• ITUM 8th of October

Round Table

Liang

• Applied Rich updates to CondDB, but not yet deployed them.

Marco Cl.

• Trying to upgrade Coverity: first failure, trying another
• CMake configuration
  • several improvements in the EnvConfig tool, now almost ready for production (checking with Ben to use it in LbScripts).
  • still improving the automatic translation (environment and data packages)
  • testing the integration with LHCb development environment (in a sandbox)
  • feedback needed:
    • getpack integration: where to put the list of packages and versions?
    • data packages: where to declare the dependencies?
    • runtime: how to define runtime-only dependencies?
• Use of -pedantic during compilation: it is not used in LHCb. Can we enable it? We will get more warnings and some packages do not compile, but fixes are easy.
  • prepare a special slot for testing (check with Thomas)

Joel

• Requested the new 3 machines.
• CVMFS available on the build machines.
• Started to use JIRA for LHCbDirac: https://its.cern.ch/jira/browse/LHCBDIRAC

Ben

• Working for profiling for IT in collaboration with OpenLab
  • provided simple scripts to run
• GENSER: a lot of packages now available for SLC5 gcc46 (only few missing)
• New LbScripts in dev
  • testing install_project, but it was not done in the same way as Dirac, so trying to reproduce the actual use cases
• We were thinking of building the nightlies against CVMFS, but it will break for users running
• It would be very good to have, for each project, the platforms that have been built. Discussing with Marco Cl. to have the information somewhere in the release, e.g. in a special comment in the requirements of the project.
  After some discussion, we agreed to think a bit more about the implementation, keeping in mind a few constraints and requirements:
  • we cannot rely on the project managers to fill the information on their own
  • some sort of inheritance should be possible (e.g. pick up the list from the used projects and redefine only to restrict it)
  • probably we need the list to be produced during the build (may be in addition to the declared one)

Marco Ca. (on LbScripts release): please, check the default size of the release volumes, because they are still not big enough.

Markus (on supported platforms): We should have debug symbols for releases (in separate files). To be followed up (Hubert started some work on it).

Gloria

• Sajan is learning how to apply CondDB updates for Upgrade.
• Investigating how to choose the list of detectors to be enabled for Upgrade studies.
  • Illya will provide a function that at config time returns the data types associated to a global tag.
• Still problems with the nightlies: will report to Thomas (and Marco Cl. in CC).
• Lot of messages printed by gaudirun: is it possible to tune the verbosity (--debug/--verbose)?
  Marco Cl.: most probably not, but to be checked

Illya

• Working on the Compatibility Tracking System for CondDB.

Marco Ca.

• Released the new stack up to Rec.

Alex

• Waiting for the nightlies to work to check the new Rivet tests.
