In theory, the candidate Boost.MPI should work with any MPI that
meets the MPI 1.1 specification. In practice, we tend to test with
those three implementations.

You'll need a modern C++ compiler to use the candidate Boost.MPI. It
should be platform-agnostic, but again--we only typically test a few
platforms, namely x86 Linux, x86-64 Linux, and PowerPC Mac OS X.

Although we have yet to run the tests with the candidate Boost.MPI,
we ran NetPIPE numbers using a prototype of the same C++ interface.
There was no impact on either bandwidth or latency.

I know there are a few Boosters that are in the HPC/parallel
computing area. I'm also planning to strong-arm whatever MPI experts
I can find :)
