Which net is being use for lc0? Also, how is lc0 configured for 4CPU?

11258 as you've recommended.
Lc0 is only using 1CPU as noted.

Cheers,
Graham.

So 11258-112x9-se? For 4 CPU you could use 4 threads (-t 4).

Yes - 11258 112x9-se.
Trying to use this version of Lc0 with more than 1CPU leads to crashes.

Which version of lc0? Am not able to reproduce in my environment.

This is 0.20.1.
I've not tried 0.20.2 yet.
