can you run a non-MPI job on the cluster?
if so, does it work ok or also dies?

are you using a batch scheduler? if so, sometimes
the error messages may go into an output file
created by the scheduler. run it interactively and
you get errors messages and also you can be sure
your working directory is correct, with schedulers
you need to set it.
