Abstract

This is a review report about the high performance switch and the programming interfaces on IBM SP2 . Based on a collection of materials from many other sources and our experience using SP2, we summarize internals of HPS configuration and its supporting software, transport protocols, message passing libraries, programming interfaces and software layers. Performance data of the HPS are also collected and given in this report to help us develop strategies of benchmarking the SP2 communication subsystems.
