 tpw_rules | anybody thought about how to have several versions of cutensor? | 01:33:16 |
| tpw_rules | for now there's only two old ones and they are auto-selected by what cuda toolkit. anyone remember why? | 01:33:28 |
| tpw_rules | FRidh: ^ | 01:36:48 |
 FRidh | I don't know. I suppose more can be added, it's just work to be done. | 08:01:40 |

| tpw_rules | where is a link to the hercules instance again? | 01:47:12 |
| tpw_rules | i found it but it seems like something is wedged: https://hercules-ci.com/github/SomeoneSerge/nixpkgs-unfree | 01:54:44 |
| tpw_rules | any idea why recent builds haven't completed? was there a staging merge a while ago? | 01:54:56 |
| tpw_rules | Someone S: ? | 02:05:42 |
 SomeoneSerge (back on matrix) | Oh wow. I'll have a look | 17:22:38 |
| SomeoneSerge (back on matrix) | Agent systemd service was somehow failing to resolve some domain names since October 22. I restarted it, seems to be online now | 17:27:19 |
| tpw_rules | it looks like things are better now? i guess now i just have to be patient for the builds | 19:14:31 |

| breakds | Hi! First I would like to say "thank you" to the Nix CUDA maintainers and the community! | 16:47:27 |
| breakds | I am trying to build pytorch with CUDA 11.08, and it complaints about cudnn:
at /nix/store/171cjmpyl45dz6dy818i3kf7x3nijkpg-source/pkgs/development/libraries/science/math/cudnn/generic.nix:28:1:
27|
28| assert useCudatoolkitRunfile || (libcublas != null);
| ^
29|
Being not quite familiar with how CUDA libraries are packaged, I am wondering since cudaPackages_11_8 does not seem to have libcublas, should I turn on useCudatoolkitRunfile (it is false by default) for CUDA 11.8? Judging from the name, it seems to suggest that I can find libcublas files from the cudatoolkit itself, am I wrong?
Thanks a lot!

| SomeoneSerge (back on matrix) | Ouch. This is actually a quite embarrassing overlook | 19:57:20 |
| breakds | Thanks for taking a look at this. Is it that cuda 11.8 should be handled differently? | 20:00:20 |
| breakds | https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/science/math/cudnn/extension.nix#L11 I am looking at this line | 20:00:33 |
| breakds | Not sure why there is a difference between 11.4+ and 11.4- | 20:01:20 |
| SomeoneSerge (back on matrix) | No, it's much simpler than that:) https://github.com/NixOS/nixpkgs/pull/200426 | 20:02:29 |
| breakds | Thanks for the fix! I need to learn more about how cuda packaging works. | 20:03:59 |
| SomeoneSerge (back on matrix) | Regarding this particular issue: you probably already found this, but the redist packages' attributes (like libcublas) are populated from a json file, stored right in the repo. With every release we download the json "manifest" file from nvidia and keep it as is | 20:13:37 |

With every release we download the json "manifest" file from nvidia and keep it as is Thanks for the explanation! It makes sense to me now. | 20:25:42 |
| breakds | A separate question, as I read from https://discourse.nixos.org/t/announcing-the-nixos-cuda-maintainers-team-and-a-call-for-maintainers/18074 , is x86_64-linux computing cycle still needed for github actions? I have a spare RTX 3080 not attached to any machine at this moment, not sure what is the best way to make it useful to the project. Shall I build a machine to run github actions? | 20:35:33 |
