  • Fermilab Annual Meetings on Manycores
  • Software Week in two weeks time (computing session Tuesday afternoon)

Round Table

Marco Clemencic

  • Prepared a proof-of-concept implementation of nightly builds replacement driven by Jenkins and CDash
    • stability depends on the subsystems (AFS, etc.), but the monitoring and control is much better
    • CDash is not as good/nice as expected, but the old summaries can be used instead
    • QMTest integration with CDash is possible (easy): a few days of work
    • (if we want to keep old summary page) the old build log web pages need to be rewritten
    • installation on AFS not yet implemented to avoid interference, but easy to achieve
    • feedback and manpower allocation needed

Rob, Marco Ca.: we need a dashboard and links that we can send to people, but the layout can be different.

Ben

  • SLC6: effort in SFT to produce the RPM with the list of dependencies
    • segfault on i686 under investigation

Discussion about i686 support: starting from next Gaudi we can stop releasing i686.

New project: Urania containing parts of Erasmus, depending only on ROOT.

Marco Ca.

  • We should systematically deploy software to the Online. We should also remove the option from savannah.

Illya

  • Focusing on the finalization of the Compatibility Tracking Tools

Marco Ca.: There is a discussion ongoing on the concept of Data Type

  • the plan is to split the concept in a Detector Type and Reco Type

Gloria

  • Need to define 2 new file types: what should be changed in ProdConf?
    Rob: you need to change IOHelper too
  • Ben set up a new package to host the scripts to obtain the MC production statistics (generator and filter). To avoid problems for it release and distribution it has been put in DBASE
  • A new data package will be needed Det/GDMLData. This will host gdml description of the RF foils for studies and will allow to produce events with them centrally. This package is only for Gauss
  • Gauss and gcc46: one left over compilation problem in the generation of Configurables of GiGaCnv. Marco Cl. tracked it to Gaudi and put fix in svn. Will see result of gaudi-head slot in today nighlty (not ready yet). Marco Cl.: still failing, under investigation
  • Trying to move the generator statistics in the XML Summary.

Rob

  • Somebody in NIKHEF working on GPU optimization of tracking software.

Suggested to have a GPU-related development forum, but the convener is missing.
