Hi,
We are having problems with OpenMPI 1.6.3 - it gives the below error message
when trying to run:
$ mpirun -np 32 ./mpi_test.x
--------------------------------------------------------------------------
WARNING: It appears that your OpenFabrics subsystem is configured to only allow
registering part of your physical memory. This can cause MPI jobs to run with
erratic performance, hang, and/or crash.
This may be caused by your OpenFabrics vendor limiting the amount of physical
memory that can be registered. You should investigate the relevant Linux
kernel module parameters that control how much physical memory can be
registered, and increase them to allow registering all physical memory on your
machine.
See this Open MPI FAQ item for more information on these Linux kernel module
parameters:

Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error

Openmpi 1.4.3 works fine.
Any help would be greatly appreciated.
Thanks,
