基于程控SP_2开关直通的计算机系统

Computer System Based on Programmable SP_2-Switch Cut-through Communication

在用SP2开关进行结点间互连的大规模并行处理系统中，引入可程控的结点间直通通信概念，相对于存储转发、虚拟旁通、蛀孔寻径和线路交换，系统性能均有进一步提高。文中对基于程控SP2开关直通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SP2开关直通是极具吸引力的结点间通信技术。

Massively parallel processing System using SP_2-Switch to interconnect among nodes & introducing programmable cut-through communication has better performance as compared with store-&forward, virtual cut -through, wormhole routing and circuit switching . Present6d in this paper is speed up ratio ,efficiency, latency & bandwidth of the programmable SP2-switch cut-through communication computer system. The result shows that the programmable SP2-Switch cut-throngh communication is very attactive communication technology among nodes for the massively parallel processing system.
