Pawel:
One of the enhancements present in mvapich-1.0.1 over 0.9.9 is a new
interface for the mpirun_rsh process manager that allows us to bootstrap
mvapich programs in a more scalable manner.  Because of this change in
interface your mvapich-0.9.9 mpi programs cannot be launched by the
mvapich-1.0.1 mpirun_rsh and would require a recompilation.
