hmmmm... very strange.
and if you let one of threadripper machines finish, what is the total time? 2 hours? 20 hours?
thanks

Ah wait -- I updated my display driver, made sure I wasn't in battery-save mode and now it's back in the slot:

OMG...
I'm glad its now working again, thanks for testing Jason.

Well the symptoms are just like before - only a fraction of the available CPU cores are used (about 20/64cores (128threads)). Also, the used cores do not seem to be maxed out but work at around 10-50%.

That just leaves ronald_a now.
I think we can try a few things
eg
- do you have some kind of power-save mode enabled on your computer?
- what if you do a KarmaXPU render using only the CPU (ie KARMA_XPU_DEVICES=embree), do all the cores light up then?
- what happens if you update to latest driver as well? (616.56 dropped on Wednesday)
- what happens if you set KARMA_XPU_THREAD_COMPILE=1 again? do you see all cores light up initially as you did originally? (it means it seems to parallelize when we fire up multiple processes, rather than multiple threads).
- what total time do you actually get? Perhaps task-manager is saying low-usage, but in reality its working fine?

I'm probably not the target audience with my RTX 3070 Laptop card, but:

At least we have 91% utilization of your CPU now. I'll try to bring the cost down further over the coming days/weeks.
some questions:
- is this a regression for you Jason? Or has it always taken this long? (ie even in H21?)
- whats the temperature like on your CPU while this is running? (something like HWinfo can report this). Is it possible the Laptop is old and the CPU is overheating/throttling?

I'm afraid, this still does not work for me.

What are the symptoms now? Are you able to post a screenshot like what Jason did?
Also, can you confirm you no longer have any KARMA_XPU_... environment variables set?

thanks
