Abstract:   IBM Power 775 (P7IH) is the latest supercomputing system that was designed for high-productivity and high-performance. The key
innovation on the hub-chip based network makes it perform superior for traditional HPCC benchmarks. In this paper, we detailed characterize the bared network performance with a thin communication stack. Based on that, we present a systematical performance analysis of the data-intensive benchmark, Graph500's Breadth First Search on P7IH. We then provide insight
into the overall interaction between hardware and software and present the lesson learned on the key bottlenecks of both
architecture and data-intensive application.
