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

In MadGraph5, a list of cluster are supported internally.
In the file input/mg5_configuration.txt
you have the list of available cluster 
and the option to configure those.

You can add/edit those cluster to fit your need. More information on that on this link:
https://answers.launchpad.net/madgraph5/+faq/2249





== MadGraph4 information

=== If you have a ''central'' data disk ===
The current MadGraph / 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 MadGraph / 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.
