Dear all,
thanks a lot. So basically the idea is that MPI is more useful when a lot
of communication occurs in the calibrator. On the other hand, the jobs
scheduler is more appropriate when there are no or few communications.
Is my final statement correct?
Thanks a lot

Diego,
what you wont to do is parametric studies. There are specific software available
to do this efficiently (ie reducing the number of runs). Software can then rely
in a job scheduler (PBS, SLURM...) which can launch many parallel mpi
applications at the same time depending on the results
Hi Diego
I (still) have Torque/PBS version 4.something in old clusters.
[Most people at this point already switched to Slurm.]
Torque/PBS comes with a tool named "pbsdsh" (for PBS distributed shell):

Dear all,
thank you for your answers. I will try to explain better my situation.
I have written a code and I have parallelized it with openMPI. In
particular I have a two level palatalization. The first takes care of a
parallel code program and the second run the parallel code with different

It depends on the code in
Diego,
I am sorry but you have different things here. PBS is a resource allocation
system. It will reserve the use of a compute server, or several compute
servers, for you to run your parallel job on. PBS can launch the MPI job -
there are several mechanisms for launching parallel jobs.
MPI is an

To parallelize their code? I would more phrase it: "Using a
Dear all,
I have a philosophical question.
I am reading a lot of papers where people use Portable Batch System or job
scheduler in order to parallelize their code.
What are the advantages in using MPI instead?
I am writing a report on my code, where of course I use openMPI. So tell me
please
