Performance analysis of parallel & embedded real-time systems based on measurement and visualization

This paper describes an approach to carry out performance analysis on systems which combine two major characteristics: real-time behaviour and parallel computational structure. It relies on a toolset composed of a monitoring system and a visualization tool. The steps to carry out performance analysis based on the toolset are clearly defined, and they are explained by means of a case study. First, the instrumentation process is described, and later, the performance views shown by the visualization tool are presented. It is suggested that these views are highly suitable for understanding the performance of parallel real-time systems.
