I believe what you are looking for is how to setup Atlas Local Root Base (ALRB),
which lives within the CVMFS repository atlas.cern.ch?

As part of your job, you can setup ARLB and ROOT with the following commands

export ATLAS_LOCAL_ROOT_BASE=/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase
source $ATLAS_LOCAL_ROOT_BASE/user/atlasLocalSetup.sh
localSetupROOT --skipConfirm


I have some documentation and sample scripts that might help you with this at

http://twiki.mwt2.org/bin/view/Main/RCCSubmitIntoMWT2#Setting_up_a_working_environment

There is an example as to how to import a grid proxy, setup ARLB, etc

If you would like to see other examples, please let me know.

One item I should document is how to steer a job to a specific site (in this case MWT2 or Fresnostate)
You can use a requirement in your condor submit file which selects this

If you use the appropriate requirement in your condor submit file, your job will only run at MWT2 or Fresnostate

Requirements            = ( IS_RCC_mwt2 )
Requirements            = ( IS_RCC_fresnostate )

Perhaps it would also be useful if I automatically defined an environment variable when your job runs
that tells which  which site your job is at.  Then you could check in your script with something like

[[ $IS_RCC_mwt2 ]] && echo "Running at MWT2"

If that would be useful, it is very easy for me to add.

thanks, dave

Hello,

Is there any documentation as How ROOT can be setup in MWT2. I ran few basic jobs which is simple C code, it distributed and runs fine over the MWT2, FresnoT3

Now, What I am thinking is if I try to submit simple condor job which uses 1 rootfile and fetch say number of entries in a cutflow or any histogram. I need to take that 1 rootfile over number of nodes where my job runs. 

Then Setup the ROOT and fetch the ouput.

I know how to setup the Root in my nodes but dont know about MWT2. Could you give me directions if I can setup ATLAS environment in MWT2 cluster(ROOT automatically come inside that environment)

AM I thinking reasonably?:)

PS:
