I have written up a blog post here[1] which describes my experience with trying to use OpenCL on Guix. While researching this, I found a few messages in IRC and on guix-help wondering how to get this to work, so I hope this helps someone.
As always, thanks to everyone involved in Guix. [1] https://katherine.cox-buday.com/blog/2021/07/05/trying-opencl-on-guix-an-experience-report/ -- Katherine
