The use of mpirun_rsh is recommended for faster and scalable job
start-up.  One can use the MPD/mpiexec functionality. However, this will
not be scalable. Most of MVAPICH/MVAPICH2 users currently use the
mpirun_rsh framework. The MPD/mpiexec feature can be used with MVAPICH2.
However, it may have performance bottlenecks. We plan to add additional
features to mpirun_rsh in future releases.
