Running Software.MadGraph / Software.MadEvent in the parallel mode on your own cluster

If you have a central data disk

The current Software.MadGraph / Software.MadEvent version assumes all the scripts are ran from a central data disk mounted on all cluster nodes (e.g. a home directory). If you have access to such a central disk, read the following. If not, please refer to the last section. Some scripts may assume the existence of a specific queue called madgraph. If you have difficulties with these, simply create this queue on your cluster (this can help to limit the number of CPU for example), or remove the =-q madgraph= options in the run_XXX scripts located in bin.

If you have a PBS-compatible batch managing system (PBSPro, !OpenPBS, Torque, ...)

This is the easiest case since the default configuration should work out of the box using the qsub command (and qstat and/or qdel if the whole web interface is present). There is nothing special to do, just run the generate_events script as usual and select parallel mode.

If you use the Condor batch managing system

A "translation" script exists (see attachments of this page) to emulate the qsub command using a Condor syntax. This script should be tuned to fit your Condor installation and put in a directory of the =$PATH= variable.

If you use another batch managing system

This is the most complicated case, you can either:

  • Modify manually the survey, refine and run_XXX scripts located in the bin directory to force them to use your submission system.
  • Write a "translation" script like the one available for Condor (see attachment) to emulate the qsub command. If you manage to do this and want to share your script to help other Software.MadGraph / Software.MadEvent users, please feel free to edit this page.

If you do not have a central data disk

We are aware the central disk solution may be inefficient or even impossible to set up on large clusters. We are thus working on a permanent solution. In the meantime, an intermediate solution using temporary directory and the scp command exists. Please contact directly Pavel Denim ( for more information on this.
