Poster Abstract: The OMPCM Simulator for Model-Based Software Performance Prediction

Software performance models play an important role in early stage quality evaluations. Performance models in particular allow for comparing architectural alternatives before unfavourable design decisions are made that need to be revised in a costly procedure. The Palladio component model (PCM) is a modelling language for component-based software architectures. Instances of the PCM can already be analysed for their performance using analytical or simulative approaches. It is, however, difficult to obtain accurate performance predictions for network-intensive distributed systems. This is mainly due to the simplistic network model used so far. In this paper, we present the OMPCM simulator, which integrates OMNeT++ network simulation with architecture-level software performance prediction. OMPCM models can be automatically created from PCM models using a chain of model transformations.
