    • gcc 4.8 will be added, but can we drop gcc 4.3? not yet, Gauss being validated on gcc46, they shoud drop i686 first
  • AF tomorrow
    • Grid middleware: new FTS3 depends on Boost, but there are problem integrating with LCG externals (for LIM)
  • Summer students
    • Joel, Marco Cl., plus a non-member state on the Masterclass project (more physics than computing)
  • Marco Ca.: request feed back
  • Illya: workshop at Desy on GPUs etc.
  • Joel: meeting two weeks ago about Oracle and the new licensing policies
    • discussion about the possibility of moving applications away from Oracle

    • improved (take the list of platforms from the configuration file)
    • failure this morning because of a typo (fixed and restarted)
    • planning for production
  • LBCORE-24: build nightlies on CVMFS, problem with Gauss + Genser

Marco Ca.: Coverity nightly seems not to have worked. Check and add an alarm.



  • Working with VTune profiling of Gaudi
  • Adding handler for memory and VTune in LHCbPR
  • Testinf new compiler, but volhcb34 needs to be moved to slc6

--++ Marco Ca.

  • Philippe has been migrating files from CASTOR to EOS, including files required by QMTest tests.
    • Philippe will create a special space token to decouple special files from the production sets (so that they are not deleted when cleaning up)
    • We should have a special private file catalog for testing in PRConfig (Marco Ca. will do it).


  • Attempt of a fix for Gauss hanging.
  • Emmanouil is going to leave at the end of the month, so he should present the work at the Core software meeting.


  • CondDB new web portal in production.
  • Will need a new SQLDDDB for the portal and for the deployment system.
  • Several improvements in the Ariadne system
    • Apache will shield both Jenkins and Neo4J (administration and command line administration), will tell Joel to add the configuration to the template
    • XML-RPC interface to the Neo4J to have world readable queries.
    • Implemented user access to Neo4J in CondDB package


  • Some updates to CondDBUI to support compressed database. Almost ready for production.
