Visualization

Abstract

The authors explore the graphical representation of objects and processes as a means for understanding programs consisting of large numbers of concurrent processes. Their goal is to establish a technical foundation for research into the monitoring and debugging of large-scale concurrent programs. They explain declarative visualization and introduce some shared-data-space concepts and notation by means of a simple, nondeterministic, parallel algorithm. They discuss visual abstraction and their visualization methodology, which they illustrate by applying it to region labeling. Thy examine the relaxation of nonintervention that visualization makes possible.
