Thanks Utkarsh. Just to add to this thread, I asked some of the OMPI
developers and apparently it's not possible to avoid this behavior.

Yup, that's expected. That's because of your MPI implementation.
OpenMPI does a busy wait when waiting for mpi messages. I think
there's an environment variable or something that you can set to
disable that, I am no sure. Maybe someone on the mailing list knows,
or try checking the OpenMPI documentation.

When I use 'mpirun -np 2 pvserver' on my dual core MacBook (either
connecting to it via paraview client or standalone), it keeps one of
my CPUs pegged at nearly 100%. Is this to be expected? (Just
running the serial './pvserver' of course just generates
'Listening...Waiting for client...' with no CPU load).
% ./pvserver --version
ParaView3.7
% ompi_info
Open MPI: 1.3.1
thanks, Randy
