• 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.

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)
