If you don't want to pay money for an MPI, then go with Open-MPI. It too can run on various networks without recompiling. Plus it's open-source.
Unless you are using a gigabit ethernet, Open-MPI is noticeably less efficient that LAM-MPI over that fabric.
I suspect at some point in the future gige will catch-up but for now my (limited) understanding is that the Open-MPI folks are focusing their time on higher bandwidth/lower latency fabrics than gige.
