Introduction

This does not teach the details of GRID nor is a CRAB tutorial. For CRAB tutorial you must refer to WorkBookCRAB2Tutorial. A complete guide to CRAB is at SWGuideCrab. This exercise runs CRAB job to create a PATtuple from (skimmed) data and is part of the PAT tutorial exercises. The purpose of these exercises is to show PAT users how they can use Grid tools in creating their PAT tuple for CMS analysis. Having your storage space set up may take several days, Grid jobs run with some latency, and there can be problems. You should set aside about a week to complete these exercises. The actual effort required is not the whole week but a few hours. For CRAB questions unrelated to this twiki, please use the links CRAB2 FAQ and CRAB3.

Pre-requisite for this exercises

To perform this set of exercises you need a Grid Certificate, CMS VO membership and SiteDB registration. It is also assumed that you have CERN account. You must have a space to write out your output files to , say castor. All lxplus users have account on castor where they can write their CRAB jobs output.

Obtain a CERN account

  • Use the following link for a CMS CERN account: CMS CERN account
    • A CERN account is needed, for example, to login in to any e-learning web-site, or obtain a file from the afs area. A CERN account will be needed for future exercises.
    • Obtaining a CERN account can be time-consuming. To expedite the process please ask the relevant institutional team leader to perform the necessary "signing" after the online form has been submitted and received for initial processing by the secretariat.

Obtain a Grid Certificate, CMS VO membership and SiteDB registration

  • A Grid Certificate, CMS VO membership and SiteDB registration will be needed for the next set of exercises. The registration process can be time-consuming (actions by several people are required), so it is important to start it as soon as possible. There are three main requirements which can be simply summarized: A certificate ensures that you are who you claim to be. A registration in the VO recognizes your (identified by your certificate) as a member of CMS. A SiteDB is a database and web interface that CMS uses to track sites and also used by CRAB publication step to find out the hypernews username of a person from their Grid Certificate's DN (Distinguished Name) etc.. Please look at Get Your Grid Certificate, CMSVO and SiteDB registration to complete these three steps. All three steps are needed to be completed before you successfully submit jobs on the Grid.

Step 1 - Setup a release, setup CRAB environment and verify your grid certificate is OK

To setup a CMSSW release for our purpose, we will execute the following instructions:

Login to lxplus.cern.ch ad go to your working area ( preferably scratch0 area, for example /afs/cern.ch/user/m/malik/scratch0/). Then execute the following commands. We will call /afs/cern.ch/user/m/malik/scratch0/ as YOURWORKINGAREA.

Create a directory for this exercise (to avoid interference with code from the other exercises).

mkdir exercise04
cd exercise04

Create a local release area and enter it.

setenv SCRAM_ARCH slc5_amd64_gcc462
cmsrel CMSSW_7_4_1_patch4
cd CMSSW_7_4_1_patch4/src 

Set up the environment.

source /afs/cern.ch/cms/LCG/LCG-2/UI/cms_ui_env.csh
cmsenv

More on setup local Environment and prepare user analysis code are given here.

To setup CRAB execute the following command. The explanation of this command is given here.

source /afs/cern.ch/cms/ccs/wm/scripts/Crab/crab.csh

To verify that your certificate - It is assumed that you have successfully installed and followed the above instructions for setup. Now you verify that your GRID certificate has all the information needed.

Initialize your proxy

voms-proxy-init -voms cms
You should the following output:

Enter GRID pass phrase:
Your identity: /DC=org/DC=doegrids/OU=People/CN=Sudhir Malik 503653
Creating temporary proxy .......................... Done
Contacting  lcg-voms.cern.ch:15002 [/DC=ch/DC=cern/OU=computers/CN=lcg-voms.cern.ch] "cms" Done
Creating proxy ................... Done
Your proxy is valid until Fri Jul  1 22:41:34 2011

Now run the following command

voms-proxy-info -all | grep -Ei "role|subject"

The output should look like this:

subject   : /DC=org/DC=doegrids/OU=People/CN=Sudhir Malik 503653/CN=proxy
subject   : /DC=org/DC=doegrids/OU=People/CN=Sudhir Malik 503653
attribute : /cms/Role=NULL/Capability=NULL
attribute : /cms/uscms/Role=NULL/Capability=NULL

Step 2 - Know your data set name in the DBS

The data set name is needed to run the CRAB job.

In this exercise, we will use the data set used =/Jet/Run2011B-PromptReco-v1/AOD=.

I picked up this dataset from the twiki PhysicsPrimaryDatasets. Further, this dataset is also used in the script PhysicsTools/PatExamples/test/patTuple_data_cfg.py. This script is a standard script provided by PAT group to work with collision data and hence I picked it.

Before moving further, it would be interesting to see how to find this dataset in the DAS.

