Is this team involved in flox/nvidia partnership ?
(See https://flox.dev/cuda/)
I guess so since the nixos foundation also is, but there is no mention of this team or its amazing work. Ron mentioned them here https://discourse.nixos.org/t/nix-flox-nvidia-opening-up-cuda-redistribution-on-nix/69189/7 | 20:01:06 |
| matthewcroughan | Is there a rocm room? | 20:54:56 |

 SomeoneSerge (matrix works sometimes) | The negotiations with NVIDIA have been run by Flox (although in parallel with many other companies' simultaneous inquiries). Ron kept us, the Foundation, and the SC in the loop, and offered both legal help and workforce. The current idea roughly is that the CUDA team gets access to the relevant repo and infra, and work closely together with Flox to secure the position and a commx channel to NVIDIA. | 23:26:05 |
 hexa | What were the blockers for setting this up within the NixOS Foundation? | 23:54:32 |

 Tristan Ross | From what I recall, it was something to do with having a legal entity in the US. If the foundation was registered in the US, then it would've been fine. This has been going on since at least Planet Nix, glad to see it finally pull through. | 00:03:41 |
|  @ihar.hrachyshka:matrix.org joined the room. | 00:09:51 |
| connor (burnt/out) (UTC-8) | Will try to take a look later | 00:10:55 |
| connor (burnt/out) (UTC-8) | You’d probably need to override writeGpuTestPython to use the Python package set you specify. It’s inside cudaPackages so it has no way of knowing what scope you’re using it in. | 00:12:26 |
| connor (burnt/out) (UTC-8) | They’re still mostly okay; I’ve been exhausted recently so haven’t been awake too early (I was up at 3am this morning but that’s something else)
If we can do something closer to 8 that might be easier; Kevin Mittman how are you with morning meetings? It’d be good to catch up and discuss what’s been done so far with the database project Serge’s been working on. | 00:14:16 |
| connor (burnt/out) (UTC-8) | NVIDIA’s EULA effectively prohibits running CUDA binaries they release on non-NVIDIA hardware (see 1.2.8: https://docs.nvidia.com/cuda/eula/index.html#limitations) | 00:20:07 |
