Round Table

Marco Cl.

  • Gaudi
    • started merging of ROOT 6
    • included hwaf config
    • will attack LHCb
  • Problem in the nightlies with the new libopenssl (in SLC 6.5): builds using that version do not work with the old one (SLC 6.4)
    • agreed to move back the SFT build machines to SLC 6.4
    • we will need to test upgrades in the future
  • Problem with Spirit in Boost 1.55 (gcc48 with C++11), tested in the nightlies in "dev" (lhcb-lcg-head)
    • Reverted to Boost 1.53 until the problem is understood (will ask Sasha to check)

Joel

  • Started to build LHCbGrid for gcc48
  • Will test Python 2.7

Gloria

  • Michel playing with DecFilesTests in lhcb-branches
    • Pythia 8 much slower than Pythia 6
    • we do not really need to build all the platforms for these tests: need for a new slot (no need to install it on AFS)
  • We should have a Core Software Meeting with Alex Grecu to discuss on some development/infrastructure he needs for
  • in 2013 we got a beam position slightly different from 2012, so we need a new Velo position for the simulation

Marco Ca.

  • Stack released up to Brunel (we can start break)
  • Sent to a few people some homework: describe service/development tasks to present to the collaboration board

Illya

  • Ariadne not accessible: configuration broken (overwritten by the wrong template)
    • we need a monitoring (SLS)
  • Another problem with the CondDB connection with the browser: locale issue
    • Locale enforced in CondDBBrowser (as in GaudiPython)
  • Working on GaudiHive

Ben

  • New SVN repository non-public: lhcbint
    • hacked in place on AFS (no need for CVMFS, wait for new LbLogin)
  • CVMFS problem: splitting of the catalogs done in one go by mistake, blocking the system
    • a problem on stratum-0 may block releases for days, unacceptable for Online
    • we need to test version 2.1 of the server (quicker recovery)
    • the current machine is very slow, probably because it uses NFS instead of local disk (to be test)
    • will create tasks and subtasks in JIRA to follow up

Liang

  • Added the enforcing of locale in CondDB scripts
  • Started thinking about the CondDB development for after LS1.
