FollowGPUs for Science day 2022, October 25th
Introduction
NERSC is proud to reboot GPUs for Science Day. Perlmutter has played a crucial role in helping the wider scientific community leverage and embrace GPUs for their simulations. Our goal is to help facilitate the transition to GPU systems and to offer users the motivation, tools, and expertise they need to make this change possible. The day will start with an introduction to Perlmutter, followed by the current state of multiple compilers and supported programming models for running on GPUs. The majority of the agenda will showcase about ten science application teams to share their first-hand experiences and best practices on porting to GPUs. We hope this knowledge and lessons learned can be adapted to users’ own applications. The day will end with a panel on popularly used performance portable accelerator programming models.
With the announcement of Cori’s approaching retirement in January 2023, users migrating their applications from Cori to Perlmutter GPUs are highly encouraged to join. This event is also open to OLCF and ALCF users.
Date and Time: 8:30 a.m. - 5 p.m. (Pacific Daylight Time, UTC-7), October 25 (Tuesday)
