[MPICH] Question about MPICH2 on a single machine

[Rajeev Thakur]

You should try out the recently released version 1.0.3. With mpd, you need
to do "mpd &" before running "make testing". If any errors occur at that
point, let us know.

You can use "mpiexec" to run an MPI program instead of mpirun.
