CRAB @ FNAL

1.) Set up environment

 
source /uscmst1/prod/grid/CRAB/crab.csh
voms-proxy-init -voms cms

2.) Modify the CRAB configuration file "crab.cfg" (template available at $CRABDIR/python/crab.cfg)

crab -create -cfg crab.cfg

to create jobs that can be submitted to remote machnines.
3.) Make directory on the file server to store the output files. Also set permission 775, i.e., group-writable.

mkdir /pnfs/cms/WAX/resilient/kalanand/trash
chmod +775 /pnfs/cms/WAX/resilient/kalanand/trash

At CERN

rfmkdir /castor/cern.ch/user/u/kalanand/trash
rfchmod +775 /castor/cern.ch/user/u/kalanand/trash

4.) Now subit the above created jobs and check status

crab -submit -c < dire_name>
crab -status -c < dire_name>
crab -getoutput all -c < dire_name>

5.) Other options:

crab -kill 1 -c < dire_name>

where "1" can be replaced with any combination of job numbers and job ranges separated by comma (e.g., 1, 2, 3-8).

crab -resubmit 1 -c < dire_name>
crab -clean all -c < dire_name>

6.) For CRAB error exit codes please see https://twiki.cern.ch/twiki/bin/viewauth/CMS/JobExitCodes

To submit jobs to condor queue via crab:

step 0: In the crab.cfg file (in the [CRAB] section), set the scheduler to condor:

       scheduler = condor

step 1: Do the following:

       echo "source /uscmst1/prod/sw/cms/shrc prod" > ~/.profile

step 2: Set up your grid proxy:


       voms-proxy-init -voms cms

Step 3: Set up the environment:

       source /uscmst1/prod/grid/gLite_SL5.csh
       source /uscmst1/prod/grid/CRAB/crab.csh

Now follow the above instructions to run a crab job.

To compile a C++ file natively on my Mac outside of ROOT

Suppose the name of the file is myCppFile.C. Then to compile it, I would do

make myCppFile

To run this compiled file:

./myCppFile

To run ROOT in batch/background mode

root -b -q myMacro.C+ >& a.log &

The "-b" runs in match mode, "-q" exits ROOT after running the macro.

How to create a CVS branch

cvs tag -b < new_branch_name>
cvs update -r < new_branch_name>

The above commit command has the same effect as the following:

cvs commit -r < new_branch_name>
