 ruro | Also, I occasionally have some free time and I would like to spend it on improving the state of CUDA in nixpkgs/NixOS. Do you have any suggestions for which issues I should start with? Alternatively, I could just start going down the list of eval/build failures on the nix-community CUDA builder... | 16:24:29 |

I am not a complete newbie, but I haven't contributed to nixpkgs all that much (above PR is my third). I guess, I could just start going down the list of eval/build failures on the nix-community CUDA builder... but that might end up just being treadmill work. | 16:28:22 |

Looks like we need to wait for https://github.com/NixOS/nixpkgs/pull/306172 I meant to close that since I’ll make a new PR for the CUDA-packages work | 16:47:34 |
 Gaétan Lepage | Ok Connor. Do we have a short-term alternative to get this library ? | 16:48:28 |
| connor (burnt/out) (UTC-8) | Depends on what you mean by short term :( | 16:53:34 |
| connor (burnt/out) (UTC-8) | I should have everything landed by 25.05 but I suppose we’ll need it prior to that | 16:54:03 |
| connor (burnt/out) (UTC-8) | I guess I can start trying to land things, but it’ll cause some breakages and I don’t have docs written yet | 16:54:43 |
| Gaétan Lepage | I'm asking for pytorch (https://github.com/NixOS/nixpkgs/pull/377785). There is no emergency and we can surely wait before updating it. | 16:56:39 |
| connor (burnt/out) (UTC-8) | Ugh didn’t they also remove support for CUDA 12.1 | 16:58:19 |
| connor (burnt/out) (UTC-8) | Also I think they support newer architectures now (maybe Blackwell?) | 16:58:36 |

Ugh didn’t they also remove support for CUDA 12.1 From the CI at least: https://github.com/pytorch/pytorch/pull/141271, https://github.com/pytorch/pytorch/pull/142177 | 16:59:51 |
| connor (burnt/out) (UTC-8) | My bad I mixed up the CI removal and https://github.com/NVIDIA/TensorRT-Model-Optimizer/releases/tag/0.23.0 removing support for CUDA 11 | 17:02:04 |

Which package provides libcusparseLt.so.0 ? It's separate https://developer.download.nvidia.com/compute/cusparselt/redist/ | 02:13:02 |
| connor (burnt/out) (UTC-8) | I am so tired
But now have setup hooks which can catch common issues like the order of different CUDA directories in a run path
Or fail a build if NVCC’s host compiler leaks out (which can/will cause glibc/glibcxx symbol issues)
Even beyond that
I implemented utility functions for arrays and associative arrays in bash because I got tired of repeating myself in different hooks
And then when I got tired of repeating myself in tests for those functions and hooks, I made a utility derivation to make testing for expected arrays and associative arrays easier | 06:55:57 |
| connor (burnt/out) (UTC-8) | It’s still a mess but it’s on this branch if anyone is curious https://github.com/ConnorBaker/cuda-packages/compare/main...fix/runpath-order-matters-and-cuda-compat-gets-clobbered | 06:56:57 |
 SomeoneSerge (back on matrix) | Let's schedule a call to discuss how to go forward with stdenv support, setup-hooks, wrappers, config.cudaSupport, localSystem/pkgsCross, clang support, and out-of-tree override-ability of manifests and toolkit components https://crab.fit/cudapackages-ng-781527

| ruro | connor (he/him) (UTC-7): SomeoneSerge (Gand St. Pieters) sorry to keep annoying you guys, but could you respond to the above question? Alternatively, "we are too busy right now, you'll have to figure it out on your own" is also an acceptable answer))) | 14:37:45 |
