 emily | 15.4 has some weird issues btw | 00:13:35 |

| hexa | lun: looks like you didn't set the composable kernel packages to big-parallel after all? https://hydra.nixos.org/build/294295249 | 16:51:07 |
| 6 Apr 2025 |
 Lun | It's split into parts only some of which are marked big-parallel
https://github.com/NixOS/nixpkgs/blob/5c0edef29f64ca168f3d6ba0e944c2ae57f693bd/pkgs/development/rocm-modules/6/composable_kernel/default.nix#L8 | 04:57:16 |
| Lun | https://hydra.nixos.org/build/294295249/nixlog/26 _mha was on a 24 core machine so I think that part worked? Do more of the parts need set to big-parallel? | 04:59:26 |
 Vladimír Čunát | The machines have more cores, but you get -j based on the big-parallel flag. | 06:18:46 |
| Vladimír Čunát | Without the flag you only get 2 typically (on current hydra.nixos.org). | 06:19:11 |
| Vladimír Čunát | You can see on that linked page (another tab): https://hydra.nixos.org/build/294295249#tabs-buildsteps
that some of the builds took many hours. | 06:20:55 |
| Vladimír Čunát | * You can see on that linked page (another tab): https://hydra.nixos.org/build/294295249#tabs-buildsteps
that some of the builds took several hours, so those are probably candidate. | 06:21:21 |
| Vladimír Čunát | (I assume they do parallelize well.) | 06:21:33 |

| hexa | rebooting hydra for updates | 13:39:46 |
 John Ericson | hexa (signing key rotation when): once https://github.com/NixOS/hydra/pull/1456 passes, I think we're ready to do another update | 18:54:43 |
| John Ericson | CC Mic92 | 18:54:52 |
| John Ericson | that has all of the extra hydra.nixos.org work merged to master, and Nix 2.28 | 18:55:11 |
| hexa | John Ericson: cool, sounds like we can drop the nej pin then and migrate to master | 20:17:27 |
| John Ericson | we have a nej pin at the moment? | 20:17:59 |
| hexa | in nixos/infra? yeah | 20:18:44 |
| hexa | some breakage around constituents | 20:18:51 |
| hexa | * some test breakage around constituents | 20:18:59 |
| John Ericson | oh hmm | 20:22:35 |
| John Ericson | hexa (signing key rotation when): oh yes | 20:22:46 |
| John Ericson | as of the last PR, I have the lastest version of everything working together | 20:22:56 |
| John Ericson | I fixed the constituent globs test to have the change the that the h.n.o commit made to the other tests | 20:23:18 |
| hexa | exciting | 20:23:33 |
