LC0 (and other NN-engines) testing

 

Playing conditions:

 

Hardware: i7-8750H (Hexacore) Notebook with RTX 2060 GPU, Windows 10 64bit, 16GB RAM

CPU-Speed: Stockfish with 97% CPU-Speed (to switch off the Intel Turbo Boost): 7.5 MN/s in starting-position, running on 11 threads.

GPU (used by LC Zero): Nvidia RTX 2060 (6GB). LC Zero calculates around 11500 n/s in the starting position (I used the MSI-Afterburner-tool to reduce the speed of the RTX-Card as far as possible) (measured with "go infinte") with Netsize 20x256, which means a Leela-Ratio (what is Leela Ratio? look here) of 1.3.The Leela-Ratio-value of AlphaZero (used a 20x256 net, too) in the match vs. Stockfish 8 was 1.0 - so 1.3 is a high value, but acceptable.

Hash: 1 GB for AB-engines and 1.000.000 size of NNCache for Leela

GUI: LittleBlitzerGUI, draw at 160 moves, resign at a -700 cp evaluation.

Tablebases: none

Openings: 4 SuperGM-moves. Download my 4-moves opening-sets and books here

Large Memory Pages: Off

Ponder: Off

Thinking time: 150'' (2.5 minutes) +1500ms (average game-duration: 8-9 minutes)
