We currently (appear to) support CUDA versions 7.5 through 11.2, and SM 3.5
through 8.0. (All CUDA versions are not compatible with all SM's, but
allowed combinations are set by NVIDIA, not by us.)
The argument for SM3 is that there are still K80's out there, although I
think this must be less and less true. There certainly are GTX 980's still
in use, and supporting SM5 would make sense if it doesn't cost anything.
But I'm fine with dropping support for SM5 if it helps us with code
development or maintenance. (If a future user really needs to run on older
cards, they can stick with Amber20.)
The CUDA experts should make the decisions here, not me.
