Abstract

Clusters are now a dominant model for high-capacity, scalable computing based on a commodity cost structure. This paper describes the first generation PathScale™ InfiniPath™ adapter - a single chip ASIC directly connecting HyperTransport™ attached processors, such as the AMD Opteron™, to the InfiniBand™ network fabric. In addition to providing ultra-low communications latency, the PathScale InfiniPath adapter achieves high bandwidth from very small to large message sizes. Its performance also scales on multi-core processor nodes. Use of the InfiniBand switching fabric permits high bandwidth to be realized at a commodity fabric price point.
