Parallel roadmaps: discrete to continuous

Parallel Roadmaps are apparently naive visual constructs, which remain intelligible and provide invaluable debugging clues as program complexity increases. With a few activities, roadmaps are discrete and detailed. With large numbers of them, continuous regions are formed by coalescing of adjacent activities. The main thesis of this paper is that a smooth transition from discrete to continuous maps, without changing the basic graphical entities, is an effective means to deal with parallelism at largely different scales
