 ereslibre | Glad it worked! :) | 05:48:55 |
| SomeoneSerge (back on matrix) | luke-skywalker: looking forward to read the blog post xD | 12:03:57 |
| luke-skywalker | blog post?
Shouldnt everyone have the joy of fighting through those dungeons of rabbit holes and come out the other end with some awesome loot? 😊
Will do when I find the time to write it down as a guide / article or make a PR to either rke2 or nvidia-container-toolkit. Might even wrap it into its own system module. But main thing is available time since this is just one of the stepping stones to a system to federate distributed "AI" capabilites.
Dont actually want to be too public before I have a working "kernel" of the envisioned system. | 15:22:21 |
| ereslibre | I might be able to open a PR to enable CDI on containerd this weekend | 21:14:48 |
| luke-skywalker | FYI with the virtualisation.containerd module (not the one used by rke2) it works already out of the box. | 21:16:15 |

| ereslibre | luke-skywalker: unless I’m missing something, nothing is setting https://github.com/cncf-tags/container-device-interface?tab=readme-ov-file#containerd-configuration, right? You had to do this manually, right? | 06:06:26 |
| luke-skywalker | funnily from all the detours I took to make ti work, I though rke2 was doing that, but I think I must have done that by hand and forgot about it.
So yes you need to profide a config.toml.tmpl with nvidia-cdi defined pointing to the runtime binary and set [plugins."io.containerd.grpc.v1.cri".cdi]
Could you give me the TLDR why using image: nvcr.io/nvidia/k8s-device-plugin:v0.17.x
fails with glibc issue.
my understanding it was build build with a newer version of glibc that on my system (2.40)? ANy way to solve this or is it ok to simply stick to 16.x?

| luke-skywalker | ui interesting. How does it compare to vllm?
I see it supports device maps. Is that for pipeline parallelism so GPU devices on different nodes / machines as well?
Is it somehow affiliated to mistral-ai or whats the reason for the name of the library? ;) | 14:12:59 |
| luke-skywalker | also does that work on k8s clusters? 🤔 | 14:13:43 |
 Gaétan Lepage | I haven't used it much myself as I don't own a big enough GPU.
According to me, it is not affiliated to Mistral (the company). I guess that it's the same as "ollama" and Llama (Meta). | 15:43:10 |
| luke-skywalker | its getting better still though. Now switched from Daemonset deplyoment of the device plugin to helm deployment with custom values. This made it possible to also enable time slicing available GPU 🥳 | 16:10:02 |
| luke-skywalker | thx for the info, yeah the same as ollama was my assumption.
Guess ill stick to vllm depoyment with helm on k8s. | 16:37:54 |

| ereslibre | luke-skywalker: yes, glibc is not forwards compatible, only backwards compatible.
