macOS GPU resource sharing

[mzenz]

Is it possible to share GPU resources with Podman containers, similar to how Nvidia GPU resources can be shared with containers on Linux/Windows?

Please let us know, I haven't been able to find any info on how to do so.

We are working on this and it should be available in podman 5.1.

#22491

[fockem]

Is this future available right now because 5.1 is out now?

[rhatdan]

Well yes and know. You can switch to krunkit, but need to get the bugfix in podman 5.1.1

[fockem]

So install version 5.1.1 and then with Krunkit I can have a container use GPU resources.

Do you have some tutorial for this?

[sroecker]

I guess this can be marked as answered now since libkrun is bundled and the process is documented https://podman-desktop.io/docs/podman/gpu

Hey folks! I recently installed the latest versions of podman and podman-desktop via brew and still needed to brew install slp/krunkit/krunkit.

I'm seeing the same as @zoidyzoidzoid, I don't see libkrun anywhere in the podman-desktop install for 1.16.0 (installed from HomeBrew on an M1):

MacBook-Pro :: ~ % find /usr/local /opt/homebrew /Applications/Podman\ Desktop.app | grep -i krun
MacBook-Pro :: ~ %

I think I found the issue. The brew Formula here needs to be updated to include the krun binary, and maybe also the other files introduced in #23079

They're in the .pkg

@zoidyzoidzoid You're right. The podman releases in GitHub do bundle krunkit, but the brew version doesn't. If you only install podman-desktop but not podman, the first will detect that it's missing and will download it from a release, which does have krunkit bundled. If you install both from brew, podman-desktop detects that's already available and won't offer downloading it.

As you said, I think the brew formula for podman should be updated to include krunkit (cc/ @chenrui333).
