Minutes : Florence Ranjard

      1. Code Check tools evaluation: method and plan (S.Paoli/IT-IPT)

LHCb would like to use a Code Check tool. Several are avalaible on the market. How to choose.
Stefano has presented the method and plan IPT will follow to evaluate the various products

http://home.cern.ch/paoli/CCUevaluation/index.htm

the Evaluation Criteria are avalaible in http://home.cern.ch/paoli/EvaluationCriteria.pdf

For LHCb it is essential that the tool runs on NT and Linux and does not require any support from LHCb.

The LHCb librarian could first test the could on Gaudi . Then the selected tools would be pass on to the Gaudi team.

      2. Lxplus and shiftlhcb status report (C.Rafflin, T.Cass)

lxp01, lxp02 are running rehat5.1, lxp03 is running redhat6 but with the same compiler as on redhat5.1

redhat6 runs with a MIT version of afs, IT is waiting for a transarc version of afs, The final move to redhat6 will take place
when afs/transarc will work properly under redhat6.

lxplus was found rather slow by users. IT is waiting for 15 more PCs faster and with more memory late October.
At the same time monitor tools were missing to analyze the traffic on lxplus.

shiftlhcb has not arrived end of July as forseen but it is now avalaible.

Many physicists have a Linux PC on their desk. They could install the same settings on their PC than on lxplus and submit
batch jobs to shiftlhcb from there

It will be interesting to get STAROFFICE installed on the desktop PCs.

       3. LHCb NT server (T.Cass)

Tony will check with F.Hemmer the status of the LHCb NT server project.

        4. SICB status report (A.Jacholkowska)

The new SICB v219 is now released on 4 platforms (NT, AIX, HP-UX, Linux)

• It uses Pythia6125 and QQ and the detector optimization from SICB v119.
  • look at LHCb notes 27 and 28 for details on the Pythia/QQ implementation.
• The database to be used is stored in $LHCBSOFT/dbase/v219.
• It reads the field map field03a.cdf in ascii format on all platforms.
• Agnieszka will test it before going to production.
• before the 1 October it is forseen to:
  • tune the reconstruction,
  • update axselib
  • produce test data on NT : 10K of mbias, bbar, B0d->muX, B0d->eX
• after the 1 October:
  • produce large test data samples on NT : 100K.
• pending problems:
  • magnetic field map
  • beam pipe
  • size of the output data

     ===> when SICB v219 will be released, developpers should work with CMT.
