Round Table

Marco Cl.

  • Gaudi
    • working for the merge with Atlas: new checkpoint release either this week or soon after the workshop
  • ROOT 6
    • 3 categories of failures:
      • PyAlg (GaudiPython/Bender)
      • Python bindings for interactivity
      • aida2root, where the content of the histograms is different between ROOT 5 and 6
    • the aida2root problem will be investigate with high priority, but the other can be considered non-blocker for ROOT 6 beta.


  • Ariadne
    • Neo4j upgraded to the latest version
    • working on a new mechanism to enable security for adding data, but it's non-trivial because of the others services on buildlhcb


  • Progress on the CondDB JIRA project.
    • the workflow seems good enough
    • the problems is more the mapping of the fields between Savannah and JIRA


  • Finally decided how to use Ariadne for Moore
    • for the versions used in the PIT must be compatible with the data type etc. they were used for
    • other versions should not be compatible with anything

Gloria: do not forget the compatibilities needed for simulation.

  • Problem with Application projects that use different top level configurables (now Moore does have the Moore application and the L0App application) and ProdConf.

We had a longish discussion about the role of ProdConf and how to proceed. The discussion will be resumed at the workshop.


  • A few releases of new generators announced by GENSER people and it would be nice to be able to test them in the nightlies without having to commit changes to SVN.

Marco Cl.: it can be done, but we need to discuss the details offline.


  • There are several AppConfig files to set the TCK in different context: it should be simplified.

Marco Cl. will check with Federico how the TCK is set and translate the current set of TCK-setting files in ProdConf code.
