View source for SCRIPT FOR RUNNING ON REMOTE DATASETS

'''To do only once :'''

* Assumes that you have compiled and tested your Athena code locally.
* Then, copy your package on lxplus (on the scratch to avoid quota issues. see https://twiki.cern.ch/twiki/bin/view/Atlas/GangaTutorial5, https://twiki.cern.ch/twiki/bin/view/Atlas/GangaShortTutorial5 and http://www-hep2.fzu.cz/twiki/bin/view/ATLAS/AthenaRelated to see how to setup Athena and Ganga on lxplus)

* Create a Load.Athena function in your profile script (below, what I put in .zshrc ) :

    function Load.Athena {
      echo "Example : Load.Athena 15.3.1,setup,32"
      source ${HOME}/cmthome/setup.sh -tag=$*
      shift
    }

* Create a Load.Ganga function in your profile script (below, what I put in .zshrc ) :
    function Load.Ganga {
       echo "Loading Ganga Environment"
       echo "Your LFC host:" ${LFC_HOST}
       # automatic LXPLUS Ganga setup
       source /afs/cern.ch/sw/ganga/install/etc/setup-atlas.sh $*
    }

'''To do each time you want to use ganga :'''
* From your home directory : Load.Athena 15.3.1,setup,32
   cd $TestArea/<path/to/analysis/package>/cmt
   source setup.sh
   cd ../run
   Load.Ganga


and edit a ganga joboption as follows :

   j = Job()
   j.name='LCG_SU3' # the name you want 
   j.application=Athena()
   j.application.atlas_release = '15.3.1.6' # or anything else release
   j.application.exclude_from_user_area=["*.o","*.root*","*.exe"]
   j.application.prepare_old(athena_compile=True) # if need to use your own unofficial package
   j.application.option_file = 'Analysis_common_gangaTopOption.py' # joboption defining the common definition, useful when want to run the same code on many datasets
   j.application.max_events=-1
   j.inputdata = DQ2Dataset()
   j.inputdata.dataset="mc08.105403.SU3_jimmy_susy.merge.AOD.e352_s462_r635_t53/" # your dataset
   j.outputdata=DQ2OutputDataset()
   j.outputdata.datasetname='105403.SU3._t53_v2' # the name of your production
   j.outputdata.outputdata=['Analysis.aan.root']
   j.backend=LCG() # run on LCG because all datasets not available on nordugrid
   j.backend.requirements=AtlasLCGRequirements()
   j.backend.requirements.cloud = 'FR' # or anything else :-)
   j.splitter=DQ2JobSplitter()
   j.splitter.numsubjobs=2
   j.submit()
