[Condor-users] wrapping an MPI executable

[Rok Roskar <roskar@xxxxxxxxxxxxxxxxxxxx>]

I am currently running MPI programs through condor. Our code does a 
form of checkpointing, but I need to run a script after the process 
finishes, which sets up the files for a later restart. So, I would like 
to be able to wrap my MPI executable in a script, so that I can run 
some scripts before condor starts up the main MPI program. Is there 
some way to do this? Does condor invoke some sort of 'mpirun' command 
when it starts up MPI jobs? In that case, putting the executable in a 
script probably won't work. Is there some other way to tell condor to 
run something else before actually starting the process? thanks,

rok
