Hi Josh,
Thank you for your replying.
I tried to patch a Ticket #2139 to openmpi-1.4.1
and to install all of the elements from the very beginning.
Then I got a correct work.
Probably there are some faults on my environment preparation.
# I cannot reproduce the environment when I got failure.

Try running with:
mpirun.openmpi-1.4.1 --mca btl_base_verbose 50 --mca btl self,openib -n 2
--mca btl_openib_verbose 100 ./IMB-MPI1 -npmin 2 PingPong
Also, are you saying that running the same command line with osu_latency works
just fine? That would be really weird...

I've noticed that ompi-restart doesn't support the --rankfile option.
It only supports --hostfile/--machinefile. Is there any reason

The functionality of checkpoint operation is not tied to CPU
utilization. Are you running with the C/R thread enabled? If not then
the checkpoint might be waiting until the process enters the MPI
library.
Does the system emit an error message describing the error that it

That's correct. I have prefixed them with OMPI_MCA_ when I defined them
in my environment. Despite that I still see some of these files being
created under the default directory /tmp which is different from what I
had set.

When you defined them in your environment did you prefix them with
'OMPI_MCA_'? Open MPI looks for this prefix to identify which
parameters are intended for it specifically.

So I recently hit this same problem while doing some scalability
testing. I experimented with adding the --no-restore-pid option, but
found the same problem as you mention. Unfortunately, the problem is

BLCR will restart the process with a new PID, but the value ret
Starting in the 1.3 series, you have to tell OMPI where to find the default
hostfile. So put this in your default MCA param file:
orte_default_hostfile=
That should fix it.

Could you tell us what version of OMPI you are using?
Thanks

Hello,
I manage a little HPC-Cluster.
It seams like the default-hostfile is located in /etc/openmpi.
But when i write my hosts in it, it isn't used by mpirun.
How can i use an default hostfile?

Hello,
trying to run Intel MPI Benchmarks with OpenMPI 1.4.1 fails in initializing
the component openib. System is Debian GNU/Linux 5.0.4.
The command to start the job (under Torque 2.4.7) was:
mpirun.openmpi-1.4.1 --mca btl_base_verbose 50 --mca btl self,openib -n 2
./IMB-MPI1 -npmin 2 PingP
