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)
  Host: n06

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

Does anyone know why these messages appear and how to fix this.
