 Mic92 | https://hydra.nixos.org/build/331695810/nixlog/1 matches the description | 07:13:12 |
| Mic92 | If it's not finished in 90 min, I will deploy | 07:58:18 |
| Mic92 | I also figured out why kernels are not build on non-big-parallel machines | 07:59:05 |
| Mic92 | The json parser for derivations wasn't taking structured attrs into account | 07:59:37 |
| Mic92 | * I also figured out why kernels are build on non-big-parallel machines | 07:59:48 |
 hexa | ugh, kernel builds on 2 cores are no fun | 08:08:19 |
| Mic92 | Classic bug. I did report a similar issue a month ago to nixbuild.net | 08:09:40 |
| hexa | Redacted or Malformed Event | 08:10:47 |
| hexa | I don't think we want to under these circumstances | 08:11:08 |
| hexa | if we restart it gets a big-parallel build slot and will be done much quicker | 08:12:01 |
| Mic92 | Okay, than lets roll | 08:17:29 |
| hexa | do you need any help deploying? | 08:17:49 |
| Mic92 | No. I have all closures already cached | 08:18:05 |
| hexa | cool | 08:18:08 |
| Mic92 | Fix works: https://hydra.nixos.org/machines | 08:40:22 |
| Mic92 | hopeful-rivest now gets the linux build instead | 08:40:34 |
| hexa | also looks like jobs stay much shorter in receiving outputs now | 08:51:08 |
| hexa | so that works, too at first glance | 08:51:17 |
| Mic92 | Yeah. Ingestion is now a bit busier. But not as busy as in the old days. | 08:53:30 |
| hexa | 
Download I think we need to tune the load on hopeful-rivest better now | 10:02:45 |
| hexa | 7 browsers and 3 kernels is a bit much | 10:03:03 |
 K900 | I wonder if less but bigger jobs will be better now | 10:03:20 |
| hexa | Redacted or Malformed Event | 10:03:24 |
| hexa | https://github.com/NixOS/infra/pull/1093 | 10:09:46 |
| hexa | 6x20C (down from 10x20C) for aarch64-linux | 10:10:04 |
| hexa | 6x24C (up from 4x24C) for x86_64-linux | 10:10:17 |
| hexa | that's ~1.5 times the core count of the machine | 10:10:47 |
| K900 | Now that we have pressure info, we should really start taking that into account when scheduling | 10:10:49 |
| hexa | we kinda do | 10:11:01 |
| K900 | Would make life a lot easier I think | 10:11:03 |
