QSNET/sup II/ optimizes interprocessor communication in systems built from standard server building blocks. Its short-message processing unit permits fast injection of small messages, providing ultra-low latency and scalability to thousands of nodes. Thus, in a sense, the high-performance network in a cluster computer is the computer because it largely defines achievable performance, widening the range of the applications a cluster can efficiently execute, as well as defining its scalability, fault tolerance, system software, and overall usability.
