Performance evaluation of parallel programs in parallel and distributed systems

Abstract

This paper deals with performance evaluation of parallel and distributed systems based on monitoring of concurrent interdependent activities. First a model is introduced for describing the dynamic behavior of computer systems in terms of events. Then, a distributed hardware/hybrid monitor system based on event driven monitoring and its tool environment SIMPLE are presented. We emphasize the tool environment as a prerequisite for successful performance evaluation. The tool environment for evaluating event traces, which integrates the data access interface TDL/POET and a set of evaluation tools for processing the data, makes evaluation independent of the monitor device(s) and the object system. It provides a problem oriented way of accessing event traces.
