Using SLIC from lxplus

When simulating events with slic it is always advised to do this as a batch job, like on the CERN lxplus batch queues.

For easy submission of multiple jobs to the batch queues (splitting the job for parallel processing) a script has been set up:

script usage

  • connect to an lxplus machine using your CERN account
    ssh lxplus
  • run the script with the according parameters
    ./ -...
  • the possible parameters are:
    • -h or --help : lists all possible parameters with a short description
    • -a ANGLE: sets the opening angle for the point-like particle source (default=1)
    • -d DETECTORNAME: sets the name of the detector to be used (default=clic000)
      the script also checks if the necessary detector description is located at /afs/
    • -e ENERGY : sets the particle energy (in GeV) for all particle sources except stdhep input (default=50)
    • -f FILENAME : sets the file name of the stdhep input file
    • -g GENERATOR : sets the particle generator, this parameter is mandatory. It can be
      • file for stdhep input
      • beam for a testbeam-like particle generator
      • gun for particles generated in a straight line
      • point for a point-like particle generator
    • -j JOBS : sets the number of equal jobs to be submitted (default=1)
      for stdhep input the jobs are sequentially, ie. job1 will simulate events 0-99, job2 will simulate events 100-199, ...
    • -l PHYSLIST : sets the physics list to be used (default=QGSP_BERT)
    • -n NEVENTS : sets the number of events per submitted job (default=100)
    • -p PARTICLE : sets the particle type for all particle sources except stdhep input (default=pi+)
      important : use the GEANT4 particle naming convention
    • -q QUEUE : sets the lxplus batch queue
      this has to be one of the following: 8nm, 1nh, 8nh, 1nd, 2nd, 1nw, 2nw
