SP1 high-performance switch
Abstract
The IBM Scalable POWERparallel Systems1 9076 SP11 connects RISC System/60001 processors via a communication network called the High-Performance Switch. This Switch - based upon the Vulcan parallel processor - incorporates a number of unusual features to enhance reliability, diagnose faults, and simplify cabling. This paper examines the SP1 Switch architecture and implementation and overviews the Switch support software.
