Drofa 1.0

[No4b]

With my own build I could increase the speed for my hardware by around 50%.

Code: Select all

g++ -Wall -std=c++11 -O3 -flto -pthread -mtune=generic -fno-exceptions -static -march=native src/*.cc -o drofa_10
(and fixing options.h like Gabor said)

Nps at depth 11 now 903.909.

Seems like your own windows compile is as fast as my Ubuntu one (in my Ubuntu tests Drofa is ~1.5-1.3 times slower than Vice)

Thank you all for helping me narrow down the issue to my compling. Before this i never used compilers, so i just didnt touch forked file. Seems i had a lot to learn about compiling options.

Started a gauntlet. Vice included, let's see I can confirm your claim.

Thank you very much! I hope my claim is legit, but i can never underestimate my own inattentiveness (for instance while testing king safety the first time i started test with a wrong book file, that contained like 4 openings). My main goal with vice 500 games match was to confirm stability, because before the final patch Drofa crushed once in ~200 games, so i didnt bother to output games into pgn, and now i cant confirm if test setup was proper.

Drofa_v.1.0 which file type is it ?

its a binary for *nix systems.
Works fine on my Ubuntu, but i cannot test it in other *nix enviroments.
