具有资源虚拟化的多租户云提供了资源的弹性，并消除了应用程序的初始集群设置成本和时间。然而，糟糕的网络性能、性能变化和噪声邻居是在公共云上执行高性能应用程序的一些挑战。在通信模式复杂的科学应用中利用这些虚拟化资源，需要低延迟的通信机制和丰富的通信构造集。为了最大限度地减少虚拟化开销，提出了一种新的HPC云低延迟网络方法，并在多技术软件定义网络上实现。针对高性能应用，对所提出的低延迟软件定义网络的效率进行了分析和评估。实验结果表明，最新的Mellanox FDR InfiniBand互连和Mellanox OpenStack插件为实现基于虚拟机的大消息大小高性能云提供了最佳性能。
Multi-tenant clouds with resource virtualization offer elasticity of resources and elimination of initial cluster setup cost and time for applications. However, poor network performance, performance variation and noisy neighbors are some of the challenges for execution of high performance applications on public clouds. Utilizing these virtualized resources for scientific applications, which have complex communication patterns, require low latency communication mechanisms and rich set of communication constructs. To minimize the virtualization overhead, a novel approach for low latency network for HPC Clouds is proposed and implemented over a multi-technology software defined network. The efficiency of the proposed low-latency Software Defined Networking is analyzed and evaluated for high performance applications. The results of the experiments show that the latest Mellanox FDR InfiniBand interconnect and Mellanox OpenStack plugin gives the best performance for implementing VM-based high performance clouds with large message sizes.
