My impression is that 18.04 is required for Vanity Search.
I don't kwon, I'm using ubuntu 18.04.2 LTS with an old quadro and it is working well except that I had to repatch again the cuda driver in order to make it work (quite a nightmare) following a kernel update. Kernel maintainers has again beautified the code breaking the backward compatibility by removing and changing some kernel functions. pfff....
So do you think that the standard 18.04 distro will work for GPU? Or would I need to install some specific CUDA software for 18.04?
I know it works for CPU (as long as you install g++).
