Hello,
For several years I have successfully used MPIIO in a Fortran global
atmospheric ensemble data assimilation system. However, I always
wondered if I was fully exploiting the power of MPIIO, specifically by
using derived data types to better describe memory and file data
layouts. All of my
Yeah, we aren't connecting back - is there a firewall running? You need to
leave the "--debug-daemons --mca plm_base_verbose 5" on there as well to see
the entire problem.
What you can see here is that mpirun is listening on several interfaces:

Here it is:

$ mpirun -mc
I found no option in 1.6.5 and 1.8.1...

I'm unaware of any CentOS-OMPI bug, and I've been using CentOS throughout the
6.x series running OMPI 1.6.x and above.
I can't speak to the older versions of CentOS and/or the older versions of OMPI.

Try adding -mca oob_base_verbose 10 -mca rml_base_verbose 10 to your cmd line.
It looks to me like we are unable to connect back to the node where you are
running mpirun for some reason.

I have the same problem in openmpi 1.8.1( Apr 23, 2014 ).
Does the srun command have a --map-by mpirun parameter, or can i chage it
from bash enviroment?

Hello everyone,
I am trying to get the maximum performance out of my two node testing
setup. Each node consists of 4 Sandy Bridge CPUs and each CPU has one
directly attached Mellanox QDR card. Both nodes are connected via a
8-port Mellanox switch.
So far I found no option that allows binding m

No - we don't kill any processes. We just tear down the MPI system. All your
processes continue to execu
Dear all,
I have a question about mpi_finalize.
After mpi_finalize the program returs single core, Have I understand
correctly?
In this case I do not understand something:
In my program I have something like:
call MPI_FINALIZE(rc)
write(*,*) "hello world"
However, my program write it many times
