A PERFORMANCE-MODEL OF PIPELINED K-ARY N-CUBES

Pipelined communication using virtual channels can realize low latency , high throughput, inter-processor communication. This paper presents an analytic performance model of pipelined communication in k-ary n-cu bes. The model contains elements intended to capture and study key per formance issues. In addition to the modeling of throughput and latency , the following issues are addressed using this model: 1) the tradeoff between full-duplex vs. half-duplex links, 2) the effects of intranod e delay, 3) the effects of buffer size for each virtual channel, Detai led simulation experiments under a variety of conditions establish the viability of this model.
