Abstract
Many analytical models of wormhole-routed networks have been proposed over the past few years. Most of these models, however, have been developed for unicast (or point-to-point) traffic. There has been comparatively little activity in the area of analytical models of collective communication, such as broadcast. As a result, most existing studies have relied on simulation to evaluate the effect of collective communication algorithms on the network traffic. This paper presents a new analytical model for predicting message latency in the hypercube in the presence of broadcast communication. Results obtained through simulation experiments show that the model exhibits a good degree of accuracy in predicting message latency under different working conditions.
