 Jonas Chevalier | In reply to @connorbaker:matrix.org
Jonas Chevalier: I’d like to sponsor a GPU (CUDA) instance for nix-community so we can verify runtime behavior of things like PyTorch. Any ideas how much that would cost (or if Hetzner provides a discount for open source projects)? Thanks so much 🙏
Hetzner has some discounts that work more like a fixed credit they renew every year. The NixOS foundation has part of an ARM box covered by it, the nix-community project nothing so far.
Do you have an amount in mind that would work for you or your employer? Maybe we can pool it with other companies to cover the costs.
Feel free to DM me if you want to talk privately about the money matters. | 09:51:27 |
 connor (burnt/out) (UTC-8) | At least for the foreseeable future it’s going to be more out of pocket for me :/
I can put up an additional 250 EUR a month for a few months at least to get something, anything going
When’s the billing cycle for Hetzner stuff? | 23:58:50 |

 emily | Darwin builder
13:56 up 6 days, 14:28, 2 users, load averages: 33.73 36.94 36.14
| 13:56:48 |
| emily | cc Gaétan Lepage? trying to test channel-blocking 24.11 / 25.05 stuff | 13:57:02 |
| emily | it's >3× overloaded | 13:57:10 |
 Gaétan Lepage | Killed | 13:57:20 |
| emily | ty | 14:05:44 |
| emily | load average on the Darwin builder is 55 right now. maybe the default cores/max-jobs need tweaking? | 21:23:14 |
| emily | (I am not sure how they apply to remote builders though) | 21:23:19 |
| Gaétan Lepage | I'm responsible for 5 LAV now | 21:23:29 |
| emily | looks like it is mostly C and Rust stuff right now 😅 | 21:24:04 |
| emily | Rust is particularly bad about eating up cores (it doesn't even support load limit) | 21:24:29 |
 Austin Horstman | yeah... i got a few things i build all the time that are rust projects and my computer just crawls | 23:44:35 |
| Austin Horstman | it's annoying | 23:44:41 |
| emily | I think they might have jobserver support, or at least be working on it. | 23:44:52 |
| emily | that would be the ideal solution | 23:45:07 |
| emily | https://doc.rust-lang.org/rustc/jobserver.html | 23:45:19 |
| Austin Horstman | i'm not too famliar with it, so is the jobserver shared among all the different builds you might be running? | 23:47:30 |
| emily | the Nix daemon should implement a job server based on a configured global load limit, let it through the sandbox, and pass down MAKEFLAGS pointing to it | 23:47:33 |
| emily | then GNU Make, rustc, and others would ask it for free slots before starting build jobs, essentially | 23:47:54 |
| Austin Horstman | that sounds great | 23:48:04 |
