Subject: [OMPI users] can't run mpi-jobs on remote host

Dear MPI users,

I have a problem with open-mpi (version 1.8).

I'm just beginning to undestand how mpi works and I can't find solution of my problem on FAQ page.

I have two machines (a local host and a remote host) with linux open-suse (latest version) and open-mpi 1.8

I can run open-mpi jobs on both machines from theirself (in a "local" way).

I have not connections problem: ssh from the first to the second works correctly and I can run programs on remote machine.

If I run a simple non mpi program on the remot host from the local one, it doesnt' work. I think it is a buffer pointer problem (status 1). I didn't change open-mpi settings and PATH is correct. I have just one open-mpi versione on both of them. Open-mpi doesn't show any error: just return to the local machine.

I can also request to run a false program: it does not change. on the terminal I can read

francesco_at_linux-hldu:~> mpirun -host Frank_at_158.110.39.110 hostname

If I request debug, the result is:

francesco_at_linux-hldu:~> mpirun -d --host Frank_at_158.110.39.110 hostname

Do you understand where is the problem? How can I get more information?

Thank you for your cooperation
