MPI by Sun

Since we’ve been discussing MPI, I thought I’d mention that Sun is again supporting MPI.

For reasons too incredible to believe, Sun neglected to move its MPI package to Solaris 10, or to X64. After a nudge and a bit of funding from the HPCS program, they are fixing that. This is one of the best MPI implementations anywhere, and certainly the best on Sun systems. It can take full advantage of shared memory when it’s available.

It’s part of ClusterTools, which is now available for early access. It’s also available as open source using the Sun Community Source License.

Get it and try it out. If you have any problems, report them. The developers are a good crew, and will do their best to make you happy with it.
