Computer System Based on Programmable Crossbar Switches Cutthrough Communication

在用纵横交换开关进行节点间互连的大规模并行处理系统中，引入可程控的节点间直通通信概念，相对于存储转发、虚拟直通、蛀孔寻径和电路交换，系统性能均有进一步提高。文中对基于程控纵横交换开关直通信息交换技术的计算机系统之加速比、效率、延迟时间和使用频带等系统性能参数进行了研究。结果表明，在大规模并行处理系统中，程控纵横交换开关直通是更具吸引力的节点间通信技术。

Massively parallel processing system using crossbar switches to interconnect nodes & introducing programmable cutthrough communication between nodes has better performance as compared with store&forward,virtual cutthrough,wormhole routing and circuit switching.Presented in this paper are speed^up ratio,efficiency,delay & bandwidth of the computer system based on the programmable crossbar switches cutthrough communication.The result shows that the communication is an attractive communication technology for nodes of the massively parallel processing system.
