The IO500 is quickly becoming the de facto benchmarking standard for HPC storage. The IO500 has released official lists bi-annually at ISC and SC events since SC17 and is constituted by over 100 submissions in the full list. Moreover, the IO500 was used at SC Student cluster competition since SC19 and illustrates the increased need for more efficient storage. A BoF highlight is the presentation of the new IO500 list.

The purpose 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 1) reveal the latest IO500 list and provide highlights and insight; 2) advertise the community hub but also discuss and steer the direction of the community effort and latest developments 3) to discuss the benefit and direction of the efforts within the community.

The IO500 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 IO500 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:

  • I/O experts from data centers and industry
  • Researchers/engineers working on high-performance I/O for data centers
  • Domain scientists and computer scientists interested in discussing I/O issues.

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