Where to find the MC files

The status of MC files can be found here . Go to DBS , click on Navigator, copy the string corresponding to the MC files.

How to run on Grid (UNDER CONSTRUCTION)

The first time:

• To get a Grid certificate follow the instructions in Starting with the Grid from the WorkBook .
  In particular look at How to getaccess to WLCG. It takes few days to have a certificate. You should have it then already imported in your browser. If you do not have it, you can import it, i.e. in Firefox from Preferences -> Advanced -> Encryption -> View certificates -> Your certificates -> Import.
• After you have done all registration, to check that you are in the CMS virtual organization go to the CMS VOMRS server -> choose my certificate -> Check the Autorization Status like Rights and Expiration date.
• Now you can use the certificate. Login to lxplus, copy your certificate in an area. Then follow the instructions listed here . Before starting with the Proxy:
  source /afs/cern.ch/cms/LCG/LCG-2/UI/cms_ui_env.csh
  The proxy is valid 12 hours.
• Just to try, you can follow the steps in the Crab Tutorial , otherwise look below.

For all other times:

• source /afs/cern.ch/cms/LCG/LCG-2/UI/cms_ui_env.csh
  voms-proxy-init -voms cms (and Enter the Grid phrase that you have chosen)
  source /afs/cern.ch/cms/ccs/wm/scripts/Crab/crab.csh 
  

• resetup the area

  cd myarea/CMSSW_x_x_x/src, like  ~/scratch0/StarterKit/CMSSW_2_1_9/src (for the AOD to PAT)
                             or like ~/scratch0/CMSSW_2_2_4/src/Firenze/Reduction/test (for the PAT to Firenze's ntuples)
  eval `scramv1 r -csh`
  

• copy the crab.cfg from $CRABDIR/python/crab.cfg if you do not have it already
• modify it to include:
  - the input file from DBS. For instance look for Zmumu, find the path /Zmumu/Summer08_IDEAL_V9_v1/GEN-SIM-RECO, and put that string after datasetpath=, like datasetpath=/Zmumu/Summer08_IDEAL_V9_v1/GEN-SIM-RECO
  - the cfg file in pset, like pset=patLayer1_fromAOD_full.cfg.py
  - the total numbers of events and total number of jobs, at least 2 out of the 3 have to be filled.
  - the name of the output file specified in cfg.py. If small it can be just the file. In this case specify return_data=1 and copy_data=0.
• For bigger output files:
  - split the jobs like

  total_number_of_events=10000
  events_per_job = 1000
  

  - create a directory in castor for the output file
  

  rfmkdir /castor/cern.ch/user/e/egallo/Zmumu
  rfchmod +775 /castor/cern.ch/user/e/egallo/Zmumu
  

  - in the crab.cfg file specify

  ### OUTPUT files Management
  ##  output back into UI
  return_data = 0
  
  ### OUTPUT files INTO A SE
  copy_data = 1
  storage_element = srm-cms.cern.ch
  storage_path=/srm/managerv2?SFN=/castor/cern.ch
  lfn=/user/e/egallo/Zmumu
  
  
  (storage_path = /srm/managerv2?SFN=/castor/cern.ch/user/e/egallo/Zmumu IS THE OLD WAY)
  

• execute crab commands

  crab -h
  if it is gives error: eval `scramv1 r -csh`
  crab -create  (crea un certo numero di directories)
  crab -submit
  crab -status
  

• Look at the status of your job here after selecting you as a user.
• when the job is done, get the output with

   crab -getoutput 

  The output file is copied in the subdirectory crab_xxx/res.

  To kill

  crab -kill all -c crab_0_101125_010648(for instance)

crab -copyData [range -dest_se=the official SE name or -dest_endpoint=the
complete endpoint of the remote SE]

       Option that can be used only if your output have been previously
copied by CRAB on a remote SE.  By default the copyData copies your output
       from the remote SE locally on the current CRAB working directory
(under res). Otherwise you can copy the output from the remote SE to
       another one, specifying either -dest_se=
or -dest_endpoint=. If dest_se is
       used, CRAB finds the correct path where the output can be stored.

       Example: crab -copyData  --> output copied to crab_working_dir/res
directory
                crab -copyData -dest_se=T2_IT_Legnaro -->  output copied to
the legnaro SE, directory discovered by CRAB
                crab -copyData
-dest_endpoint=srm://:8443/xxx/yyyy/zzzz --> output copied to the
se  under
                /xxx/yyyy/zzzz directory.
