Version

v12r5
Release Date 2 December 2004
Description

 

Backward-compatible development version. Based on Gaudi v15r5 and LHCb v16r4. Includes LoKi v3r6.

 

New version with some modifications and many additions. All changes that could interfere with the stripping but were not needed appear in this version.

Also there are many new features to allow the development of the HLT.

 
Main modifications

Physics:

  • loadTools() has been made private in DVAlgorithm. Remove all instances in your private code.

  • New KFFitTool doing vertex fits allowing usage of photons, constraints on intermediate resonances...

  • Bug fix in the ParabolicTransporter.

  • Updated DaVinciEff package. See the documentation note.

  • The DebugTool now uses standard units (configurable by options).

  • LoKi v3r6

Trigger:

  • New Hlt/HltGeneric, the L1-confirmation algorithm for the HLT

  • Bug fix in Trg sequence

  • New RichHltSys with several other packages allowing to use RICH in the HLT.

  • The TrgParticleMaker now can use Calo and RICH.

  • LoKiHlt v2r0
New platform

(copied from Marco's mail to lhcb)

 A new version of linux, scientific linux CERN 3 (slc3), has been deployed at CERN. All DaVinci versions starting from v12r3 are compiled for this platform too.

We strongly recommend to lxplus users to move to SLC3 at your earliest convenience. You can login to the CERN SLC3 cluster using the alias lxslc3 (i.e. ssh lxslc3 instead of ssh lxplus). Note that currently the slc3 machines are rather empty, so you should gain by making the move early.

The lxplus alias will be changed to point to the lxslc3 cluster early in January. Redhat7.3 will continue to be accessible via the lxplus7 alias for some time after that, but the capacity will be reduced rather rapidly.

The LHCb software will from now on be released for slc3 in both optimised and debug builds. We will continue to provide optimised binaries for rh73 for as long as there is demand.

Please report any problem.
Known problems: Troubles with RFIO: Crashes in PoolRootTreeEvtCnvSvc. Try to use the following trick, which seems to work fine:
  • Copy the file
    /afs/cern.ch/user/p/pkoppenb/public/.rootauthrc
    to your home directory
  • Make sure there is no .rootrc file there, or at least that you know what it is doing.
  • Replace all the "rfio:" by "castor:" in your input data. It will look like
    EventSelector.Input   = {
    "DATAFILE='PFN:castor:/castor/cern.ch/lhcb/DC04/00000541_00000665_9.dst'
    TYP='POOL_ROOTTREE' OPT='READ'"};
    This will pick up rootd instead of rfio.
