Re: Chess.com 2018 computer chess championship

[ That jump assumes that all engines have NUMA support. It is my understanding that only Stockfish, Houdini, Texel, and Ethereal have such support. I'm tempted to add Komodo into that too, based on some chats with Mark, but I don't know that first hand. The key to decent NUMA support is to have eac...

Re: Lazy SMP and 44 cores

In Wasp, I start all threads at depth=1 and let them do their own ID loop. At the start of each iteration beyond 6 (I think) I count the number of threads already searching this depth or higher and if the count is more than 50-67% of the total (I'm not sure what is best) then the thread will skip to...

Re: CEGT - rating lists June 03rd 2018

Hi Werner,

On the 40/20 rating list I see a line for Wasp 3.0 and one for Wasp 3.00. Should these be combined?

Thanks,

John

Re: Experiments and curiosities

Hi Ed! I get similar results when running fixed depth matches between Wasp3 and Stockfish 8. Wasp wins 96% against SF at depth=4 :) depth wins draws losses 1 306 271 423 44.15% 2 707 68 225 74.10% 3 915 54 31 94.20% 4 956 8 36 96.00% 5 922 57 21 95.05% 6 885 83 32 92.65% 7 884 95 21 93.15% 8 764 143...
