Round Table

Marco Cl.

  • Fixed CondDBCompression issue with Stripping applications (LBCORE-238)
  • Nightly Builds
    • Restored "headofeverything" feature (LBCORE-240)
    • We can build releases with the nightly build system, but we need to validate the products: how to do it?
  • ROOT 6 Test Status
    • Reflex Plugin service replaced with a ROOT-free one, tested in the nightlies
    • Testing new genreflex but there are unrelated problems with genconf (segfault in a destructor in ROOT)
  • CMake
    • Trying to build Geant4 with CMake in the nightlies, but, it seems, there is a problem with CTest.

Marco Ca.: request for new stack soon; are there changes in Gaudi? not really


  • DIrac is using the the same Jenkins ash the nightlies.
  • We may have a new project for the Virtual infrastructure: BeautyDirac
  • We need to reboot SLC5 build machines to upgrade the OS


  • Problem with mmapped deleted temporary files, probably due to SQLite.
    Marco Cl. will follow it up with Markus.


  • What is the status of the changes in the notification policies in JIRA?
    Ben will check.
  • Decoupling of the Generators : LHAPDF now moved to a data package.
  • We need to feed back to SFT some interface packages (will be sent to Benedikt and Victor).


  • New web application for the radiation maps.
    • old app written in C++ that took a bit to compile (strong requirements on ROOT and Boost versions)
      Gloria: we should draft recommendations for web applications
  • Working to integrate Valgrind and Massif in LHCbPR
  • Issue with ICC13: LbLogin -c does not set up the environment correctly
  • We should drop gcc47 and move directly to gcc48; to check with SFT, but we can do it in the next stack.


  • Many changes to LHCbPR to be deployed.
    Ben: we should push them to the dev instance.


  • Testing the JIRA configuration for CondDB patches.
