A user of a non-CUDA-aware MPI library could implement a more efficient pipeline using CUDA streams and asynchronous memory copies to speed up the communication. Even so, a CUDA-aware MPI can more efficiently exploit the underlying protocol and can automatically utilize the GPUDirect acceleration technologies.
