TimeSunday, June 24th9am - 1pm
DescriptionInfiniBand (IB), Omni-Path, and High-speed Ethernet (HSE) technologies are
generating a lot of excitement towards 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.
RDMA over Converged Enhanced Ethernet (RoCE) technology is also emerging. 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, 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, and the
associated protocols will be presented. Next, an overview of the OpenFabrics
stack which encapsulates IB, HSE, and RoCE (v1/v2) in a unified manner will be
presented. An overview of the libfabrics stack will also be provided.
Hardware/software solutions and the market trends behind IB, Omni-Path, HSE, and
RoCE will be highlighted. Finally, sample performance numbers of these
technologies and protocols for different environments will be presented.
Content Level The content level will be as follows: 60% beginner, 30% intermediate, and 10% advanced.
Target Audience This tutorial is targeted for various categories of people (newcomers, users, researcher, managers, and administrators) working in the areas of high-performance communication and I/O, storage, networking, middleware, virtualization, cloud computing, deep learning, Big Data and applications related to high-end systems.
PrerequisitesThere is no fixed pre-requisite. As long as the attendee has a general knowledge of high-performance computing, networking, storage, and related issues, he/she will be able to understand and appreciate it. The tutorial is designed in such a way that an attendee gets exposed to the topics in a smooth and progressive manner.
