Houdini 22.0.368.
Tried compiling, went through every single precompile lap before telling me it failed. Took 1hr 45min.

22.0.398 has this fixed

I do have KARMA_XPU variables set - most notebly KARMA_XPU_THREAD_COMPILE = 1. I disabled all the KARMA_XPU variables for now and now the karma_cc.exes are gone. only one karma.exe remains which runs at a steady 2-4% cpu load.

cool
at least the karma_cc.exes are gone

I ran precompile on Windows 11 with the following configuration: Intel Core Ultra 7 265k (8P 12E), Nvidia RTX 5080 with 610.88 driver using Houdini 22.0.401
Total time taken was 4 hours 20 minutes 9 seconds. Average core usage was 20%. Usage was almost entirely P-cores and occasionally spiked to all P cores, but was only using 2~4 most of the time.

I'm starting to suspect some kind of file-locking issue within the nvidia cache.

I deleted any existing cache for H22 and did a fresh run. It took about 7.5 hours (with cpu usage around 2-3%)!

Good to know

I have seen this behavior before where the cpu usage is somewhat unpredictable. It‘s really weird.

Yes it is weird :/
Hopefully I'll be getting an e/p-cores machine soon so I can debug more closely. Will report back findings here.

thanks all

When starting the caching, multiple (i guess 64) karma_cc.exe start up plus the houdini.exe

This is strange, it should only be starting 1 karma.exe (and does so on my windows machine)
Do you have some KARMA_XPU_... environment variables set by chance?
