Hi Jorge
Aha! A serial executable. I guessed it right! :)
But Ralph certainly came up with the simpler solution: use mpirun.
As for the other question:
If you are using Torque/PBS to launch the job,
put this line in your PBS script:
cd $PBS_O_WORKDIR
which will put you in the work directory on all nodes
(assuming that directory is NFS mounted as you said).
If you are launching mpirun directly, use the -path option,
to specify the full path of your executable.
Actually, the best thing is to read carefully 'man mpirun',
to get the details right.
[Make sure you're reading the *OpenMPI mpirun* man page,
not from another MPI flavor.]
Good luck!
My two cents,
Gus Correa

Thanks for all your suggestions.
Yes, indeed what I'm trying to do is execute a serial program. All the
documentation you mention was pretty useful.
I have another question, if mpirun launches several copies of the
program on the different hosts, does it mean that I must have a copy of
the program on all the nodes, because I'm using NFS to share the
location were my program is installed and it seems to work fine when I
execute mpirun with simple scripts.
Jorge.
