| @zopieux:matrix.org | Looks like https://hydra.nixos-cuda.org/ is down? | 15:32:25 |
 Gaétan Lepage | Yes, the web interface has been flaky today. I'll try to restart the box. | 20:26:20 |
| Gaétan Lepage | Seems up, for now at least | 20:38:02 |
| @zopieux:matrix.org | Thanks! | 20:38:43 |

https://github.com/NixOS/nixpkgs/pull/498612 Would it be helpful to have a repackaging guide for the GPU driver? | 04:38:48 |
| Gaétan Lepage | FYI: The default cudaPackages version was updated from 12.8 to 12.9
I tested core packages, but I would not be surprised if regressions were to show up. Feel free to report them here.

Would it be helpful to have a repackaging guide for the GPU driver? Could you clarify what you mean by 'repackaging' and what specific scenarios the guide would cover? | 16:54:40 |
| Kevin Mittman (jetlagged/UTC-7) | Well for example there is a reference to bumblebee but https://docs.nvidia.com/datacenter/tesla/driver-installation-guide/latest/optimus-laptops-and-multi-gpu-desktop-systems.html | 17:31:50 |

 connor (he/him) | Gaétan Lepage: would you have the bandwidth to review https://github.com/NixOS/nixpkgs/pull/497675? | 00:26:38 |
| Gaétan Lepage | For sure! The diff is fairly trivial. The bulk of the job will be the testing.
yorik.sar this is a good candidate for testing the new GitHub app on our infra. | 00:34:39 |
| Gaétan Lepage | FYI: The PR updating jax to 0.9.2 and the rest of the ecosystem with it (22 commits 🫠) has finally been merged! (after 2 months of efforts)

| Gaétan Lepage | Do we agree that pytorch got their upper bounds wrong?
https://github.com/pytorch/pytorch/blob/v2.11.0/torch/utils/cpp_extension.py#L75
https://docs.nvidia.com/cuda/archive/12.9.1/cuda-installation-guide-linux/index.html#host-compiler-support-policy
GCC 14.x should be supported with cuda 12.9 | 14:46:42 |
| Gaétan Lepage | Also, it's unclear why this only blows up in torchvision and not in torch itself... | 14:48:33 |
| Gaétan Lepage | Looking for reviewers on:
| 21:39:29 |
| Gaétan Lepage | 🔥 PyTorch 2.11.0 (+ torchcodec 0.11.0) 🔥
Changelog: https://github.com/pytorch/pytorch/releases/tag/v2.11.0
PR: https://github.com/NixOS/nixpkgs/pull/502810
PR tracker: https://nixpkgs-tracker.ocfox.me/?pr=502810
Notable changes on the nix packaging side:
rocmSupport for torchcodecrocmSupport for torchaudio- revamp of the
torchaudio derivation, addition of testing
- Addition of
torchaudio.gpuCheck
This one only took me 4 days 🚀 I hope it doesn't break too many things 🥸 | 23:34:55 |

| Gaétan Lepage | Update, indeed, they messed it up: https://github.com/pytorch/pytorch/commit/39565a7dcf8f93ea22cedeaa20088b24ff6d2634 | 10:29:17 |
