Abstract

The objectives in workload characterization for parallel systems are to provide adequate representations of the programs and the associated data and to characterize the way in which these programs are submitted to the system (user interaction). In this work a systematic framework and a corresponding methodology for workload modeling of parallel systems is proposed. The corresponding methodology specifies the steps for constructing a workload model within this framework. To illustrate the contribution of this approach, the framework is used as a workload model classification scheme and the methodology is applied in a case study. 1 Introduction Modeling, i.e. selecting and characterizing, the workload of a parallel system is an important task in every performance evaluation study, as all the estimated or observed performance results will depend on the load, that the system under test has to process. While workload modeling for uniprocessor systems is a well established discipline, only...
