Hi Brian,

You need to intiialize Boost.MPI not by creating a boost::mpi::environment object but by directly calling the C API function MPI_Init_thread. You will also need to be careful with threading, since you might get mismatches between probes and receives of messages if multiple threads handle the same message.
