I'm assuming you are talking about the mpiexec utility provided by Ohio Supercomputer Center. It does provide better integration between either LAM or MPICH and PBS. The upside is that it speeds startup times slightly and allows slightly better (but not perfect) end-of-job cleanup. The downside is that you may have to rebuild the MPI implementations and the interface isn't the standard LAM or MPICH interface. mpiexec seems better suited for large installations. For smaller ones, it probably isn't worth the hassle of installing. At least, that's my $0.02.
