Basic scripts to submit jobs to CERN batch system. If you will modify scripts, remember, that HTCondor Docker universe DOES NOT work with /afs, only /eos.

How to:

  • define EOS_DIR, CONDOR_ROOT in set_global_envs.sh. Define geometry file and directory where you want to save results on EOS by setting PRODUCTION_FOLDER and MAGNET_GEO in set_paths_flux.sh.
  • source set_global_envs.sh && source set_paths_flux.sh
  • mkdir $CONDOR_ROOT/error $CONDOR_ROOT/output $CONDOR_ROOT/log (this need to be done only once)
  • python3 generate_dag_file.py
  • condor_submit_dag -force dag_submit.tmp.

By default DAG submission resume from the checkpoint, which can result into jobs failures, thus we explicitly say to run jobs from scratch: -force

How to use:

Step 1

Set up variables names, used during submission. EOS_DIR is your usual username EOS folder. CONDOR_ROOT is the folder where you want HTCondor to write output, error and log messages. MAGNET_GEO_FULL_PATH is the shield geofile you want to test. For example, MAGNET_GEO_FULL_PATH=/eos/experiment/ship/data/magnet_geofiles/magnet_geo_to_test_oliver.root. It must be an absolute path to the file. MAGNET_GEO is determined automatically, do not change it. PRODUCTION_FOLDER is where the whole output will be written on the EOS, i.e. all output will be saved at EOS_DIR/PRODUCTION_FOLDER.

Step 2

Set the variables above.

Step 3 (important)

Create folders for log/output/error logs. This is important to do, otherwise you jobs might stuck idle forever!

Step 4

Generate DAG submission file. It will created jobs to process 67 muon. It will subsequently run sim.sub->flux.sub and in the and will create final output file of the flux in the EOS_DIR/PRODUCTION_FOLDER.

Step 5

Submit jobs to cluster.

In the end, you should have the follwoing output structure

EOS_DIR/PRODUCTION_FOLDER
