===== Abstract =====

{{ :io500:bofs:sc18:sc-bof-ceremony-10.jpeg?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 third 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 short talks followed by a discussion.
