 le-chat | I'm just copying/symlinking something like libcuda* lib*nvidia* libnv* from the directory where the toolkit put them.
Once upon a time I've been required (for trtexec) to run patchelf --add-rpath /run/opengl-driver/lib on these copies, but that was on older Nixos, I don't know if it's necessary now. | 19:24:19 |

Ftfy Yeah, @glepage:matrix.org: why not now? | 09:01:01 |
 Gaétan Lepage | Well, because we unfortunately are quite busy with a lot of maintenance work. It is hard to find some time to work on those more long-term projects. | 09:32:42 |

Well, because we unfortunately are quite busy with a lot of maintenance work. It is hard to find some time to work on those more long-term projects. I'd be happy to help if there is anything I could do to speed this up. | 12:00:04 |

| rpcruz | Hey guys, does anyone else have a setup with A100 (or some such) that require nvidia-fabricmanager?
Could you maybe share with me the relevant .nix configuration bits?
(If using a relatively modern NixOS - 25.05 or 25.11)
hardware.nvidia.datacenter.enable=true produces for me a broken nv-fabricmanager with undefined symbols.
I managed to make it work by packaging nvidia-fabricmanager myself, but it is a bit ugly and as a novice I am not sure everything is well done.
If anyone has a configuration with nvidia-fabricmanager that could share with me that would be great...! | 16:05:31 |
 connor (burnt/out) (UTC-8) | A lot of the functionality gated behind datacenter-grade GPUs or multi-GPU setups is out of the reach of the maintainers at the moment as we’ve just recently been able to get a Hydra set up to build packages and run a few GPU checks. Part of the quick iteration time I’ve had in the past is because I own a 4090 and so can benchmark and test quickly. But for bigger stuff, the only approach I’ve had any luck with is using Lambda Labs to rent multi-GPU instances for fairly cheap and try Nix-built binaries on them. But that doesn’t test using NixOS as the host system or any other number of features unique to the hardware (or even specific code paths).
If you have such hardware or have access to it, please don’t hesitate to open PRs. Access to hardware (among other things like time and burnout) are big blockers for us supporting more stuff. We can always coach or provide feedback on packaging! And we can certainly use such an opportunity to update (or make) contributing documents. | 19:01:11 |
