Abstract


We show in this paper how to evaluate the performance of pipeline-structured parallel programs with skeletons and process algebra. Since many applications follow some commonly used algorithmic skeletons, we identify such skeletons and model them with process algebra in order to get relevant information about the performance of the application, and to be able to take good scheduling decisions. This concept is illustrated through the case study of the pipeline skeleton, and a tool which generates automatically a set of models and solves them is presented. Some numerical results are provided, proving the efficacy of this approach.
