Performance analysis of complex systems by integration of dataflow graphs and compositional performance analysis

In this paper we integrate two established approaches to formal multiprocessor performance analysis, namely Synchro-nous Dataflow Graphs and Compositional Performance Analy-sis. Both make different trade-offs between precision and ap-plicability. We show how the strengths of both can be combined to achieve a very precise and adaptive model. We couple these models of completely different paradigms by relying on load descriptions of event streams. The results show a superior per-formance analysis quality.
