CERN (2-R-030)


Anastasia Karachaliou, Ben Couturier, Gerhard Raven (Vidyo), Gloria Corti, Illya Shapoval, Joel Closier, Liang Sun, Marco Cattaneo, Marco Clemencic (minutes), Markus Frank, Roel Aaji, Sebastien Binet (Vidyo), Vanya Belyaev



  • Gaudi v26r0 released as well as the stack up to DaVinci
  • HSF Workshop next week
  • LIM
    • Requested Eigen and GTest in the externals
    • SFT working on a massive upgrade
    • Benedikt proposed to contribute the packaging system to HSF
  • ITUM this afternoon
  • Call for summer students: to be reported to Andreas by the end of next week.
  • Joel: two build machines unreachable yesterday morning because of failed power supply
  • Marco Ca.: Tim Head would like to organize a tutorial for software carpentry

Gerhard: can we have clang builds in the nightlies?

  • Ben: we have been asking SFT
  • Marco Cl.: we could try to build our nightlies with clang on top of gcc48

Gerhard: it would be great to have the clang tools available to everybody.

  • Ben & Marco Cl.: this is unrelated to have the nightly built on clang

Round Table

Marco Cl.

  • Gaudi: replacement for QMTest on its way


  • Hlt and Moore releases took long (CMake and ROOT problems)
  • ROOT bug reported but not top priority because we have a work around
  • Phys required a new build
  • Gerhard changes made Moore go faster (25% more throughput)

Marco Ca.: we need to check the memory usage with ROOT 6


  • Issues with the deployment of Gauss because of data packages that do not have the RPMs
  • The RPM of Geant4 was missing the InstallArea/include directory. Fixed by Marco Cl. moving it to InstallArea/include
  • Problem with AlpGen and "make -j" because of several libraries using the same source file
  • Problem with AlpGen and CMake (sources not found)
  • Has to add LCG to the lhcb-head configuration


  • Since 2 weeks we are using the new tools to build and release Dirac/LHCbDirac
  • Problem in the html files used for the dependencies of LHCbGrid
  • The database for Coverity is now available. Marco Cl. will migrate the old database.

Marco Ca.

  • Updating the Computing Task document. Should be finished before the LHCb Week


  • Struggling with the release of Online.
  • Need the fixes in the CMake configuration system


  • Various updated to the DBs
  • Testing the migration of constants from LHCBCOND to ONLINE


  • Manages to build C++ images of all functors in Stripping
  • Need solutions for
    • actual factory calls
    • replace std::hash with something else
    • automatize the builds
  • Changed a lot in LoKi infrastructure (removed several virtual function calls)
  • Testing the C++ functors for Hlt


  • Closed all lbpkr issues
    • handling of data packages versions
    • easily add nightly RPM repositories
