Date and Location

10:30 - 11:15
CERN (2-R-030)


Illya Shapoval, Joel Closier, Marco Cattaneo, Marco Clemencic (minutes), Markus Frank



  • LIM
    • discussion on the new installation scheme: to be confirmed by ATLAS, but we will get something similar with what is already there (possibly with some kind of optional InstallArea)
  • ITUM on Monday

Discussion about GIT support in LHCb: we are not going to support GIT for analysis.

Round Table


  • Asked LCG people to get bindings for Python 2.7 for the middleware, but the question is if we need them for SLC5 and/or SLC6.
    • we will need both as long as we have SLC5 resources on the Grid
  • Received instructions to set-up Tivoli backup on lxbuild119 (buildlhcb).

Marco Cl.

  • Nightlies
    • machine occupation improved after the tuning discussed at last meeting
    • improvements to the new dashboard ([http://lbtestbuild.cern.ch/nightlies/]), some more work needed, but it could be put in production soon
  • ROOT 6 preparation
    • managed to run Gaudi and LHCb tests without PyCintex (using PyROOT instead), but it requires some hacks that should be implemented in ROOT (Wim is working on it)


  • Ariadne update, see LBCORE-28.
  • Added a TOOLS package to distribute the Ariadne code and prepare the environment for the Python modules. A wrapper will be added to LbScripts to simplify the access to the tools.
  • Waiting for a confirmation from Gloria to start the switch.

Marco Ca.

  • Chris has been fighting against a dictionary generation problem (reported on Savannah).
    • We need a test to write/read every event model class, which will help in the validation of ROOT 6.


  • New release of Online: Markus testing versions. It should not be picked up by subdetectors.
