摘要
高性能计算机网络对带宽的需求 ,使得如何提供高带宽的互连网络以及充分利用互连网络的固有带宽成为一个研究焦点 .基于 L inux操作系统 ,以千兆光互连接口卡为网络接口 ,设计实现了一种可用于机群系统的双环光互连网络 .介绍了光互连网络接口卡的基本结构 ,接口卡驱动软件的设计方法 ,双环光互连网络的拓朴结构及其特性 .分析测试了光互连网络的通信性能 ,指出了影响系统整体性能的关键因素 .
When making an ongoing transition to high performance computer neworks, it is found that the research focus is how to provide enough link bandwidth and how to take advantage of it well. A Linux-based twin-ring optical interconnection network is introduced, which can be used in computer cluster, including the design of optical interconnection interface card, the device driver, and the architecture. The communication performance has been tested and analyzed. The dominant factor in determining the overall performance is pointed out.
