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 cubes. The model contains elements intended to capture and study key performance 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 intranode delay, (3) the effects of buffer size for each virtual channel. Detailed simulation experiments under a variety of conditions establish the viability of this model
