Setup local environment

The setup of the local environment has the same logic than in previous CRAB versions. It is needed to setup the environment in the proper order, as listed here below:

If necessary, source the LCG User Interface environment; on lxplus5.cern.ch users have it on AFS:
```
source /afs/cern.ch/cms/LCG/LCG-2/UI/cms_ui_env.csh
```
For lxplus.cern.ch or most SL6 hosts, this step is not necessary.

Setup the relevant CMSSW environment:

mkdir MyTasks
cd MyTasks
cmsrel CMSSW_X_X_X
cd CMSSW_X_X_X/src/
cmsenv

Source the CRAB3 script file /cvmfs/cms.cern.ch/crab3/crab_pre.sh:
```
source /cvmfs/cms.cern.ch/crab3/crab_pre.sh
```

Data Analysis

CRAB3 Config File

Next, copy/paste from below (changing the text in red) into a file named crabConfig.py.

from WMCore.Configuration import Configuration
import os

config = Configuration()

## General options for the client
config.section_("General")
config.General.requestName   = 'test1'
#config.General.instance = 'preprod'

## Specific option of the job type
## these options are directly readable from the job type plugin
config.section_("JobType")
config.JobType.pluginName  = 'Analysis'
config.JobType.psetName    = 'pset.py'

## Specific data options
config.section_("Data")
config.Data.inputDataset = '/GenericTTbar/HC-CMSSW_5_3_1_START53_V5-v1/GEN-SIM-RECO'
config.Data.splitting = 'LumiBased'
config.Data.unitsPerJob = 100

## User options
config.section_("User")
config.User.email = ''

config.section_("Site")
config.Site.storageSite = 'T2_US_Nowhere'

Setup your CMSSW config file

In the above section, we set CRAB3 to look for a PSet named pset.py. If you do not already have an analysis you are running, copy/paste the below text into pset.py.

Show pset... Close

import FWCore.ParameterSet.Config as cms
process = cms.Process('NoSplit')
process.source = cms.Source('PoolSource',
  fileNames = cms.untracked.vstring("/store/mc/HC/GenericTTbar/GEN-SIM-RECO/CMSSW_5_3_1_START53_V5-v1/0010/FC85224E-EAAD-E111-AB01-0025901D629C.root"),
  skipEvents = cms.untracked.uint32(0),
)

process.dump = cms.EDAnalyzer("EventContentAnalyzer", listContent=cms.untracked.bool(False), getData=cms.untracked.bool(True))
process.load("FWCore.MessageService.MessageLogger_cfi")
process.MessageLogger.cerr.FwkReport.reportEvery = 10

process.maxEvents = cms.untracked.PSet(
    input = cms.untracked.int32(50)
)

process.Timing = cms.Service("Timing",
    useJobReport = cms.untracked.bool(True),
    summaryOnly = cms.untracked.bool(True),
)

process.o = cms.OutputModule("PoolOutputModule", fileName = cms.untracked.string("dumper.root"), outputCommands=cms.untracked.vstring("drop *"))

process.out = cms.EndPath(process.o)

process.p = cms.Path(process.dump)

Private MC

CRAB configuration file

To run private MC, copy/paste from below (changing the text in red) into a file named crabConfig.py.

from WMCore.Configuration import Configuration
import os

config = Configuration()

## General options for the client
config.section_("General")
config.General.requestName   = 'test1'
#config.General.instance = 'preprod'

## Specific option of the job type
## these options are directly readable from the job type plugin
config.section_("JobType")
config.JobType.pluginName  = 'PrivateMC'
config.JobType.psetName    = 'pset.py'

## Specific data options
config.section_("Data")
config.Data.inputDataset = '/GenericTTbar/HC-CMSSW_5_3_1_START53_V5-v1/GEN-SIM-RECO'
config.Data.splitting = 'EventBased'
config.Data.unitsPerJob = 10
config.Data.totalUnits = 200

## User options
config.section_("User")
config.User.email = ''

config.section_("Site")
config.Site.storageSite = 'T2_US_Nowhere'

Setup your CMSSW config file

In the above section, we set CRAB3 to look for a PSet named pset.py. If you do not already have a MC configuration, copy/paste the below text into pset.py, works with CMSW_5_3_4.

Run CRAB3

You're ready to run CRAB3! A few commands:

Submit the jobs:
```
crab submit
```
Check the status of all the jobs:
```
crab status -t crab_test1
```
Retrieve the output of the jobs:
```
crab getoutput -t crab_test1 -q all
```
See the list of good lumis for your task:
```
crab report -t crab_test1
```

cmsrel CMSSW_X_X_X

cd CMSSW_X_X_X/src

Start by configuring the environment for CMS, the grid UI, and CRAB3. At CERN, the commands are: cmsenv source /afs/cern.ch/cms/LCG/LCG-2/UI/cms_ui_env.sh source /cvmfs/cms.cern.ch/crab3/crab.sh
