Myrinet makes especially sense, if you are willing to use a zero-copy protocol like MPI-BIP instead of MPI/TCP-IP or BIP instead of TCP/IP, you'll get a lot greater bandwidth and less latency. Maybe checkout the MPI-BIP Homepage http://lhpca.univ-lyon1.fr and the performance of Torc (http://www.netlib.org/utk/projects/torc/perform.html) here at Knoxville for comparsion.
