News

  • New Technical Student: Victoria Santiago Alcala
    • improvement of the Nightly Build reports
  • Need For Speed next week (no Core Software Meeting)
  • Marco Ca.:we need to organize reharsals for CHEP
    • agreed to have presentations and posters ready by 22nd of March

LHCb PR v2 (presentation by Sasha Mazurov)

The first version is a good tool, but some issues had to be addressed (e.g. simplify work for developers of analysis).

Marco Cl.: which authentication for the REST API?
We can have different authentication mechanisms (e.g. Shibboleth for web and keys for REST)

Joel: we need to use CERN provided tools when we go in production

Marco Cl: migration of the DB?
The new schema is slightly different from the old one so we need to copy the data.

Round Table

Marco Cl.

  • Gaudi
    • minor fixes
    • merged v26r1 on dev/hive (the other way around is much more complicated)
    • few patches/bug fixes pending, to be addressed soon
  • Nightly Builds
    • rewriting the core logic (LBCORE-110, LBCORE-420), first step towards several other improvements and fixes
  • Working a bit on LBCORE-729 (GIT mirrors of LHCb projects)
    • prepared a script to create a initial git repository with all tags of a project, just as a starting point
    • prepared a script to bind the git repository to the trunk on svn (using git-svn), clean up of trunk may be needed
    • minor details to be sorted out before commissioning
    • Marco Ca.: we should prepare a prototype to collect feed back

Markus

  • Preparing a new Online this week.

Illya

  • Completed the work on concurrency control in GaudiHive (presented at the Concurrency Forum)
  • Starting work on GPU integration in GaudiHive

Gloria

  • Used particle gun in Gauss to analyze correlations in random number generator (presented yesterday), probably not really affecting our physics simulation.
  • Testing a new/better random generator.

It's time to migrate to CLHEP 2 (create a JIRA ticket for the task).

Marco Ca.

  • Stack ready to be releases

Liang

  • Added Erschell detector to CondDB for tests.
  • Updating CondDBUI tools for split Hlt support.

Ben

  • CernVM User Workshop tomorrow.
