ISC'20

Impact of COVID-19: The release of the list will take place regardless of ISC canceling BoF sessions.

This is the periodic ISC'20 list release but earlier than the ISC-HPC conference when we typically release the list to prevent conflict with their digital program.

The event will be held using BlackBoard, which is a browser-based solution. Please register via the Google Form, we will then provide connection details 48-hours before the event.

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 the 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.

We will have a series of interactive talks and discussions. Details will be announced soon.
