Unfortunately, there are no references to non-blocking MPI calls in the OcamlMPI source. However, I noticed that MPI_Send is used for blocking versions. Under certain conditions, MPI_Send will behave like a non-blocking call (for example, for small messages that are suitable for outgoing message buffers by default), but this behavior is implementation dependent and cannot be relied on.
