IPoIB在国产并行系统上的实现与优化

IPoIB是一种在InfiniBand网络上支持IP的协议，使IP应用程序可以运行在InfiniBand网络上.我们在国产并行系统上实现了IPoIB，通过乱序处理、内存拷贝优化、网络参数调优和避免应答延迟的优化手段，实现了IPoIB在国产并行系统上的性能提升.实验结果表明，IPoIB在国产并行系统上正确运行，网络带宽与优化前相比提高近6倍，与10GbE万兆以太网相比，IPoIB更具优势，乱序处理机制减少乱序效果明显.     

IPoIB体系结构及其应用

InfiniRand (IB) is a high speed, channel based interconnecting technology between systems and devices. It will remove the bottleneck limiting the performance of current servers and storage divices. This article proposes an IP over IrdiniBand (IPoIB) architecture and its application. It will function as a bridge between IP and IB architecture insystems IP and IB coexists. It enables the applications to take advantages of IB without changes in upper layers IP and other protocols. We also introduce the IPoIB protocol and show some experiment results in this paper. The experi-ment results show that IPoIB is suitable to be used in the front-end servers and interface devices for the IrdiniBand-based network servers.     

InfiniBand服务器接口机协议转换的设计与分析

随着Interact数据中心的快速发展，正在采用的InfiniBand体系结构的网络服务器将成为机群服务器的主流。本文以Infiniband协议为由得出协议转换是最佳方案，然后介绍了IB与IP协议转换的基本原理，最后提出了一种嵌入式接口机的协议转换方案，并用实验证实了它是优于IPoIB的解决方案。
