Boost.MPI uses Boost.Serialization to transfer C++ class instances;
it handles the lower-level details of user-defined MPI datatypes for
you. So, you should just provide serialization support for all your
objects, and then you can just send/recv them directly.
I attach a very simple example, using a class to send the usual "hello
from rank XX" message.
