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 director

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
Agreed.
How could I forget to mention mpirun?! :(
I don't know what Jorge is trying to achieve,
but with mpirun it is easy to launch multiple copies of
serial programs, or different serial programs,
with command line options such as this:
mpirun -np 1 --host a hostname : -np 2 --host b,c uptim
If that is what you are trying to do, mpirun will do it just fine too - it
doesn't have to be an MPI program.

Besides what Reuti and Eugene said, in case what you're looking for
is a mechanism to launch several copies of a
serial [non-parallel] program in a cluster,
you could try these alternatives:
1) Launch several jobs to run the same program,
using a job scheduler like Torque or Grid Engine.

correct.

Maybe someone else on this list has a better idea what you're trying to
do, but I'll attempt to answer your question.
MPI is basically a set of library calls that can be used for processes
to communicate with one another. Of course, a program need not have any
MPI calls in it, but if you want
Hello everyone, I have a doubt about how to execute a parallel application
on a cluster. I used the 'mpirun' to execute some applications and they
worked, but I guess this command only is useful with MPI applications. My
question is, How do I execute a program that has no MPI statements on the
clus
