Abstract

We explore optical switching to extend network programmability to the physical layer and discuss applications of a Layer-1 software-defined network (SDN) in AI/HPC clusters. In this context we identify two applications for optical circuit switches (OCSs): failure resilience and reconfigurable topologies for deep learning workloads. We present experimental results from a DGX-based testbed towards improving failure resilience and a simulation analysis for efficient deep learning training in AI clusters.

用于数据中心和先进计算系统的光交换[特邀]

我们探索光交换将网络可编程性扩展到物理层，并讨论了第一层软件定义网络（SDN）在AI/HPC集群中的应用。在这种情况下，我们确定了光电路开关（ocs）的两种应用：故障恢复能力和深度学习工作负载的可重构拓扑。我们展示了基于dgx的测试平台的实验结果，旨在提高故障恢复能力，并对人工智能集群中有效的深度学习训练进行了模拟分析。

期刊介绍： The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
