• LBCORE-14: collected the list of externals used, investigating removals

Round Table

Gloria

• High frequency of stalled jobs with the new physics list: 2% (normal) -> 10% (new physics list)
  • cannot be fixed before production, so we may have to cope with it while looking for a fix
• New configuration of the generators location in LCG (using LCG version in the name). We want it in production, but Ben has to fix the scripts.
• Waiting for a JIRA project (LBCORE-62)

Joel

• lxbuild119 up and running (SLC6)
  • half for the services and half for builds
• New LHCbDirac in production since Monday (problem with restart of agents)

Illya

• Ariadne
  • defined how to handle security: use Apache virtual host
  • ready to install on the new machine (lxbuild119)
  • backup policy still to be defined, but not needed for testing
  • will discuss with Joel details

Liang

• Changes in DetCond to allow multiple compression mechanism
• Will commit a script to compress the database (to decide where)

Rob

• Code review
  • usage of tools: probably used too much (used as wrappers around simple functions)
    • generally approved
  • reorganize memory layout of classes
    • requires more discussion
  • use Gaudi configurables more: move conditional and derived configuration to Python
