SUMMARY:InfiniBand, Omni-Path, and High-Speed Ethernet for Beginners
DESCRIPTION:Dhabaleswar Panda, Hari Subramoni, and Sourav Chakraborty (Ohi
 o State University)\n\nInfiniBand (IB), Omni-Path, and High-Speed Ethernet
  (HSE) technologies are generating a lot of excitement toward building nex
 t generation High-End Computing (HEC) systems including clusters, datacent
 ers, file systems, storage, cloud computing, and Big Data (Hadoop, Spark, 
 HBase, and Memcached) environments. RDMA over Converged Enhanced Ethernet 
 (RoCE) technology is also being widely deployed. This tutorial will provid
 e an overview of these emerging technologies, their offered architectural 
 features, their current market standing, and their suitability for designi
 ng HEC systems. It will start with a brief overview of IB, Omni-Path, and 
 HSE. An in-depth overview of the architectural features of IB, Omni-Path, 
 and HSE (including iWARP and RoCE), their similarities and differences, an
 d the associated protocols will be presented. Next, an overview of the Ope
 nFabrics stack which encapsulates IB, HSE, and RoCE (v1/v2) in a unified m
 anner will be presented. An overview of the Libfabrics stack will also be 
 provided. Hardware/software solutions and the market trends behind IB, Omn
 i-Path, HSE, and RoCE will be highlighted. Finally, sample performance num
 bers of these technologies and protocols for different environments will b
 e presented.\n\nTag: Introductory, Networks\n\nRegistration Category: Tuto