To do this open the DAS in a browser. In the ADVANCED KEYWORD SEARCH type the following :

dataset dataset=/Jet/Run2011B*

A page pops up ( after few seconds). There are several datasets listed on this page. The one we use is listed as /Jet/Run2011B-PromptReco-v1/AOD

You can also make use of the DBS Command Line Interpreter (CLI):

  • Having set your CMSSW environment invoke the dbs command:

cd exercise04/CMSSW_7_4_1_patch4/src
cmsenv
dbs search --query "find dataset where dataset=/Jet/Run2011B*"

The result below confirms what you already obtained with the DBS web interface:


Using DBS instance at: http://cmsdbsprod.cern.ch/cms_dbs_prod_global/servlet/DBSServlet
-------------------------------------------------------

/Jet/Run2011B-19Oct2011-HLTTest-v1/DQM
/Jet/Run2011B-15Nov2011-HiggsCert-v1/DQM

Step 3 - Run your PATtuple config file locally to make sure it works

First copy the python script patTuple_data_cfg.py to your local area. To do this, execute the following command:

cvs co -r CMSSW_7_4_1_patch4 PhysicsTools/PatExamples/test/patTuple_data_cfg.py

Before executing the python script patTuple_data_cfg.py, we need to edit this script and make three modifications. If you are daring, try to run the config file without and with modifications one by one and see the error messages you might get. These modifications are:

1. Change the line for global tag

process.GlobalTag.globaltag = 'GR_R_42_V12::All:'

to

process.GlobalTag.globaltag = 'GR_R_44_V11::All'

because we to use the appropriate gobal tag. More on global tag is SWGuideFrontierConditions.

2. Change

inputJetCorrLabel = ('AK5PF', ['L1Offset', 'L2Relative', 'L3Absolute', 'L2L3Residual'])

to

inputJetCorrLabel = ('AK5PF', [])#NO jet energy correction yet

because I chose not to use any jet correction.

3. Replace all the input data files with the following:

       '/store/data/Run2011A/Jet/AOD/PromptReco-v4/000/167/786/CA31E47B-1AA2-E011-B432-003048F1C58C.root',

because these correspond to our dataset chosen.

Now from your directory /YOURWORKINGAREA/exercise04/CMSSW_7_4_1_patch4/src, execute the following command

cmsRun PhysicsTools/PatExamples/test/patTuple_data_cfg.py

If successful, this will create an output file jet2011A_aod.root of size about 79MB with 1000 events.

Now you prepare the CRAB configuration file

Step 4 - Prepare your crab.py script for CRAB job submission

Your crab config files to submit CRAB job should look like this crab.cfg.

In this crab.cfg file, the name of the output file is jet2011A_aod.root. Make sure that this name of the output file is the same as defined in the line process.out.fileName = cms.untracked.string(''jet2011A_aod.root") in the file patTuple_data_cfg.py.

To look at what each of the line in crab.cfg means, refer to CRAB Tutorial.

This crab.cfg file contains storage_path as /srm/managerv2?SFN=/castor/cern.ch/user/m/malik/pattutorial/ that we create in the next step. In this exercise we run over the data set name /Jet/Run2011A-PromptReco-v4/AOD. This crab.cfg also uses a file called Cert_160404-167151_7TeV_PromptReco_Collisions11_JSON.txt. This file that describes which luminosity sections in which runs are considered good and should be processed. In CMS, this kind of file is in the JSON format. (JSON stands for Java Script Object Notation).

To find the most current good luminosity section files in JSON format, please visit https://cms-service-dqm.web.cern.ch/cms-service-dqm/CAF/certification/Collisions11/.

To know on how to work with files for Good Luminosity Sections in JSON format please look at the twiki SWGuideGoodLumiSectionsJSONFile.

Instructions on how to setup your crab jobs over selected lumi section is Running over selected luminosity blocks.

You can find the official (centrally produced) JSON format files here or on afs at the CAF area /afs/cern.ch/cms/CAF/CMSCOMM/COMM_DQM/certification. At the same locations as the JSON format file you can also find the txt file reporting the history of the quality and DCS selection and at the bottom the snippet to configure any CMSSW application for running on the selected good Lumi Sections.

Step 5 - Get JSON format file, creating writable directory in castor and setup CRAB environment

Get the JSON file to you WORKINGDIRECTORY/exercise04/CMSSW_7_4_1_patch4/src area

wget http://cms-service-dqm.web.cern.ch/cms-service-dqm/CAF/certification/Collisions11/7TeV/Prompt/Cert_160404-167151_7TeV_PromptReco_Collisions11_JSON.txt

Notice how character "s" was removed from "https". wget command does not like "https" somehow.

