直通通信和拓扑结构研究

A Research of Cut-Through Communication and Topology

通过一开关系统把一并行处理系统中的各节点连接起来，在程序控制下，将欲通信的两节点间相应开关接通，实现两节点间信息的直接传输（直通通信）．各种常见宜通型拓扑结构对通信延迟、系统使用频带，加速比和效率的影响以及它们间的相互关系即为本文的研究内容．

Through a switch system, we can connect nodes of a parallel system. Under the control of programe,the switch system connects switches between two nodes that want to communicate, realizing cut-through communication between them. In this paper we investigate the influence of some general cut-through topological structures on communication delay, system communication bandwidth, speed-up ratio and efficiency.
