A few years ago I read that there were no drivers for GPU cards. I am sure the thing has changed for good. I am a scientist working with Fortran 200X and some C++ and I would like to learn how to code in parallel (CUDA is called the platform, though I am not sure it is the only one) in an Ubuntu laptop.
Are there GPU cards fully supported in Ubuntu? I mean, fully supported in a stable way, not some experimental stuff.
