Leela on CPU.

[Chris Kofinas]

I open this topic for all Lela fans which use Lela chess engine on CPU. Opinions,games,ratings e.t.c. Seems that small 6x64 nets from test server (like 9149) have the best performance on my low end dual core PC. Any opinions?

Well... I have a 9 year old AMD Phenom II X4 955 with 4 cores. Leela CPU-Version calculates only 50 nps there with the actual 192x15 nets. At the moment I test ID 462 against engines that are rated around ELO 2600 on CCRL. Even with the Restrictions of a CPU Leela can win against Ruffian 2.1 (Elo 2623 at CCRL) and other engines on the same level without any problems. Leela Net 323 is listet there with ELO 2651 at the moment which is a good result for the CPU-Version. Netx tests will be with engines around 2700.

Do either of you use the bmi engines?  They're a lot faster than the plain CPU ones.

I am afraid that my old Intel processor is not compatible with bmi Lela.exe. Anyway for those who are interested in running this version the link is : lczero10_mkl_bmi2_and_popcnt.zip
