Currently submitting co-allocated MUSCLE application is only possible using the XML !JobProfile (compare [[QCG-SimpleClient]]). Beside the different job description format you have to suffix the `qcg-sub` command with the `QCG` keyword:
{{{
$ qcg-sub muscle.xml QCG
}}} 
== Example (Fusion - Transport Turbulence Equilibrium) ==
 * Install your application on every cluster you wish to use
 * register it on every cluster using [http://apps.man.poznan.pl/trac/qcg-computing/wiki/ComunityModules QCG Community Modules (QCE)] mechanism:
{{{
qcg-module-create -g plggmuscle Fusion/Turbulence
}}}
The module must bear the same name on every cluster. Inside the module you can set/prepend any environment variable, add dependencies to other modules, e.g.:
{{{
#%Module 1.0


proc ModulesHelp { } {
        puts stderr "\tName: Fusion/Turbulence"
        puts stderr "\tVersion: 0.1"
        puts stderr "\tMaintainer: plgmamonski"
}

module-whatis   "Fusion/Turbulence, 0.1"

#add path to the native MUSCLE kernels
prepend-path PATH /home/plgrid-groups/plggmuscle/fusionkernels/bin/

set curMod [module-info name]

if { [ module-info mode load ] } {
        puts stderr "$curMod load complete."
}

if { [ module-info mode remove ] } {
        puts stderr "$curMod unload complete."
}
}}}
You can set there two environment variables interpreted by the MUSCLE framework:
 * MUSCLE_CLASSPATH
 * MUSCLE_LIBPATH
to set Java classpath and the path of dynamically loadable libraries. Thanks to this mechanism you can use single abstract CxA that do not contain any site-specific paths. Also you can load the module in interactive QCG job:
{{{
bash-4.1$ module load Fusion/Turbulence
Fusion/Turbulence load complete
}}}
* Prepare XML job description:
