@julius:mtx.liftm.deˈt͡sɛːzaɐ̯ Jonas Chevalier: The link to the eval you posted on that PR 404s. 10:35:07
@zimbatm:numtide.comJonas Chevalieryeah, I renamed the jobset to https://hydra.nix-community.org/jobset/nixpkgs/cuda-nixos-unstable10:36:25
@hexa:lossy.networkhexa (UTC+1)awesome10:56:28
@ss:someonex.netSomeoneSerge (back on matrix)Yesterday seems a bit hazy...12:30:22

Something like this: https://github.com/nix-community/infra/pull/1335
I'll look into updating cuda-release.nix

H'm so in hydra you "create a jobset" somewhere like in a web ui before you merge the terraform configs?

@ss:someonex.netSomeoneSerge (back on matrix)* H'm so in hydra you "create a jobset" somewhere like in a web ui before you merge the terraform configs? Or the tf config is the whole thing but you deployed it manually?12:38:17
@ss:someonex.netSomeoneSerge (back on matrix)

Isn't that a gem:

❯ hydra-eval-jobs --help
error: unrecognised flag '--help'
Try 'hydra-eval-jobs --help' for more information.

@hexa:lossy.networkhexa (UTC+1)faissWithCuda pls 😄 16:56:57

faissWithCuda pls 😄
Why not just https://github.com/NixOS/nixpkgs/pull/324379/files#diff-b3a88f86f137f8870849673fb9b06582cb73937114ee34a61ae5604e259829a5R37

@ss:someonex.netSomeoneSerge (back on matrix) Jonas Chevalier while at it, nobody is building import <nixpkgs> { config.rocmSupport = true; } either, and that one is free 17:14:56
@ss:someonex.netSomeoneSerge (back on matrix)The only reason not to build that with the NixOS Hydra is... to save resources17:16:20
@hexa:lossy.networkhexa (UTC+1)not sure how many jobs that will generate 17:17:40
@ss:someonex.netSomeoneSerge (back on matrix)Me neither 🙃17:21:54
@ss:someonex.netSomeoneSerge (back on matrix)

error: blackmagic-desktop-video has been due to being unmaintained

it has been and now it isn't

not sure how many jobs that will generate
❯ nix-eval-jobs --expr 'import ./pkgs/top-level/release-cuda.nix { }' --force-recurse | wc -l
...
138452

(not counting eval errors)

@hexa:lossy.networkhexa (UTC+1)so all of them19:13:28
@hexa:lossy.networkhexa (UTC+1)if there was a cache behind nix-community hydra, than you'd be mirroring cache.nixos.org effecitvely19:13:45
@hexa:lossy.networkhexa (UTC+1) * if there was a cache behind nix-community hydra, than you'd be mirroring cache.nixos.org effectively19:13:47
@ss:someonex.netSomeoneSerge (back on matrix)Yeah... Ideally we'd have a solution that evaluates the full DAGs for vanilla and cuda nixpkgs, starts building cuda from the leaves (ehhh, the roots), and always suspends the build if it hash matches the vanilla hash19:23:45
@connorbaker:matrix.orgconnor (burnt/out) (UTC-8)Is there an open collective for the community hydra instance19:24:40
@connorbaker:matrix.orgconnor (burnt/out) (UTC-8)If they’re going to be building CUDA packages I definitely want to contribute lol19:25:56
@matthewcroughan:defenestrate.itmatthewcroughanHow can onnxruntime use more than 64G of memory with 12 cores22:28:09
@matthewcroughan:defenestrate.itmatthewcroughanugh22:28:09
@matthewcroughan:defenestrate.itmatthewcroughanoh, maybe because I lack https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/development/libraries/onnxruntime/default.nix#L19122:30:58
@matthewcroughan:defenestrate.itmatthewcroughanI think it reaches a part of the build where it runs away22:31:15

Is there an open collective for the community hydra instance

yes, we spend it all on hardware: https://opencollective.com/nix-community

we could also explore hardware donation if you want to bring esoteric hardware to the build farm.
