I'm using -bind-to-core without any other options (default is -bycore I

These numbers indicate number of cores first, then the second digit is the run

I am having a weird problem launching cases with OpenMPI 1.4.3. It is most
likely a problem with a particular node of our cluster, as the jobs will run
fine on some submissions, but not other submissions. It seems to depend on the
node list. I just am having trouble diagnosing which node, and
ion. If so, you could do:
mpirun -npersocket 2 -bind-to-socket ...
That would put two processes in each socket, bind them to that socket, and rank
them in series. So ranks 0-1 would be bound to the first socket, ranks 2-3 to
the second.

Thanks, Ralph,
I get the failure messages, unfortunately:
setgid FAILED
setgid FAILED
setgid FAILED
I actually had attempted to call setgid from within the application previously,
which looks similar to what you've done, but it failed. That was when I
initiated the post to the mailing list. My

I'm able to run this command below from an interactive shell window:
/bin/mpirun --machinefile mpihosts.dat -np 16 -mca plm_rsh_agent
/usr/bin/rsh -x MPI_ENVIRONMENT=1 ./test_setup
but it does not work if I put it into a shell script and 'qsub' that script to
SGE. I get the message shown at th
sue might be, but I would check for a typo - we don't check
that mca params are spelled correctly, nor do we check for params that don't
exist (e.g., because you spelled it wrong).

I have a hello world program that runs without prompting for password with
plm_rsh_agent but not with orte_rsh_agent, I mean it runs but only after
prompting for a password:
/bin/mpirun --machinefile mpihosts.dat -np 16 -mca plm_rsh_agent
/usr/bin/rsh ./test_setup
Hello from process

Things work fine on 480, and I don't think the application has a bug. Any help
is appreciated...
