This repository proves scripts to run private MC generation. It consists of the exact same cmsDriver.py commands used in central production (...painstaking copied by hand from MCM).
Setup instructions (note: git cms-addpkg has to work):
git clone [email protected]:DryRun/MYOMC.git
cd MYOMC
source firsttime.sh
# For future sessions, run env.sh
Run a test job:
cd $MYOMC/test
source runtest.sh local
# Or
# source runtest.sh condor
See the test script for the syntax.
NANOGEN (twiki) is a lightweight data format containing only generator-level information. The input is a pythia fragment, e.g. one downloaded from MCM or the GEN repositories. Assuming you have a fragment named fragment.py, the usage is as follows:
cd MYOMC
# source firsttime.sh # If you haven't run this before, execute this to pre-create some CMSSW environment tarballs
source env.sh
python localtest.py jobname path/to/fragment.py NANOGEN --nevents 10000
# To run on condor instead of local:
# python crun.py jobname path/to/fragment.py NANOGEN -e --nevents_job 5000 --njobs 10 --keepNANOGEN # See crun.py for more condor options like output saving, memory requirements, etc.
Here's an example pythia fragment, which uses a Madgraph gridpack:
fragment.py
import FWCore.ParameterSet.Config as cms
externalLHEProducer = cms.EDProducer("ExternalLHEProducer",
args = cms.vstring('/eos/.../username/gridpacks/my_gridpack_slc7_amd64_gcc900_CMSSW_12_0_2_tarball.tar.xz'),
nEvents = cms.untracked.uint32(5000),
numberOfParameters = cms.uint32(1),
outputFile = cms.string('cmsgrid_final.lhe'),
generateConcurrently = cms.untracked.bool(True),
scriptName = cms.FileInPath('GeneratorInterface/LHEInterface/data/run_generic_tarball_cvmfs.sh')
#scriptName = cms.FileInPath('GeneratorInterface/LHEInterface/data/run_generic_tarball_xrootd.sh')
