Portable networking, including sockets, timers, hostname resolution and socket iostreams.
So it appears you could implement MPI on top of ASIO. My bad.
I don't know MPI but indeed Boost.Asio is extensible: You can create services and add them to the core I/O service object in Boost.Asio. There is not really a step-by-step tutorial how to do this but with some trial and error and looking at existing source code (in Boost.Asio and examples) it works. In fact it would be nice if these services are collected somewhere (but then again I don't kow if there are so many services developed anyway).
I'ld rather like to see Asio implemented on top of MPI.
How would that be? It seems that Asio is more low-level and generic and MPI, so implementing Asio on top of MPI is not possible. - Volodya
