A separate question, as I read from https://discourse.nixos.org/t/announcing-the-nixos-cuda-maintainers-team-and-a-call-for-maintainers/18074 , is x86_64-linux computing cycle still needed for github actions? I have a spare RTX 3080 not attached to any machine at this moment, not sure what is the best way to make it useful to the project. Shall I build a machine to run github actions? Hi breakds! Thanks so much for your generosity! Yes, we'd love to find a way to make it useful somehow. Oddly enough our primary bottleneck atm is CPU cycles. It turns out that running CIs (nixpkgs-upkeep, Someone S 's build CI) takes a bit of compute. I'm finding that build jobs frequently hit the free-tier 6 hour limit on GH Actions, so finding an x86_64-linux machine that could be home to a GH Actions runner would be great! | 09:11:05 |
| Samuel Ainsworth | I created https://github.com/samuela/nixpkgs-upkeep with the goal of ultimately running GPU-enabled tests in CI, but honestly we've had so many issues just keeping the packages building at all (only CPU required to build), that GPU-enabled tests haven't been the issue so far | 09:12:34 |
| Samuel Ainsworth | and of course Someone S may have other needs as well | 09:13:19 |
| Samuel Ainsworth | on the caching side, Domen Kožar has been incredibly helpful with the cuda-maintainers cache on Cachix (https://app.cachix.org/cache/cuda-maintainers#pull)! A lot of folks have him to thank for their setups working smoothly! | 09:15:04 |

| Samuel Ainsworth | anyone have any feature requests for GitHub? https://discourse.nixos.org/t/nixos-github-collaboration/23432 | 06:52:51 |
 tpw_rules | improved caching would be great. there have been some bugs there in the github actions that are ugly to work around and they would not fix | 15:31:53 |
| tpw_rules | also particularly for us, figuring out how to get cuda and stuff to work nicely in codespaces. (are nvidia codespaces includes in the free hours/) | 15:32:27 |
| tpw_rules | * also particularly for us, figuring out how to get cuda and stuff to work nicely in codespaces. (are nvidia codespaces includes in the free hours?) | 15:32:29 |
| Samuel Ainsworth | I'm not sure I understand... do you have concrete examples of these caching failures? what could GitHub do to help the situation? | 19:29:17 |
| Samuel Ainsworth | yeah having a free GPU in codespaces would be nice! unfortunately I imagine that would also be quite pricey for them | 19:29:51 |
 SomeoneSerge (matrix works sometimes) | Oh, not at all. Just that I don't think I had even one PR accepted without someone asking me to specify the platforms explicitly 🤣 But it also makes sense: the attribute is treated specially by hydra (and probably other CIs), so why leave it implicit | 21:32:51 |
| SomeoneSerge (matrix works sometimes) | "Caching" was my first thought as well, but probably we're talking about different caches. It's always about caching though | 21:34:22 |
| SomeoneSerge (matrix works sometimes) | Does anyone feel like following through with the 11.7 -> 11.8 bump? There were some packages with cmake configure failing =\ | 21:35:48 |

I'm not sure I understand... do you have concrete examples of these caching failures? what could GitHub do to help the situation? it's not possible to naïvely cache the store using the cache action because it can't restore the read only files. i'm not sure why they can't just extract the archive with sudo or whatever. it's work-around-able by manually changing permissions and shuffling stuff around but that's slow | 22:37:16 |

| Samuel Ainsworth | ahhhhhh I see. sounds a bit like https://github.com/NixOS/nixos-foundation/issues/25#issuecomment-1327892243 | 00:01:04 |
| Samuel Ainsworth | yeah, agreed that would be helpful | 00:01:14 |
| tpw_rules | yes. i'm not even clamoring for a global cache, i really just want the cache action to work nicely | 00:06:10 |
| tpw_rules | though a global cache would be great | 00:06:18 |
| tpw_rules | * though a global cache would be great. but fixing the cache action should be a very easy target | 00:06:36 |
| tpw_rules | i commented on that thread, thanks for pointing me to it | 00:09:09 |
 hexa | https://github.com/NixOS/nixpkgs/pull/202769 | 16:56:54 |
| hexa | can someone review this? | 16:56:59 |
| hexa | working on torchaudio and it would be neat to have this | 16:57:15 |
|  ahmed changed their display name from rh to ahmed. | 19:19:35 |
| 29 Nov 2022 |
| tpw_rules | hexa: running a nixpkgs-review cycle including CUDA stuff. planning to try the test suite too. expect something by tomorrow evening but i don't expect any major issues | 05:05:55 |
| tpw_rules | thank you for your patience | 05:06:53 |
