Motivation for this change

Since 2.3, NCCL 2 is released under BSD 3-Clause and can be built from source.

I have defined nccl_cudatoolkit_9_0, 9 (currently 9.2) and 10 because these are the builds available at (requires a free account). I have removed nccl_cudatoolkit_8, because although NCCL might be buildable with CUDA 8.0, cudatoolkit_8 is broken in Nixpkgs.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip" nix-review
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Assured whether relevant documentation is up to date
  • Fits
