this sort of thing is not uncommon - I normally recommend that the user
submit a script which does the setup step, then mpirun's the parallel code.
this wastes some cycles (the setup is normally serial, so wastes n-1 cpus
for that duration.) alternatively, submitting a serial setup job followed
by a (dependent) parallel job makes sense but incurs more queue time.
