By the way, have you considered how your library might be used to propagate C++ exceptions thrown on one or more processors to the other processors? Robust parallel termination semantics are difficult to achieve and the ability to propagate C++ exceptions in parallel can greatly improve program behavior. Your library seems like a natural place to provide this capability.
I've mused that such a thing might be possible, but I've never considered how it should be done or where it would fit into the library.
We've done some work in this area if you're interested.
Yes, I'd like to learn more about this. I don't expect we'd be able to support this feature in the initial version of the library (just covering MPI 1.1 requires quite a bit of effort, and we've had requests for MPI 2.0 features as well), but I think the (candidate) Boost.MPI would benefit from the ability to propagate C++ exceptions across processors.
