The objective of this research is to develop timed Petri net models of a wide range of multiprocessor architectures, and in particular, multithreaded multiprocessors. Although many examples refer to a 16-processor system connected by a two-dimensional torus-like network, as shown in Fig.1, they might as well refer to a 16-processor system with a hypercube-type connecting network, as shown in Fig.2, or other types of interconnections. The concept of performance equivalence explains the performance similarities between such two systems, as well as between many others, for example, a 64-processor system connected by a three-dimensional torus-like network and a 64-processor system connected by a hypercube network.
