I imagine you must have a system admin down there - perhaps you should ask for
their help in finding the OMPI installation. Such systems often use "modules"
to assist in setting up paths. I'm afraid I can't really help you find it, all
I can do is tell you that you are using the MPICH version.
It returns /usr/bin/mpiexec.

Do "which mpiexec" and look at the path. The options you show are from MPICH,
not OMPI.

Hi Ralph,
Thanks for your reply.
I am not pretty sure about the version of mpiexec. The documentation claims
that two mpi are installed, namely, OpenMPI and MPICH2.

No, it doesn't matter at all for OMPI - any order is fine. The issue I see is
that your mpiexec isn't the OMPI one, but is from someone else. I have no idea
whose mpiexec you are using

I have found the solution. The command *mpirun -machinefile ./my_hosts -n 3
./testMPI* works. I think the order of arguments matters here.

Hi all,
I got problem with running program on a cluster.
I used the following command. *my_hosts* is a file containing 3 hosts while
*testMPI* is a very simple MPI program.
==
*mpirun -np 2 --hostfile ./my_hosts ./testMPImpirun -np 2 --machinefile
./my_ho
