 das_j | well, we also do parallel evals, so not doing that will probably help :D | 15:58:21 |
 ajs124 | and we give our postgres a bunch of memory | 15:58:40 |
| das_j | yeah, to make the web interface more bearable | 15:58:56 |

well, we also do parallel evals, so not doing that will probably help :D parallel evals = distributed builds ...? I just ask because for me sounds the same...? | 15:59:21 |
| ajs124 | also made a bunch of errors disappear. although that probably wasn't the memory but the connection limits etc. | 15:59:21 |
| das_j | no, evals != builds | 15:59:50 |
| mbprtpmnr | well, i have 2 vps with nixos, can i make parallel eval? | 16:00:14 |
| das_j | you can't | 16:00:22 |
| das_j | it will always evaluate on one host | 16:00:27 |
| das_j | you can do multiple parallel evals on the host, but it's always limited to one host | 16:00:48 |
 cransom | evaluating nixpkgs is going to be a ginormous memory hog compared to a single system config. | 16:00:54 |
| mbprtpmnr | oooh, parallel evals on the same machine, not distributed...understood... | 16:01:26 |

Big problem here .... :)))
Sep 23 18:51:50 nixos-server kernel: Out of memory: Killed process 69971 (hydra-eval-jobs) total-vm:759624kB, anon-rss:666904kB, file-rss:0kB, shmem-rss:0kB, UID:122 pgtables:1476kB oom_score_adj:0 Thought something like that would happen :) | 16:01:48 |
| Rick (Mindavi) | Yeah, as I said, nixpkgs is not a very good idea :) | 16:02:46 |
| das_j | you can do nixpkgs, but the small variant. that's a lot more doable | 16:03:19 |
| das_j | instead of release.nix you take release-small.nix | 16:03:28 |
| Rick (Mindavi) | Maybe try patchelf for a start, I think the hydra manual also describes that | 16:03:42 |

Yeah, as I said, nixpkgs is not a very good idea :) but...with fu+ how can i eval my flake system configs, is verry small ... | 16:03:41 |
| Rick (Mindavi) | I don't know, maybe someone else can help with that | 16:04:41 |
| mbprtpmnr | I see that Hydra can build and eval also flakes... | 16:05:40 |
| das_j | patchelf is built with flakes: https://hydra.nixos.org/jobset/patchelf/master#tabs-configuration | 16:06:46 |
| mbprtpmnr | I try rn... | 16:07:53 |
| mbprtpmnr | Yeah, something is happening here :) | 16:11:14 |
| mbprtpmnr | das_j: Thanks... https://hydra.mbprtpmnr.xyz/jobset/patchelf/patchelf#tabs-jobs | 16:12:48 |
| mbprtpmnr | Works :) | 16:12:58 |
 tomberek | mbprtpmnr: you most likely don't want to start building a full nixpkgs release... what you have now is much closer to what you need | 18:23:13 |
| mbprtpmnr | Well, I just want to build my system flake configs... | 18:23:51 |
| mbprtpmnr | But... Is something wrong here... https://hydra.mbprtpmnr.xyz/jobset/systems/systems#tabs-errors | 18:25:09 |
| cransom | exit code 1, check journald as it probably crashed. | 18:36:41 |
| mbprtpmnr | again, oom-kill ... | 18:37:11 |
