GPU Programming With OpenMP 5.0
Watch the youtube video available here. The video gives an introduction to GPU Programming using OpenMP 5.0.
Google Colaboratory provides free GPU access and is used as the programming platform in the video.
The video also points out few mistakes which first-time users may make. Please watch the video before the workshop day and get ready for the lab session.
