If the perror command is available on your system it will tell
you what the message is associated with the signal value. On my system
RHEL4U3, it is permission denied.

Subject: [OMPI users] Signal 13
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
$ mpirun --no-daemonize --host
mpirun noticed that job rank 0 with PID 0 on node "localhost" exited on
[trixie:18104] ERROR: A daemon on node localhost failed to start as
[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
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:
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?
