OCCAM prototyping of massively parallel applications from colored Petri-nets

The authors present a technique to build a massively parallel application from a formal description. They use the colored Petri-net formalism to model applications. This formalism allows them to concisely describe parallel applications. Theoretical results on this formalism contribute to proving the correctness of the description before implementation. Furthermore, they use some linear invariants to decompose the model into interacting state machines which are easy to implement. An important feature introduced consists in using color to map state machines and to distribute data and communication onto a formal architecture description.<>
