Production at the CC / IN2P3

  • A first look at the receipe specific to each release: release recipes

  • Installation of UserAnalysis against 11.0.3
  • Initial setup :
    > mkdir 11.0.3 and cd 11.0.3/
    > edit SOURCEME.sh and set the release number
    > source SOURCEME.sh
    > klog.krb "login" -cell cern.ch
    > tokens.krb

  • Check Out and compilation of UserAnalysis:
    > cmt co -r UserAnalysis-xx-xx-xx PhysicsAnalysis/AnalysisCommon/UserAnalysis
    > cd /PhysicsAnalysis/AnalysisCommon/UserAnalysis/UserAnalysis-xx-xx-xx/cmt/
    > cmt config
    > source setup.sh
    > cmt bro gmake
    > cd ../run
    > get_files PDGTABLE.MeV
    •

  • Running an Event Generator
  • Using TopRex:
    > get_files -jo jobOptions.toprex.py
    > edit jobOptions.toprex.py and set paramters (generator & file names)
    > edit toprex_process.dat file
    > ln -s toprex_process.dat toprex.dat
    > (time) athena.py jobOptions.toprex.py
  • Using AcerMC:
    > first, produce the events with the standalone package, options ACER 2 in run.card
    > cp standalone/AcerMC_p019_r945169.events into /run
    > cp standalone/AcerMC_p019_r945169.inparm into /run
    > ln -s AcerMC_p019_r945169.inpar inparmAcerMC.dat
    > get_files -jo jobOptions.AcerMCPythia.py for PYTHIA hadronization
    > get_files -jo jobOptions.AcerMCHerwig.py for HERWIG hadronization
    > and to get generated event POOL file, add the lines: 
                #---------------------------------------------------------------
            # POOL / Root output
            #---------------------------------------------------------------
            include( "AthenaPoolCnvSvc/WriteAthenaPool_jobOptions.py" )
            theApp.Dlls   += [ "GeneratorObjectsAthenaPoolPoolCnv" ]
            Stream1.ItemList += ["2101#*", "133273#*" ]
            Stream1.OutputFile = "MYTEST." + identifier + "." + process + "." + filenumber + ".evgen.pool.root"
    > (time) athena.py jobOptions.AcerMCPythia.py

  • Making FastSim AOD from generated events:
    > get_file FastSimToAOD_jobOptions.py:
     
    # flags for AOD / ATLFAST :
    from ParticleEventAthenaPool.AODFlags import AODFlags
    AODFlags.allSetOff()
    AODFlags.fastSetOn()
    AODFlags.FastSimulation = True
    AODFlags.SpclMC = True
    AODFlags.MissingEtTruth = False

  • Making digitized evts from simulated events:
  • Making reconstructed evts from digitized events:
  • Making AOD's:
