Dear All,
I have installed openmpi 1.3.2 on one on the nodes of
our cluster and is running a simple helloword mpi program. The program
runs fine but I get a lot of unexpected messages in between the result.

[[11410,1],1]: A high-performance Open MPI point-to-point messaging module
was unable to find any relevant network interfaces:
Module: OpenFabrics (openib)

Another transport will be used instead, although this may result in
lower performance.

You can define some default parameter in the
$OMPIDIR/etc/openmpi-mca-params.conf
For instance, you can add :
# Exclude openib BTL, not currently supported
btl = ^openib,ofud
