So if our application is linked with mpichgm but our user has mpich for 
ch_p4 installed or has no mpi installation at all, is it advised to 
distribute the mpirun script (of our mpichgm installation) with our 
application? If yes, what exactly do we need to distribute (only the 
mpirun script or more) ?

Thanks for the help,
