===== Abstract =====

{{ :io500:bofs:isc19:io500_isc19_full_1.jpg?400|}}

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/O** -- //Julian Kunkel//
  * **What's new with IO-500** -- //George 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 [[io-500-board@vi4io.org|steering board]].//
    * **Rationalizing Public Clouds HPC Performance** -- //Vinay Gaonkar//
    * **I/O performance variability in practice** -- //Glenn Lockwood//
  * **The new IO-500 list and analysis** -- //George Markomanolis, Julian Kunkel, Jay Lofstead, John Bent//
  * **Roadmap for IO-500** -- //Julian Kunkel//
  * **Discussion** and **Voice of the community** -- //Jay Lofstead// \\ We will prime a discussion with some observed issues and open the stage for feedback and issues.
