InfiniBand是用于商品HPC集群的事实上的网络技术，并且已经被广泛部署。然而，大多数生产大规模InfiniBand群集使用简单的路由方案（如目的地mod-k路由）来路由流量，这可能导致通信性能下降。在这项工作中，我们调查使用OpenFlow风格的软件定义网络（SDN）技术，以克服路由的不足，在InfiniBand。我们设计了一个增强的InfiniBand与OpenFlow风格的SDN功能，并演示了一个用例，说明了如何在HPC集群中利用SDN功能，以提高系统和应用程序的性能。最后，我们通过模拟生产HPC集群的作业跟踪，量化了具有OpenFlow风格SDN功能的InfiniBand在平衡网络负载方面的潜在优势。结果表明，具有SDN功能的InfiniBand可以实现比传统的InfiniBand更好的网络负载平衡HPC集群。
InfiniBand is the de facto networking technology for commodity HPC clusters and has been widely deployed. However, most production large-scale InfiniBand clusters use simple routing schemes such as the destination-mod-k routing to route traffic, which may result in degraded communication performance. In this work, we investigate using the OpenFlow-style Software-Defined Networking (SDN) technology to overcome the routing deficiency in InfiniBand. We design an enhanced InfiniBand with OpenFlow-style SDN capability and demonstrate a use case that illustrates how the SDN capability can be exploited in HPC clusters to improve the system and application performance. Finally, we quantify the potential benefits of InfiniBand with OpenFlow-style SDN capability in balancing the network load by simulating job traces from production HPC clusters. The results indicate that InfiniBand with SDN capability can achieve much better network load balancing than traditional InfiniBand for HPC clusters.
