Introduction to Networking Technologies for High-Performance Computing
DescriptionInfiniBand (IB), High-speed Ethernet (HSE), RoCE, Omni-Path, EFA, Tofu, Slingshot, and Aquila technologies are generating a lot of excitement toward building next-generation High-End Computing (HEC) systems including clusters, datacenters, file systems, storage, cloud computing, and Big Data (Hadoop, Spark, HBase, and Memcached) environments. This tutorial will provide an overview of these emerging technologies, their offered architectural features, their current market standing, and their suitability for designing HEC systems. It will start with a brief overview of IB, HSE, RoCE, Omni-Path, EFA, Tofu, Slingshot, and Aquila. An in-depth overview of the architectural features of IB, HSE (including iWARP and RoCE), and Omni-Path, their similarities and differences, and the associated protocols will be presented. An overview of the emerging NVLink/NVLink2/NVSwitch, Slingshot, Tofu, and Aquila architectures will be given. An overview of OpenFabrics stack which encapsulates IB, HSE, and RoCE (v1/v2) in a unified manner will be presented. An overview of libfabrics and UCX stacks will also be provided. Hardware/software solutions and the market trends behind these networking technologies will be highlighted. Sample performance numbers of these technologies and protocols will be presented. Finally, hands-on exercises will be carried out for the attendees to gain first-hand experience in running experiments with high-performance networks.
