Subjects

News

  • Architects' Forum on Thursday
    • issue with Coverity
  • Technical Student dead-line
    • we need to review the list of candidates (overlaps between the two projects)
  • ISIMA
    • we still have a bit of time to submit projects (Federico and Ben already prepared one, Marco Cl. will prepare another)
  • Marco Ca. on status of manpower
    • we have currently two fellows (on LHCbDirac) and we will most probably have two technical students (on Core Software), and probably it will be like that for the future too
  • Rob joined the software release managers and there is another person that is going to join.

Round Table

Marco Cl.

  • CMake migration status LBCORE-174
    • More projects migrated: Online, Hlt, Alignment, Panoptes, DecFilesTests (to be validated with the tests)
    • Pending: Moore (patch ready), Bender, Panoramix, Erasmus, Urania
  • Nightlies
    • buildlhcb seem
    • Sasha Mazurov found that the Boost Spirit problem with Clang 3.3 and with Boost 1.55 (gcc48) can be solved by a preprocessor macro (change the version of Pheonix). Unfortunately this broke the compilation of LHCb, but Sasha suggested a small change that needs to be tested.
  • ROOT 6 migration
    • not much happened since Christmas
    • removed a few workaround from Gaudi (one still present in Gaudi and one in LHCb)
    • a few showstoppers are still present
    • ROOT 6 planning meeting in the afternoon

Joel

  • Machines
    • recycled a VO-box to be used as a CVMFS stratum 0
    • we can migrate some build machines to SLC6
      • agree to move lxbuild171 and lxbuild172 to SLC6
      • we will need, at some point, to move to puppet (VMs)
  • SLC6-gcc48 version of Dirac will be released next week
    • Ben: Ganga people said they can follow quickly
  • CERN finally joined "eduroam"

Markus

  • Working to fix CMake builds/tests.
  • Issue with CMake warnings.
    Marco Cl.: they can be fixed.

Gloria

  • New head of the simulation projects: Federico Carminati
  • HepMC workshop next week. Will circulate informations.
  • Meeting this afternoon to prepare LPCC workshop on detector simulation.
    • there should be some discussion on multi-processing/threading in simulation
  • GENSER developers are preparing new version
    • we need to be able to test them in the nightlies as we are doing for Geant4 (will discuss with Marco Cl. next week)
  • Working on validation of Gauss on gcc48.

Ben

  • Request from Gerhard for Clang 3.4, both for the compiler and for the tools
    • Marco Cl.
  • Preparation for gcc48 (externals, contribs, etc)
    • we need to extend the version name scheme before releaseing LbScripts
  • Preparing with Joel an CVMFS stratum 0 for testing
  • Velo people asked for a review of their upgrade code
  • Have been working on the support for "periodic" tests (weekly, monthly, ...)
    • issues:
      • Gaudi QMTest can run a user specified test suite, but it falls back on the default if missing (to be changed)
      • the dashboard does not support yet the new tests
    • we should be able to run LHCbPR jobs with this framework next week

Liang

  • Few tags before Christmas.
