I'll make sure that it's Gaviota 0.86.

You have to keep an eye on Graham

Graham,

I see that DiscoCheck's games haven't started yet. Is it possible to update it ?
https://github.com/lucasart/chess/tree/master/bin
The Windows 64-bit compile (with hardware popcount) is discocheck_4.0.3.exe

I'm not sure if your i5 CPU has hardware popcount. Anyway, the only way to check if the compile works for you is to open a command line, cd into the directory where you put the compile, and run:

Code: Select all

discocheck_4.0.3.exe bench 12

At the end, it should say

Code: Select all

signature = 6727896

I've tested it with Wine 1.5 64-bit under Linux, and it worked. I cannot be 100% sure that it works with the real Windows, but it's very likely.

[lucasart]

After doing a bit of research, it appears that most CPUs do not have hardware popcount support (only the *very* recent ones). So I also did a compile for CPUs that do not have hardware popcount.

A little test to verify the compiles, and compare performance:

Linux 64-bit compile, hardware popcount

Code: Select all

$ ./bin/discocheck_4.0.3 bench 12
signature = 6727896
time = 4.07829

Windows 64-bit, hardware popcount: OK (using Wine)

Code: Select all

$ wine bin/discocheck_4.0.3.exe bench 12
signature = 6727896
time = 4.41089

Windows 64-bit, no hardware popcount: OK (using Wine)

Code: Select all

$ wine bin/discocheck_4.0.3_nopopcnt.exe bench 12
signature = 6727896
time = 4.74528

PS: When no hardware support is available for popcount, GCC generates code for it that is not the most efficient. I can beat the compiler by making two different versions of a SWAR popcount, and having a complicated makefile (like Stockfish), but I'm way too lazy to do that

I'll update to DiscoCheck 4.0.3 and yes, my i5 does support popcount.
