I got the m queens GPU app to run to my Radeon VII. I had to upgrade the driver to 20.12.1. Not sure what the min version to work is. 8GB app avgs about 5-6 minutes
Since the requirement is 8gb, and the VII has 16gb, I decided to try running two at a time. Seems to work just fine, and the run times are no longer. Sweet!
