Abstract: "The IBM Scalable POWERparallel Systems 9076 SP2 connects RISC System/6000 POWER2 processors via the SP2 communication subsystem. This subsystem is based upon a low latency, high bandwidth switching network called the High-Performance Switch. The Switch incorporates a number of unusual features to scale aggregate bandwidth, enhance reliability, diagnose faults, and simplify cabling. It is a bidirectional multistage interconnect, and is a unified data and service network driven by a single oscillator. Switching elements contain a dynamically allocated shared buffer for storing blocked packet bytes from any input port. This paper examines the SP2 communication subsystem architecture and details its enhancements over the SP1, and overviews the subsystem support software."
