Ambiente cms

Creazione ambiente cms

  • scram project -n [cartella] CMSSW CMSSW_#versione
mettere al posto di [cartella] il percorso della cartella in cui installare CMSSW; sostituire al posto di #versione il numero della versione desiderata nella forma x_y_z.

p.e.:

scram project -n CMSSW536 CMSSW CMSSW_5_3_6

Inizializzazione cms

Entrare nella cartella src/ dell'ambiente CMSSW e dare il comando

  • cmsenv
p.e.:

cd CMSSW536/src

cmsenv

Creazione MC

Il procedimento è composto di 2 parti:

1. Conversione campione lhe in ntpla root

Bisogna creare una ntpla root dal campione lhe eseguendo il seguente script di python.

Formato script python

creare "script lhe-root".py: 

# Auto generated configuration file
# using: 
# Revision: 1.353 
# Source: /local/reps/CMSSW.admin/CMSSW/Configuration/PyReleaseValidation/python/ConfigBuilder.py,v

import FWCore.ParameterSet.Config as cms
process = cms.Process('LHE')

process.load('Configuration.StandardSequences.MagneticField_38T_cff')
process.load('Configuration.StandardSequences.FrontierConditions_GlobalTag_cff')
process.maxEvents = cms.untracked.PSet(

inserire nella seguente riga il numero di eventi da elaborare al posto di #eventi 

    input = cms.untracked.int32(#eventi)
)

# Input source
process.source = cms.Source("LHESource",

sostituire a [file input] il percorso del file lhe di cui convertire gli eventi 

fileNames = cms.untracked.vstring('file:[file input].lhe')
)
process.options = cms.untracked.PSet(
wantSummary = cms.untracked.bool(True)
)

# Production Info
process.configurationMetadata = cms.untracked.PSet(
    version = cms.untracked.string('$Revision: 1.2 $'),
    annotation = cms.untracked.string('MCDBtoEDM nevts:1'),
    name = cms.untracked.string('PyReleaseValidation')
)

# Output definition
process.RECOSIMoutput = cms.OutputModule("PoolOutputModule",
    splitLevel = cms.untracked.int32(0),
    eventAutoFlushCompressedSize = cms.untracked.int32(5242880),
    outputCommands = process.RECOSIMEventContent.outputCommands,

sostituire al posto di [file output] il nome della ntpla da ottenere 

    fileName = cms.untracked.string([file output].root'),
    dataset = cms.untracked.PSet(
        filterName = cms.untracked.string(''),
        dataTier = cms.untracked.string('GEN')
    )
)

# Additional output definition

# Other statements
process.GlobalTag.globaltag = 'START53_V7A::All'

# Path and EndPath definitions
process.RECOSIMoutput_step = cms.EndPath(process.RECOSIMoutput)

# Schedule definition
process.schedule = cms.Schedule(process.RECOSIMoutput_step)

dove "script lhe-root" e il nome dello script di python.

Lanciare lo script per la conversione

eseguire il comando

  • cmsRun "file lhe-root".py
(Ci vogliono circa 1 minuto di preparazione e 1 secondo ogni 1000 eventi per terminare l'operazione).

2. Generazione MC da ntpla root

Si genera infine il MC eseguendo il seguente script di python.

Formato script python

creare "script MC".py:

dove "script MC" è il nome dello script python.

 Lanciare lo script per la generazione del MC 



eseguire il comando

 
    

  •  cmsRun "script MC".py

 
(Ci vogliono circa 3 minuti di preparazione e 3 minuti ad evento).



 Sistema crab 



Con il sistema crab si può generare il MC dividendo gli eventi da elaborare tra jobs eseguiti da più macchine.

 Creazione del sistema crab 



Per poter utilizzare crab è necessario disporre delle autorizzazioni necessarie per l'accesso a tutti i file remoti richiesti dal sistema.

 Richiesta del certificato CA per GRID 



Aprire le impostazioni del proprio CERN Account Management, e richiedere il certificato CA per GRID cliccando su Request a CERN Grid Certification Authority Certificate.
