 Marie | hello, I've raised a PR for access to the community builders: https://github.com/nix-community/infra/pull/1742
I don't own a darwin machine, but I'd like to make sure some packages i maintain also work on darwin.
I'm not sure if I qualify for the "well-known" requirement yet or if someone would vouch for me. | 13:12:48 |
|  @eisfunke:eisfunke.com changed their display name from Nicolas Lenz to Nicolas. | 13:40:06 |
 magic_rb | If it helps, ive seen you around a lot in the past few months and you seem nice, dont know if i qualify for the well known either | 13:50:35 |
 emily | I'm happy to vouch if you'll be mindful of the shared resource (be mindful of your cores/jobs settings and make sure you don't overload the machine etc.) | 13:54:27 |
| magic_rb | * If it helps, ive seen you around a lot in the past few months and you seem nice, dont know if i qualify for the well known either, but yeah id vouch | 13:54:32 |
| emily | and assuming you've read the notes in https://nix-community.org/community-builders/ | 13:55:01 |
| emily | (I personally don't use the builders as direct remote builders but just SSH in for that reason) | 13:55:13 |
| Marie | thanks, I'll keep that in mind, thats common sense for a shared machine to me :) | 15:35:31 |
| Marie | and yes, I've read the notes | 15:35:43 |
|  Vova Kryachko joined the room. | 15:58:49 |
|  sinan changed their display name from sinan (we're so back) to sinan. | 16:00:09 |
| sinan changed their profile picture. | 16:00:11 |
| Vova Kryachko | Hey folks, anyone able to review this PR(unable to assign reviewers)?

| emily | Gaétan Lepage: x86 Linux builder is at >100% CPU usage | 16:15:30 |
 Gaétan Lepage | Yes I'm building torch | 16:15:49 |
| Gaétan Lepage | I can kill it. This is endless | 16:16:03 |
| Gaétan Lepage | (I made sure to --max-jobs 1 --cores 0 so I hope the LAV is not over 24) | 16:16:36 |
| emily | --max-jobs 1 --cores 0 will frequently make load average go > nproc | 16:17:55 |
| emily | since the leaf build children are never the only process running on the system | 16:18:24 |
| emily | * since the leaf build children are never the only processes running on the system | 16:18:33 |
| emily | load average: 24.65, 25.85, 26.11 | 16:19:04 |
| Gaétan Lepage | Is 25.5 (current 15min LAV) significantly worse than 24? | 16:19:40 |
| Gaétan Lepage | I can set --cores n-1 next time if this makes a tangible difference. | 16:19:57 |
 Max | make invocations that don't set `-l` are a crime against humanity | 16:20:08 |
| emily | yes, an overloaded system thrashes endlessly and makes it take 10 seconds to fork a single command etc. | 16:22:26 |
| emily | not that 23 is great either on a shared resource | 16:22:33 |
| Gaétan Lepage | Ok I thought that context switching was negligible for LAV~n_cores. | 16:23:40 |
| Gaétan Lepage | Ok it's finally ending... 1h50min to build this monster on 24cores... | 16:24:12 |
