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@linux-hldu:~> mpirun -host Frank@158.110.39.110 hostname Password: francesco@linux-hldu:~> If I request debug, the result is: francesco@linux-hldu:~> mpirun -d --host Frank@158.110.39.110 hostname [linux-hldu.site:02537] sess_dir_finalize: job session dir not empty - leaving [linux-hldu.site:02537] procdir: /tmp/openmpi-sessions-francesco@linux-hldu_0/33429/0/0 [linux-hldu.site:02537] jobdir: /tmp/openmpi-sessions-francesco@linux-hldu_0/33429/0 [linux-hldu.site:02537] top: openmpi-sessions-francesco@linux-hldu_0 [linux-hldu.site:02537] tmp: /tmp Password: [linux-o5sl.site:04273] sess_dir_finalize: job session dir not empty - leaving [linux-o5sl.site:04273] procdir: /tmp/openmpi-sessions-Frank@linux-o5sl_0/33429/0/1 [linux-o5sl.site:04273] jobdir: /tmp/openmpi-sessions-Frank@linux-o5sl_0/33429/0 [linux-o5sl.site:04273] top: openmpi-sessions-Frank@linux-o5sl_0 [linux-o5sl.site:04273] tmp: /tmp [linux-o5sl.site:04273] sess_dir_finalize: job session dir not empty - leaving exiting with status 1 [linux-hldu.site:02537] sess_dir_finalize: job session dir not empty - leaving exiting with status 1 Do you understand where is the problem? How can I get more information? Thank you for your cooperation regards Francesco
