SIMPLE: A Performance Evaluation Tool Environment for Parallel and Distributed Systems

This paper describes SIMPLE: a performance evaluation tool environment for parallel and distributed systems based on monitoring of concurrent interdependent activities. We emphasize the tool environment as a prerequisite for successful performance evaluation. All tools use the data access interface TDL/POET which can decode measured data of arbitrary structure, format and representation. This makes the evaluation independent of the monitor device(s) used and the system monitored. It also provides a problem-oriented way of accessing the data. Therefore it is very easy to adapt SIMPLE to any kind of measured data and to understand the evaluation results.
