News

• From A.F.
  • ROOT 6 is a bit late (should be ready by the end of the year)
  • slc6-gcc47 stack being prepared (GCC 4.7.2 with C++11 standard)
  • Python 2.7 ... not so clear
• LCGCMT 64b to be prepared today (requested for the next Gaudi)
  • ROOT 5.34/03
  • FastJet 3.0.3
  • TBB 4.1
  • Qt?
• LHCbDirac moved to JIRA for bug/issue tracking (https://its.cern.ch/jira/browse/LHCBDIRAC)
• Marco Ca.: Pere announced "Manycores and Concurrency Workshop" in Fermilab, we should contribute (4-6 Feb 2013)

Issues from last meeting

• Use of ssh instead of http for SVN checkout in the nightlies

Round Table

Marco Cl.

• Gaudi release foreseen for beginning of next week (release notes in preparation)
  • fixes for return codes
  • usable CMake configuration, with the help of LbScripts (documentation in preparation)
• Reported ROOT bug #98693 (inconsistent behavior after segfault in Python)
  • the fix seems to be a change on our side (i.e. use ROOT instead of PyCintex)
• CMake configuration
  • several small fixes and improvements (cleaner installation, support for path cleaning and python.zip)
  • prepared a 'generic' Makefile for CMake projects, more or less equivalent to the CMT one
  • validation is at a good stage:
    • build from Gaudi to Brunel (in less than 30 min with '-j 20' and distcc), plus a 'cmtuser' project with one package
    • successful tests
    • same or equivalent build products
    • some differences in the environment (order of directories in the paths)
  • To Do:
    • improve 'tag_package' integration
    • support in SetupProject (both build and run time)
    • support for recursive getpack
    • integration with release management tools (who should do it?)
    • have a nightly build slot (use Jenkins?)
      We need updated in the nightlies to modify the CMake configuration on the fly, if needed.
  • Can I start to commit CMake configuration files to LHCb, Lbcom, Rec, Brunel?

Gloria

• Something strange in the nightlies: new version of EvtGen breaks the nighlties because of a missing header... which seems to be there
• We have a list of PDFs we want for production, but it will need to change in the future. Unfortunately the list is hardcoded in the packaging script: we need a better way to configure the list, possibly from Gauss.

Marco Ca.

• New release of the stack around LHCb week: new Gaudi plus some MC-related changes by Chris.

Ben

• FastJet 3.0.3 validated by Victor Coco
  • Gloria: also Gauss depends on it (Rivet)
• Waiting for SFT rpms to go on on rpm
• Discussion with Benedikt about status of the nightlies
  • they are going to use ElectricCommander
  • we could do something similar with Jenkins (prepared a test instance)
• Running a full chain of performance jobs

Illya

• Continuing on the CTS and finalizing the conference paper (deadline on Friday).

Liang

• Working on improving the deployment of the SQLite files.

Thomas

• Problem with the nightlies build logs: not copied to AFS. Not yet clear why.
• getpack using ssh instead of http
