Hi Omar, with serialization of C++ objects is fundamentally no different than sending structs with the C bindings. See [1] for an example of how to use MPI_Isend/MPI_Irecv. Be advised though that MPI won't guarantee that the communication will always run concurrently.
If your objects contain pointers or containers like std::vector, std::map, and friends, then you might want to take a look at boost::mpi [2] whose serialization can handle even tricky cases, but which (boost::serialize) is also much slower than native MPI.
