Using PROOF

From ATLAS-TRIUMF

Jump to: navigation, search

Some of the machines at TRIUMF have been configured as a PROOF cluster but to use this, you will need an account. Details on how this was installed are in another page; here, we only describe how to run a test job.

Note that this is still "cutting-edge" technology and there are a few known bugs.

The simplest way to run a job is to download the tar file (courtesy of Neng Xu at U. Wisconsin) and unpack it somewhere in your directory. The tar file can be found in CVS] and is named PROOF_test_TRIUMF.tar.gz.

1. First, you will need to upload your datafile; eg:

xrdcp proof_test._00001.root root://atlas-tier3-c1.triumf.ca///datalocal/proof/proofpool/
xrdcp proof_test._00002.root root://atlas-tier3-c1.triumf.ca///datalocal/proof/proofpool/

You may not need to do this step if someone else has already done it and the files exist.

2. Next, edit the file run.C and make the appropriate changes as suggested in the comments.

3. Run ROOT (you can setup from your ATLASLocalRootBase installation)

     root -l

4. Run the test

     .x run.C
