Abstract

There are several research directions in Software Performance Engineering (SPE), covering the entire performance prediction process, but most of the tools developed so far implement only part of it or have restrictions. From a methodology perspective, current performance prediction tools rely either on analytical or simulation models, as separate techniques. This paper presents a performance analysis tool, Phymss (Performace Hybrid Model Solver and Simulator), which covers the analysis process from the input system model annotated with performance information to obtaining performance results and inserting them back into the original system model. Two analysis methods are implemented, for flexibility reasons: a multithreaded simulator and a hybrid solver that combines the analytical and simulation approaches in a new analysis technique, in order to investigate the benefits of such an approach.
