Your question is somewhat outside the scope of this list. Perhaps people may chime in with some suggestions, but that's more of a threading question than an MPI question.
Be warned that you need to call MPI_Init_thread (not MPI_Init) with MPI_THREAD_MULTIPLE in order to get true multi-threaded support in Open MPI. And we only support that on the TCP and shared memory transports if you built Open MPI with threading support enabled.
