AA nightly builds are proceding well, Pere and Hubert are working to get Gaudi in the system.
Software Releases
Gaudi (Hubert)
- 2 patches by Vania:
- changes to VectorMap (requested by Atlas)
- changes for vectors in N-Tuples (for Patrick)
- All the changes in v18 branch has been merged in v19 plus
- PluginSvc (Pere), to be removed as soon as it is in Reflex
- Usage of InstallArea
It would be nice to have a preview of v19 (dev version?) to test the new features (and InstallArea). Probably it is not possible because the PluginSvc rely on changes in ROOT HEAD.
Marco Ca.: The 2 packages LHCbDefinitions (typedefs) and LHCbMath could be moved to Gaudi.
After some discussion we agreed to have LHCbDefinitions moved to GaudiKernel and reorganize LHCbMath.
LHCb, Boole, Brunel (Marco Ca.)
- Final DC06 version released on Tuesday
- We should freeze LHCb.
- HLT code is in REC. Since the updates in HLT code are quite frequent, it's better to have a separate project.%BR$ Will start an HLT project and prepare a new release of REC (HLT-free).
Gauss (Gloria)
- Released a build without SSE2 option.
- Changes in EvtGen (new CP-violating decay channels)
- Probably not the latestd DC06 "compatible" (trying not to branch)
DaVinci (Juan)
- Working on speed-up of preselection (factor 10 gained already, but not enough)
- Release in few days
Panoramix (Philippe for Thomas)
- Guy working on a release on open scientist v16.
- proposed a first release (v13r10) on latest REC and PHYS
- v14r0 on OSC-16 (testing)
Round Table
- Marco Cl.
- Do we want to keep using hyper-news for llhcb-core-soft?
The only good point of H.N. seems to be the search facility, but the mail gateway is unusable. After some discussion, it seems that the best solution is to go back to SIMBA for the mailing list, and use H.N. only as an archiver.
- Hubert
- New web pages:
- Added custom title
- Effort to make the scripts more flexible not to copy the files locally
- Panoramix? -> Florence with the help of Gloria Marco Ca. will prepare the page for Moore.
- Matt
- Which type to use for a 64 bit integer?
"long long" is a 64 bit integer on ia32, amd64 and win32, probably not really standard, but working for the moment. Marco Cl. suggest to consider the possibility of a set platform independent typedefs (either self-defined or from a 3rd party, like ROOT).
- Philippe
- Struggling with old workflows. Getting ready to start stripping in January.
- Philippe for Thomas
-
- Python users are waiting for fixes in ROOT.
- Problem of twin files in DC06 v2 undestood (run number with only 13bits).
