Hi,
        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.

HTH,

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
output:

$ mpirun --no-daemonize --host
localhost,localhost,localhost,localhost,localhost,localhost,localhost,lo
calhost
/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,lo
calhost
/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!
