20 New NN Engines has been reported to the TCEC

[AndrewGrant]

The Baron does not use neural nets (yet). The version registered to TCEC is a NUMA aware compile of 3.44
Richard.

Is NUMA awareness currently required at TCEC?

Condition for required: Running windows with 64+ threads. Without NUMA awareness you can't get optimal thread to CPU distribution.
Condition for recommended: Always

Thanks. So for TCEC, with 43 threads on a 2x22 core machine w/o HT, can I expect that "usually" each of the 43 threads will get its own core?

I'll take your "Usually" and raise it to "So long as Windows is not completely insane", then yes, each thread should get its own core (after some time).
