一个全互连可伸缩并行加速系统的体系结构设计

THE ARCHITECTURE OF A FULLY-CONNECTED SCALABLE PARALLEL ACCELERATOR

可伸缩（分布存储）多计算机系统（ｓｍＣ，ｓｃａｌａｂｌｅｍｕｌｔｉＣｏｍｐｕｔｅｒ）是目前并行处理系统研究的一个热点．它不仅有重要的学术价值．而且已被用户广泛地接受．本文介绍了一个计算引擎式的ｓｍＣ并行加速系统的体系结构设计．它的互连网络由支持Ｗｏｒｍｈｏｌｅ寻径技术和虚通道流控制的包寻径开关构成，实现了ＰＥ间逻辑上的全互连拓扑．该系统能够有效地在多用户、多任务状态下工作，具有良好的可伸缩性．

The fully-connected scalable parallel accelerator is a computing engine smC system,and this paper introduces its architecture.Its interconnection network is composed of the packet routing switches which support the wormhole routing and the virtual channel flow control.As a result,all of PEs in this system is fully-connected logically.This parallel accelerator can support multiuser and multitask efficiently,and can be scalable easily.
