Last June (2013), Mellanox released a white paper (link) where the GPI-2 support for heterogeneous architectures, namely Intel’s Xeon Phi, is highlighted:
“Over the last decade, specialized heterogeneous hardware designs ranging from Cell over GPGPU to Intel Xeon Phi have become a viable option in High Performance Computing mostly due to the fact that these heterogeneous architectures allow for a better flops-per-watt ratio than conventional multi-core designs. The upcoming new GASPI standard will able to bridge this gap in the sense that GASPI can provide partitioned global address spaces (so called segments), which span across both the memory of the Host and e.g. an Intel Xeon Phi.”
