Philippe about the Architects Forum
  • LCG 47 with ROOT 5.13, new SEAL (bugfix), Qt4 and pyQt4 available soon
  • Fixes for gcc323 requested (still missing)
  • SLC4 uses gcc 3.4.6 instead of 3.4.5, the platform tag will be renamed to slc4_ia32_gcc34
  • Castor2 client library will not be released for Windows
  • rfio protocol exists in 2 flavors: a new ccommon version of libshift will be released, which will support both protocols through plugins
  • Application Area internal review after LHCb week. Reviewers for LHCb: Marco Cl. ( who replaces Marco Ca.) and Gerard
Marco Cl.: we need a map of protocols, URLs and libraries. Philippe volunteers to prepare a map while waiting from an official one.

Software Releases

Gaudi (Hubert)

  • v18r7 released * all changes mentioned last week * fix in ToolSvc * G.O.D. removed (included in LHCb)
  • Monitoring service implementation by Ben King doesn't compile on win32
  • Problem with ROOT GFAL plugin: globus rls dir contained both optimized and debug versions, the plugin was linked against dbg version, which was then deleted

LHCb, Boole, Brunel (Marco Ca.)

Built everything
  • Boole
    • Couple of bugfixes (RICH summary)
    • Serious bug in L0 Calo, it needs to be rerun in DaVinci if needed
  • Velo test beam code depends on Boole, the needed package will be moved to LbCom to avoit the dependency

Gauss (Gloria)

  • Latest version of Gauss released of Friday. No failure messages arrived from the production yet
  • Building Gauss on SLC4. It needs fixes and the build of GENSER

DaVinci (Juan)

  • New release:
    • Olivier D. provided the code for ?0 particle making
    • Loki changed to support new particles
    • internal changes in CALO particles
  • Implemented tests using cppunits in a generic way.
Marco Cl. asked if they can have a chat about it because he wanted something similar.

Round Table

Andres and Greig
They managed to modify the StagerSvc to use gfal, but they have technical problems to implement the pre-staging.
Tried to reduce the number of files of GaudiPI. 6 files are needed for histograms, but the analysis factory bringsin all the rest.
We agreed that we want only histograms.
Almost ready with new CMT. Working on install area for include files.
Marco Ca.
Re-deploying DataOnDemand using map properties.
Velo needs a backward incompatible change in XmlDDDB. It should be handled with CondDB versioning. Marco Cl. said that in a few of weeks we can deploy an SQLite file instead of XML (few details to be sorted out).
Job option directive #print doesn't work anymore. It should be added to the new JobOptionSvc.
Marco Cl.
Few changes in DetCond. Mainly a bugfix and a second thread that disconnects from the DB after a long idle period (off by default).
