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.
