Intel® Xeon Phi™ Coprocessor and Intel® True Scale FabricWhile the overall compute power in a single node is important, to further scale performance these nodes must be interconnected by a highly efficient network infrastructure. This paper will lay out the Intel® Xeon Phi™ coprocessor HW and SW environment and compare performance data on the Verbs and Offload InfiniBand* architecture to the Intel® True Scale Fabric with using the PSM/on-load architecture. To obtain best utilization from the a server utilizing the Intel® Xeon® processor and the Intel® Xeon Phi™ coprocessor, the Intel® coprocessor communications link (CCL) SW technology is required. There are two versions; an early version was released that supports the verbs/offload architecture. A succeeding release has been optimized for the Intel® True Scale Architecture PSM/on-load-based HCA. This Intel True Scale Architecture HPC networking infrastructure enables a clustered application to approach its maximum possible efficiency.Read the full Intel® Xeon Phi™ Coprocessor and Intel® True Scale Fabric Overview.
