ISC'19

The IO-500 and the Virtual Institute of I/O

Date Tuesday, June 18th, 13:45-14:45
Venue Substanz (1, 2); Frankfurt, Germany

Abstract

The IO500 is quickly becoming the de facto benchmarking standard for HPC storage. Developed two years ago, the IO500 has released two official lists so far. A BoF highlight is the presentation of the fourth IO-500 list.

The general purpose of this BoF is to foster the IO500 and VI4IO communities to ensure forward progress towards the common goals of creating, sharing, and benefiting from a large corpus of shared storage data. We also serve as a repository of detailed information about production storage system architectures over time as a knowledge base for other researchers and system designers to use.

Goals of the BoF are to 1) reveal the current IO-500 list and provide highlights and insight; 2) advertise the community hub but also discuss and steer the direction of the community effort; 3) to discuss the benefit and direction of the efforts within the community.

The IO-500 benchmark consists of data and metadata benchmarks to identify performance boundaries for optimized and suboptimal applications. Together with comprehensive data from sites, supercomputers, and storage, in-depth analysis of system characteristics are tracked by the list and can be analyzed. In contrast to other lists, the IO-500 collects the execution scripts for providing means of result verification and sharing best practices for data centers.

Goals of the Virtual Institute for I/O are:

  • Provide a platform for I/O researchers and enthusiasts for exchanging information
  • Foster international collaboration in the field of high-performance I/O
  • Track, and encourage, the deployment of large storage systems by hosting information about high-performance storage systems

Expected HPC audience are 1) I/O experts from data centers and industry, 2) researchers/engineers working on high-performance I/O for data centers, 3) domain scientists and computer scientists interested in discussing I/O issues.

The outcome of this BoF will steer the direction of the community efforts.

Agenda

We have a series of interactive talks and discussions.

  • The Virtual Institute for I/OJulian Kunkel
  • What's new with IO-500George Markomanolis
  • Community lightning talks (5 minutes each)
    We invite everyone who has something interesting or critcal to submit a short abstract until June 11th to the steering board.
    • Rationalizing Public Clouds HPC PerformanceVinay Gaonkar
    • I/O performance variability in practiceGlenn Lockwood
  • The new IO-500 list and analysisGeorge Markomanolis, Julian Kunkel, Jay Lofstead, John Bent
  • Roadmap for IO-500Julian Kunkel
  • Discussion and Voice of the communityJay Lofstead
    We will prime a discussion with some observed issues and open the stage for feedback and issues.
