With respect to the CUDA-aware support, Ralph is correct. The ability to send and receive GPU buffers is in the Open MPI 1.7 series. And incremental improvements will be added to the Open MPI 1.7 series. CUDA 5.0 is supported.

That is, running MPI code on the Phi cards or across the multicore and Phi, as Intel MPI does? thanks...

The CUDA code is not in the 1.6 series as it was developed after that series went "stable". It is in the 1.7 series, although the level of support will likely be incrementally increasing as that "feature" series continues to evolve.
