I've been trying to get OpenMPI working on two of the computers at a lab I help administer, and I'm running into a rather large issue. When running anything using mpirun as a normal user, I get the following output:
$ mpirun --no-daemonize --host localhost,localhost,localhost,localhost,localhost,localhost,localhost,localhost /workspace/bronke/mpi/hello mpirun noticed that job rank 0 with PID 0 on node "localhost" exited on signal 13. [trixie:18104] ERROR: A daemon on node localhost failed to start as expected. [trixie:18104] ERROR: There may be more information available from [trixie:18104] ERROR: the remote shell (see above). [trixie:18104] The daemon received a signal 13. 8 additional processes aborted (not shown) However, running the same exact command line as root works fine: $ sudo mpirun --no-daemonize --host localhost,localhost,localhost,localhost,localhost,localhost,localhost,localhost /workspace/bronke/mpi/hello Password: p is 8, my_rank is 0 p is 8, my_rank is 1 p is 8, my_rank is 2 p is 8, my_rank is 3 p is 8, my_rank is 6 p is 8, my_rank is 7 Greetings from process 1! Greetings from process 2! Greetings from process 3! p is 8, my_rank is 5 p is 8, my_rank is 4 Greetings from process 4! Greetings from process 5! Greetings from process 6! Greetings from process 7! I've looked up signal 13, and have found that it is apparently SIGPIPE; I also found a thread on the LAM-MPI site: http://www.lam-mpi.org/MailArchives/lam/2004/08/8486.php However, this thread seems to indicate that the problem would be in the application, (/workspace/bronke/mpi/hello in this case) but there are no pipes in use in this app, and the fact that it works as expected as root doesn't seem to fit either. I have tried running mpirun with --verbose and it doesn't show any more output than without it, so I've run into a sort of dead-end on this issue. Does anyone know of any way I can figure out what's going wrong or how I can fix it? Thanks! -- David H.
