== 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 (pavel.demin_AT_uclouvain.be) for more information on this.
