I am wondering what is the status with houdini on apple silicon?

is everything working?
what isn't?
would you be able to use it for production in it's current state?
what's the performance in certain areas like fluids, vellum, pyro, karma,..?

thanks

We are keeping an up-to-date list of issues here: https://www.sidefx.com/forum/topic/83312/ [www.sidefx.com]

The Apple silicon build is still not production ready and is not supported by us for production use. We are close, but not quite there yet.

Some users have posted their performance results here [www.sidefx.com] and here [www.sidefx.com].

Thanks!

It's just that the last entry in here [www.sidefx.com] is from Aug. 24, 2022 from yourself.
That's why I got curious if there is some more recent info.

Yeah out of curiosity I also wanted to know if Karma XPU support could come onto Apple Silicon by end of the year?

Heard that it's extremely fast on windows!

XPU already works on Apple Silicon, but currently is CPU-only (meaning it does not use the GPU).
We have future plans to support the GPU on Apple, but they're not immediate sorry.

I use it daily in production, fwiw. But yes looking forward to a full featured Karma XPU

So if you wanna use XPU it's faster on the non-Silicon Mac version of Houdini?

XPU is significantly faster if you have a powerful NVidia GPU. Other GPUs are not supported (yet?)

OpenCL acceleration is still possible on Apple silicon and has been present in every public release of our Apple silicon builds.

I've tested KarmaXPU on my M1 Ultra and even though it is only utilising the CPU, the speed is still very impressive for CPU only. So I can only imagine that being significantly better with the GPU compatibility.

that sounds very promising!

how is the GPU utilization/performance (opencl?) in pyro, flip, vellum,.. ?
