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.
I don't think we handle this:

You need to have only one -H option - use comma to separate the values

Hi,
I am trying to run osu mpi benchmark tests on Infiniband setup (connected
back-to-back via Mellanox hw). I am using the below command
"mpirun --prefix /usr/local/ -np 2 --mca btl openib,self -H 192.168.4.91 -H
192.168.4.92 --mca orte_base_help_aggregate 0 --mca btl_openib_cpc_include oob

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
Right !
that's the problem when you work on someone else code.
Thanks

Hello
I'm extending a code currently working well on a server with some
quadri-core.
But for debugging purpose i want to execute it on my local computer.
When i use the command :
mpirun -np 6 -host local ./execFile
i get an :
ERROR: too many MPI processes
i've tried other mpi programs,
Well, you asked for two processes, and your hostfile indicates that we can run
two procs on each machine. So we put those two procs on the first machine,
leaving nothing for the second machine to do.
If you want the procs on different machines, then add -bynode to the cmd line.
This will put on
12 matches
