Hi Doug, I'm just thinking aloud here: This might not be directly related, but will the candidate Boost MPI implementation implement the common parallel architectural patterns (like meshes, lattices, trees, rings, and manager-worker/master-slave, among others), using generative techniques (or even template metaprogramming) to perhaps make the common solutions readily usable "out of the box" ? It might be a good value add over the other C++ wrappers to MPI implementations, but I guess at this point getting the libarary into Boost is more a focus than features/value-add. Will the above be considered in the future perhaps, as part of the candidate Boost.MPI library? Or will that be beyond the scope of the library? -- Dean Michael C.
