中文摘要: 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.
中文关键词: IPoIB  网络优化  网络参数  内存拷贝  带宽
Abstract:IPoIB is a protocol that supports traditional Ethernet over InfiniBand networks, allowing IP applications to run on InfiniBand networks. We realize IPoIB on the domestic parallel system to improve the performance of IPoIB on the system, we also propose four optimization methods, namely, reordering packets, optimizing memory copy, tuning network parameters, and avoiding delayed acknowledgement. Practice shows IPoIB runs correctly on the domestic parallel system, and under the methods of optimum, IPoIB's network bandwidth performance is nearly 6x higher than the not-tuned version. IPoIB has more advantages compared with 10 GbE, and the reordering method shows obvious effects.
