 Benjamin Isbarn | I'm not using any overlay for that purpose right now. Good point regarding the global override, will do that ;). So the cudaCapabilities would affect packages like the cudart, cublas etc. I guess i.e. what features it will consider available and thus use? the in theory this should yield better performance for the aforementioned libraries? | 07:03:05 |
 connor (burnt/out) (UTC-8) | Read https://nixos.org/manual/nixpkgs/stable/#cuda -- Jetson isn't built by default and pre-thor uses different binaries so you need to make sure cudaCapabilities is set correctly; you'll get faster builds, smaller closures, and (possibly) better performance if you specify the exact capability | 07:36:40 |

 Gaétan Lepage | VLLM is now 0.15.1 (latest version) | 11:11:17 |
 cameronraysmith | SomeoneSerge (back on matrix): let me know if the updates to https://github.com/NixOS/nixpkgs/pull/488199 captured what you suggested. No rush: thanks! | 21:03:44 |

This PR should fix the last failing gpuCheck instance, i.e. python3Packages.triton.gpuCheck: https://github.com/NixOS/nixpkgs/pull/488887
I discovered one of our beloved dlopen instance in triton. We didn't know about it since then... This PR fixes it too. | 23:39:42 |

| connor (burnt/out) (UTC-8) | Gaétan Lepage: there's a merge conflict and I need to rebase, but IIRC something like https://github.com/NixOS/nixpkgs/pull/485208 is necessary to make CUDA 13 the default.
I still need to do the same for the PyCuda PR I have: https://github.com/NixOS/nixpkgs/pull/465047. Apologies that's taking me so long. | 18:56:11 |
| 12 Feb 2026 |
| Gaétan Lepage | Ok thanks! I should get a notification when you'll have rebased. | 07:52:34 |

Do we want to drop it as an input to torch soon? Gaétan Lepage | 23:01:56 |

 Kevin Mittman (UTC-8) | Is there an hardcap on input tarball size? Considering splitting a particularly large one into multiple components | 01:54:03 |
| connor (burnt/out) (UTC-8) | Not that I’m aware of. But such a change would require some rework on the Nixpkgs side to recombine sources or know which components to pick (which isn’t necessarily bad, just a thing that would need to happen). | 17:20:26 |

| Kevin Mittman (UTC-8) | Broken in what way? Which version is it 590.48.01 ? | 03:13:32 |
| connor (burnt/out) (UTC-8) | The drivers are maintained by a different team -- we are the NixOS CUDA team | 04:19:31 |
