Abstract: For parallel systems a Petri net based hierarchically decomposable integrated model, the PRM-net (Program Resource Mapping-net) model is developed. PRM-nets provide a modular concept for modelling parallel programs with a Petri net like graphical formalism called P-nets. Synthesis rules are given to model complex structures of processes by hierarchically folding process graphs. Modelling the pool of resources is also done by a Petri net like formalism: R-nets. Finally the assignment of the P-net (parallel program) to the R-net (resources) is modelled by arcs with origin in one net and sink in the other net. The modeling power of PRM-nets is illustrated in an example modelling the mapping of a neural network onto a distributed memory multiprocessor system.
