SUMMARY:Networking Technologies for High-Performance Computing: Principles
  and Solutions
DESCRIPTION:Dhabaleswar Panda, Hari Subramoni, Bharath Ramesh, and Kaushik
  Kandadi Suresh (Ohio State University)\n\nInfiniBand (IB), High-speed Eth
 ernet (HSE), RoCE, Omni-Path, EFA, Tofu, and Slingshot technologies are ge
 nerating a lot of excitement towards building next generation High-End Com
 puting (HEC) systems including clusters, datacenters, filesystems, storage
 , cloud computing, Big Data (Spark) and AI (Deep Learning and Machine Lear
 ning) environments. This tutorial will provide an overview of these emergi
 ng technologies, their offered architectural features, their current marke
 t standing, and their suitability for designing HEC systems. It will start
  with a brief overview of IB, HSE, RoCE, Omni-Path, EFA, Tofu, and Slingsh
 ot. In-depth overview of the architectural features of IB, HSE (including 
 iWARP and RoCE), and Omni-Path, their similarities and differences, and th
 e associated protocols will be presented. An overview of the emerging NVLi
 nk2, NVSwitch, AMD Infinity Fabric, Slingshot, and Tofu architectures will
  also be given. Next, an overview of the OpenFabrics stack and Libfabrics 
 software stack to support a range of different interconnects will be provi
 ded. Hardware/software solutions and the market trends behind these networ
 king technologies will be highlighted. Sample performance numbers of these
  technologies and protocols for different environments will be presented. 
 Finally, hands-on exercises will be carried out for the attendees to gain 
 first-hand experience of running experiments with high-performance network
 s.\n\nTag: Architecture and Networks, Distributed Computing\n\nRegistratio
