This paper describes a multiview characterization of concurrent software and systems suitable for displaying and analyzing performance information. The views draw from well-known descriptions, and are compatible with established techniques and tools such as execution graphs, Petri Nets, StateCharts, structured design or object-oriented design, and various models for performance. The views are connected by means of a “Core model” and are used together to extract information relating to system integration, such as interprocess overheads, and the delay behavior of separate software components in complex systems. The integration of the views in the Core assists by converting results in one view (such as scheduling delay for resources) to parameters in another (such as delays along a path). The ultimate goal of the views is to support designers in making tradeoffs which involve performance, and to provide early assessment of the performance potential of software designs.
