 K900 | Try TARGET=GENERIC in makeflags? | 11:21:51 |
| K900 | https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs%2Fdevelopment%2Flibraries%2Fscience%2Fmath%2Fopenblas%2Fdefault.nix#L74 | 11:22:33 |
| K900 | Oh wait no it's doing something | 11:22:40 |
 Yureka (she/her) |
DYNAMIC_ARCH = setDynamicArch true;
| 11:23:12 |
| K900 | Might be easier to bisect tbh | 11:23:42 |
| K900 | That build system is fucked | 11:23:46 |
| Yureka (she/her) | 67d46b9a3b8d1fac159ac13666947f80942f20d8 is good | 11:24:34 |
| K900 | I'm not doing it right now | 11:24:54 |
| K900 | Don't have an aarch64 box that's fast enough | 11:25:07 |
| Yureka (she/her) | it's not much | 11:25:14 |
| Yureka (she/her) | I'm doing it | 11:25:16 |
| K900 | I currently have one overheated 3588 | 11:25:30 |
 Emil Thorsøe | overheated as in damaged physically? | 11:27:14 |
| K900 | No, just very inconveniently placed somewhere it's very hot | 11:27:51 |
| Yureka (she/her) | https://github.com/NixOS/nixpkgs/pull/450106 | 11:36:38 |
| K900 | So do we have to bisect into openblas now | 11:37:11 |
| Yureka (she/her) | or just revert and do that later? | 11:37:51 |
| K900 | Depends on how big the bisect is I guess | 11:38:27 |
| K900 | Do you want to try it? | 11:38:47 |
| Yureka (she/her) | big | 11:39:09 |
| Yureka (she/her) | 558 commits | 11:39:17 |
| K900 | And how long does it take to fail? | 11:39:28 |
| Yureka (she/her) | not very long, but looking at the commits between openblas .30 ... .31, it's likely that broke and was fixed more than once in between | 11:41:37 |
| K900 | Ugh | 11:42:13 |
| Yureka (she/her) | just the fact that this package is so irreproducible in the first place, and they added full new code paths for the neoverse platform in between | 11:42:52 |
| Yureka (she/her) | Redacted or Malformed Event | 11:42:55 |
| Yureka (she/her) | 
Download foo.png | 11:43:32 |
| Yureka (she/her) | it likely broke at a different point on the Ampere vs the M1 Pro | 11:43:41 |
| Yureka (she/her) | and the dynamicArch ? null suggests the people who wrote this package initially fully intended the non-reproducibility | 11:44:25 |
 dramforever | does openblas build different objects with different -march | 11:44:33 |
