FPMC interface for Athena

How to compile FPMC and interface

• Fpmc currnetly works only with relaese 14.2.20 (in rel. 14.2.10., 14.2.22 etc. are some compilation problems, will be solved in near future)
• Log to Lxplus
• Go to working directory
• Create directory testarea/14.2.20 (mkdir -p testarea/14.2.20)
• cd testarea/14.2.20
• Copy source files for Fpmc: cp -r /afs/cern.ch/atlas/project/rp220/juranek/public/FpmcToAthena/External .
• Copy source files for Fpmc interface: cp -r /afs/cern.ch/atlas/project/rp220/juranek/public/FpmcToAthena/Generators .
• Copy configuration files for developer setting: cp -r /afs/cern.ch/atlas/project/rp220/juranek/public/FpmcToAthena/cmthome2 .
• Edit requierments file: change line macro ATLAS_TEST_AREA ${HOME}/rp220/testarea14 to point to right working directory, e.g. macro ATLAS_TEST_AREA ${HOME}/testarea
• Run initila setup: source /afs/cern.ch/sw/contrib/CMT/v1r20p20080222/mgr/setup.sh
• Create setup scripts: cd cmthome2; cmt config; cd ..
• Setup enviroment: source cmthome2/setup.sh -tag=14.2.20,32
• Compile Fpmc:

      cd External/Fpmc/cmt
      cmt config
      source setup.sh
      gmake
      

• Compile Fpmc interface:

      cd ../../../Generators/Fpmc_i/cmt
      cmt config
      source setup.sh
      gmake
      

• Now cmthome2 can be removed: cd ../../..; rm -rf cmthome2
• Create directory for user setup and copy requirement file: mkdir cmthome; cd cmthome; cp /afs/cern.ch/atlas/project/rp220/juranek/public/FpmcToAthena/cmthome/requirements .
• Edit requierments file: change line macro ATLAS_TEST_AREA ${HOME}/rp220/testarea14 to point to right working directory, e.g. macro ATLAS_TEST_AREA ${HOME}/testarea
• Create setup scripts: cmt config
• Set up user enviroment: source setup.sh -tag=14.2.20
• Check out Physics analysis package: cd ..; cmt co PhysicsAnalysis/AnalysisCommon/UserAnalysis
• Done, now for common usage see section bellow

How to run FPMC

• Log to Lxplus
• Go to testarea/14.2.20
• Set up user enviroment: source cmthome/setup.sh -tag=14.2.20
• Go to Physic analysis package into run directory: cd PhysicsAnalysis/AnalysisCommon/UserAnalysis/run
• Create python job options scritp e.g. jobOptions.fpmc.py, which should looks like:

  ###############################################################
  #
  # Job options file
  #
  #==============================================================
  #--------------------------------------------------------------
  # Private Application Configuration option
  from AthenaCommon.AppMgr import ServiceMgr
  ServiceMgr.MessageSvc.OutputLevel = INFO
  
  #--------------------------------------------------------------
  # Event related parameters
  #--------------------------------------------------------------
  # Number of events to be processed (default is 10)
  theApp.EvtMax = 100

  #--------------------------------------------------------------
  from AthenaServices.AthenaServicesConf import AtRndmGenSvc
  ServiceMgr += AtRndmGenSvc()
  ServiceMgr.AtRndmGenSvc.Seeds = ["FPMC 390020611 821000366", "FPMC_INIT 820021 2347532"]
  
  from AthenaCommon.AlgSequence import AlgSequence
  job=AlgSequence()
  from Fpmc_i.Fpmc_iConf import Fpmc
  job +=Fpmc()
  job.Fpmc.FpmcCommand = ["typepr EXC","typint QCD","iproc 19999","gapspr 0.03","prospr 0.9","cdffac 3.8","nflux 11","ifitpdf 10","rmass 201 120","yjmax 10","isoftm 1","q2wwmn 0.0","q2wwmx  4.0","ywwmax 0.1"]
  
  #from TruthExamples.TruthExamplesConf import DumpMC
  #job += DumpMC()
  
  from AthenaPoolCnvSvc.WriteAthenaPool import AthenaPoolOutputStream
  Stream1 = AthenaPoolOutputStream( "Stream1")
  Stream1.OutputFile = "fpmcOnly.pool.root"
  Stream1.ItemList += [ 'EventInfo#*', 'McEventCollection#*' ]
  
  
  #==============================================================
  #
  # End of job options file
  #

• Run job options file: athena jobOptions.fpmc.py