Create a directory in castor called pattutorial

rfmkdir /castor/cern.ch/user/m/malik/pattutorial
Create a directory in castor called jet2011A_AOD

rfmkdir /castor/cern.ch/user/m/malik/pattutorial/jet2011A_AOD
This directory has to be group writable, so change the persmission accordingly
rfchmod 775 /castor/cern.ch/user/m/malik/pattutorial/jet2011A_AOD

To see your created directory do:

nsls /castor/cern.ch/user/m/malik/pattutorial/jet2011A_AOD

Setup up CRAB environment

source /afs/cern.ch/cms/ccs/wm/scripts/Crab/crab.csh

Step 6 - Create CRAB job

To create your CRAB job, execute the following command:

crab -create

You should see the following output on the screen:

        CMS Dashboard: http://dashb-cms-job-task.cern.ch/taskmon.html#task=malik_crab_0_110702_181826_2c05hd
        Server page: http://vocms58.cern.ch:8888/logginfo
        Your task name is: malik_crab_0_110702_181826_2c05hd 

Log file is /afs/cern.ch/user/m/malik/scratch0/PAT2011JULY/CMSSW_4_2_4/src/crab_0_110702_181826/log/crab.log


You can also see the status of your CRAB job on the dashboard URL listed at end of the screen output of the above step i.e. http://dashb-cms-job-task.cern.ch/taskmon.html (here your task).

The contents of this URL will depend on the status of your jobs i.e. running, pending, successful, failed etc. An example scren shot of this URL is here:

crab_424_url.png

Another view of the url obtained by clicking on "TaskMonitorId" is:

crab_424_TaskId.png

NOTE: There could be a mismatch between seeing the status of your jobs by executing the command crab -status and the dashboard URL.

If you see any jobs with status successful, you should see the output root files in /castor in the directory /castor/cern.ch/user/m/malik/pattutorial/jet2011A_AOD

To look at this directory, do

rfdir /castor/cern.ch/user/m/malik/pattutorial/jet2011A_AOD

If there are any output files in this directory, it should look like this:

Step 9 - Job Output Retrieval Check for output files in /castor

For the jobs which are in the "Done" state it is possible to retrieve the log files of the jobs (just the log files), because the output files are copied to the Storage Element associated to the T2 specified on the crab.cfg which is /castor/cern.ch/user/m/malik/pattutorial/jet2011A_AOD in our case and infact return_data is 0 which means we are not publishing the data to the DBS. The following command retrieves the log files of all "Done" jobs of the last created CRAB project. The job results will be copied in the res subdirectory of your crab project ( for example crab_0_110702_181826):

crab -getoutput

When you execute this command you should see an output should look like:


crab:  Version 2.7.8 running on Fri Jul  1 10:06:14 2011 CET (08:06:14 UTC)

It may happen that while doing crab -getoutput, your disk quota gets exceeded. In that case you will not be able to look at the log files of all the jobs.

If you succeed in getting crab -getoutput of however many jobs that got done, your crab_0_110702_181826/res should have all the log files and look like the output below. Note. Let us say jobs 1 to 50 and 60 to 70 and 95 are done and you do not want to wait till all the jobs are done, you can get their output by doing crab -getoutput 1-50,6-70, 95

Step 10 - Check log files to trace problems, if any

You can look at the log files in crab_0_110702_181826/res directory after executing the above step to see the details in case a job fails.

You can also print a short report about the task, namely the total number of events and files processed/requested/available, the name of the dataset path, a summary of the status of the jobs, and so on. A summary file of the runs and luminosity sections processed is written to res/. In principle -report should generate all the info needed for an analysis. To get a report execute the following. Note in this case 1 job out of 495 jobs did not execute.

crab -report

The output of this command should look like something like this ( this is an old cut and paste, but conveys the message):

crab:  Version 2.7.8 running on Fri Jul  1 09:59:55 2011 CET (07:59:55 UTC)

crab. Working options:
        scheduler           glite
        job type            CMSSW

        working directory   /afs/cern.ch/user/m/malik/scratch0/PAT2011JULY/CMSSW_4_2_4/src/crab_0_110630_103547/

Log file is /afs/cern.ch/user/m/malik/scratch0/PAT2011JULY/CMSSW_4_2_4/src/crab_0_110630_103547/log/crab.log

If you want to publish your output to DBS, you need to re-run your CRAB job with modification of some option. Please see here for more details.

Step 10 - Open an output root file to make sure you see the plots of variables.

Make sure to open a root file to see if it contains what you wnanted. Once you have your output root files, you are ready to analyze them.

To open a root file from your castor storage area, do as follows ( as an example, replace path name and root file name to what you actually have in your area)

root -l /castor/cern.ch/user/m/malik/pattutorial/jet2011A_AOD/jet2011A_aod_89_0_Afy.root

ALERT! Note:

If you are doing this exercise in the context of the PAT Tutorial course in case of problems don't hesitate to contact the SWGuidePAT#Support. Having successfully finished Exercise 4 you might want to proceed to Exercise 5 to learn how to access the pat::Candidate collections that you just produced within an EDAnalyzer or within an FWLite executable. For an overview you can go back to the WorkBookPATTutorial entry page.
