摘　　要：随着对高性能计算机性能需求的不断提升,高性能计算机的系统规模在逐渐扩大,系统内的互连网络已经成为影响性能的关键因素。如何基于高阶路由器构建更大规模、更低网络延迟以及成本、更高网络吞吐率的互连网络,是目前的主要研究方向。针对目前广泛应用的高阶网络进行特性分析,并对其中的环网以及树网进行综合,提出了一种新型层次化混合互连网络拓扑结构。该结构具有良好的可扩展性以及通信能力,并在网络模拟器NetSim上对其性能进行了仿真和分析。With the continuous expansion of high performance computer systems to meet the increas-ing requirements for high performance computers,the interconnectiction network system has become the key factor that influences the performance. How to design larger-scale networks faster with lower laten-cy and lower cost,and larger throughput based on high-radix router by making full use of thigh-radix router is currently the main research direction. We analyze the features of the work and synthesize the torus and fat-tree topology,and put forward a new hierarchical hybrid intercon-nection network topology. The proposed topology has satisfactory scalability and communication capa-bility. W finally use the network simulator NetSim to simulate and analyze it performance.
