Session Formats
TimeSunday, 13 November 20228:30am - 5pm CST
DescriptionThe aim of this workshop is to bring together developers and researchers with an interest in practical solutions, technologies, tools and methodologies that enable the development of performance-portable applications across a diverse set of current and future high‑performance computers.

We draw from a broad research audience that includes standard languages and runtimes, algorithmic techniques, tools, libraries and non‑standard techniques such as domain-specific languages. We also expect to see submissions from application teams documenting their experiences, good and bad, and those developing metrics and measurement techniques for performance portability and productivity.

This workshop has a proven track record of playing a shepherding role for the broader community in identifying and adapting to technology trends while fostering increased transparency and rigor for performance, portability and productivity. The importance of this role will only increase with the growing diversity and scope of hardware and software platforms, including more-complex workflows and data center scale.
