20 New NN Engines has been reported to the TCEC

[Chessqueen]

TCEC reported that 20 new NN Engines will be added among them Hannibal NN, Scorpio NN, and The Baron NN ! I wonder if the NN version of those engines will be stronger than their previous version? I believe that Larry is also considering making a NN version of Komodo as well. Hannibal is a very decent engine listed on the CCRL Report as 3155, lets see if the NN version will make it stronger.

Nightbot: Confirmed: Nemorino, Hannibal, ScorpioNN, Tucano, Wasp, Winter, Pirarucu, RubiChess, Marvin, Cheese, the Baron. Current estimate is between 18 and 22 engines.

What is interesting is that the Development of Leela has been spearheaded by programmer Gary Linscott, who is also a developer for the Stockfish chess engine along with Alexander Lyashuk.

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?

You seem to have misread - there will be 16-20 new engines, one of which will be a NN engine that isn't derived from Lc0.

Is NUMA awareness currently required at TCEC?

Required not. Recommended yes, as it is a dual-socket machine.

Ok. Is there a common estimate of the slowdown for a non-NUMA-aware engine on such a machine?

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

Torsten once tested that for me in one of the early TCEC editions. I don't rmember exactly how much, but it was significant (order of magnitude 10-20%).

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?
