>I am not very familiar with GPU programming but the small amount I've tried was nothing but pain a few years ago on linux, it was so bad that Torvald publicly used the f word in a very public event.
I'm pretty sure Torvalds was giving the finger over the subject of GPU drivers (which run on the CPU), not programming on the Nvidia GPU itself. Particularly, they namedropped Bumblebee (and maybe Optimus?) which was more about power-management and making Nvidia cooperate with a non-Nvidia integrated GPU than it was about the Nvidia GPU itself.
