Neat project!

Some quotes from the conclusion:

"Nixpkgs CUDA aarch64 ecosystem is quite healthy"

Thanks to nix-community's 80 core ampere system

"Flakes make a good user interface"

This one is for you SomeoneSerge (matrix works sometimes)

"Lack of cached aarch64 CUDA builds"

👀💸

"Uneven freshness of packages"

Until we unlock core and maintainer cloning, that's going to be tough to change (especially reagrding how fast the whole space is moving).

"Community lacks GPU hardware"

Yes. And CPU too 😅

I find it really cool that someone wrote a convenient flake to make the DGX spark work OOTB.

@neobrain:matrix.orgneobrainIt's working really nicely on mine too, but the lack of cache definitely hurts 😭07:07:44
