GPU Tutorial Series

Apr. 6, 2021

9:00 am – 5:00 pm MDT

Boulder, Colorado

The GPU Tutorial Series will be held virtually April 6th, 13th and 20th, 2021 by the National Center for Atmospheric Research (Boulder, Colorado, USA).



These three hands-on tutorial sessions will begin with a short introduction to GPU architecture, terminology, and concepts.  Participants will be guided through basic examples of how to port code using OpenACC directives on a single GPU. The second session will introduce the CUDA programming model along with additional coding practice on single GPUs. We will also be covering troubleshooting tips for commonly seen build and run errors, along with guidance on how to perform basic profiling. The third session is dedicated to programming Multi-node Multi-GPU with OpenACC. All three sessions will have presentations and coding practice sessions.
