I think it might be useful to link that from the Boost.MPI docs, too.
While the library seems nice (it bridges serialization with MPI), I don't really see anything in there that makes me think it's "so cool".
So after reading it, I felt a bit like the question "What's so cool about Boost.MPI?" remained unanswered.
The semi-automatic, but very easy to maintain, way of creating/maintaining the MPI type maps (via Boost.Serialization), IIUC. -Thorsten

Take it from someone who had to wrestle with MPI with the C interface, what's so cool about Boost.MPI is really that it's idiomatic to use with C++ semantics. If you ever tried to use the C MPI interface directly you will see how much of a joy to use Boost.MPI is. But really, don't take my word from it, try it out and see for yourself. -- Dean Michael Berris deanberris.com

Which yields huge performance benefits and makes practical some computations that might otherwise not be, due to resource constraints and the difficulty of generating type maps for arbitrary data structures. Do I need to be more explicit about that, or is it simply “not that cool?” -- Dave Abrahams BoostPro Computing http://www.boostpro.com
