Abstract :
An analytical model for the performance evaluation of asynchronous hypercubes is presented. This analysis is aimed at modeling a deadlock-free wormhole routing scheme prevalent on second-generation hypercube systems. Probability of blocking and average message delay are discussed. The communication traffic to find the probability of blocking is the starting point. The traffic analysis can capture any message destination distribution. The average message delay that consists of two parts is found. The analysis is extended to virtual cut-through routing and random wormhole routing techniques. The validity of the model is demonstrated
