基于InfiniBand的高性能计算机技术研究

网络性能一直是制约高性能计算技术发展的瓶颈，无论是面向计算的网络还是面向存储的网络，通信速度的发展远落后于CPU的发展．InfiniBand互连结构能够缩短网络和CPU之间的性能差距，使高性能计算机的性能趋于平衡．2000年在InfiniBand协议发展初期，国家并行计算机工程技术研究中心就在国家“八六三”计划的支持下开始对InfiniBand协议展开了深入研究，旨在改进高性能计算特别是集群系统的互连性能，研制出符合InfiniBand标准规范的高性能互连部件，并最终开发出了具有自主知识产权的InfiniBand互连网络产品．论述了以自行研制的InfiniBand部件技术为基础的高性能集群计算机系统的组成、结构和应用，并对系统性能进行了实验分析．

Research on High Performance Computer Technology Based on InfiniBand

The network performance is the key bottleneck which always restricts the development of high performance computing technology, whether computing network or storage network, the progress of communication is lag behind that of CPU. InfiniBand interconnection architecture can fill the performance gap in network and CPU, and make the performance of high performance computing to balance in computing and communication. For developing high performance interconnection components of HPC, the research on InfiniBand specification began in 2000, and the InfiniBand network products branded with "SunWay" were worked out in 2003. Discussed in this paper are the components, archtecture and applications of the high performance computing system based on the InfiniBand technology, and then the result of performance test is shown.
