A new model for the performance evaluation of synchronous circuit switched multistage interconnection networks

Patel (1981) proposed a probabilistic approach to analyze the performance of multiprocessor systems using synchronous multistage interconnection networks (MINs) based on a uniform reference model and the assumption of independent requests. Through extensive simulation, the authors have found that, in many cases, their model will result in rather significant inaccuracy. the factors which cause inaccuracy in Patel's model are investigated in detail. A new queueing model is then proposed and is shown to be very accurate. Since only six states are needed, this new model is very efficient computationally.<
