf, ICounterSvcm, memory leak in IIncidentSvc)
    • from Vanya (Auditors can use Tools, TimingAuditor)
      Marco Ca. suggests that probably we do not need anymore the code to do the timing in the sequencer. To be verified.
    • Fix for Exception handling: now the default behavior is to stop on unhandled exceptions.
  • We can release on LCG 50

Marco Cl.: what about the plan of the python install area? Not yet ready.

LHCb, Boole, Brunel (Marco Ca.)

  • New release on Tuesday (mainly for Moore)
  • Added MDF package to LHCb
  • Doxygen failing with disk access problems
    • removed references to ROOT TAGS
    • modified the script to generate the documentation so the it can write to a local disk
  • The build using nightlies fails (CondDB change in API)
  • HLT Python dictionary moved to HLTBase

Warning, important The new versions of LHCb, etc. are DC06 compatible, but will never used in production.

Gauss (Gloria)

  • Gauss v25r8 released on Friday
  • Preparing v30r1
    • new Gaudi
    • new GEANT4
    • new generators

Panoramix (Thomas for Guy)

  • Problems with Python
  • Porting to QT4, fighting with ROOT

Round Table

Marco Ca.
Problem with rootmap files: when the dictionary for a class is found on many libraries, it seems that the last one is taken (opposite behavior wrt the one expected for LD_LIBRARY_PATH)
