Cfish 9 is OUT!

[syzygy]

Looks like you'll need to compile for yourself.

No longer!

What to do with makefile in order to compile it?

Assuming you have a compiler and (the utility named) make installed (and have some idea what you're doing )

Type

make help

and read about the options.

It compiled with the original makefile without problem for TDM-GCC directly out of the 'box' Here is a BMI2 Windows compile. Ah, I see Ronald has provided his own compiles now.

Do you know if we can build one for MacOS?
I just tried running "make build ARCH=x86-64-modern" (like I do for the master Stockfish) but I'm getting:

<...>
In file included from benchmark.c:30:
In file included from ./settings.h:4:
./numa.h:7:10: error: 'numa.h' file not found with <angled> include; use "quotes" instead
#include <numa.h>
^~~~~~~~
"numa.h"
1 error generated.
make[1]: *** [benchmark.o] Error 1
make: *** [build] Error 2

I see there's a Linux binary so I was hoping we could get one for MacOS

I compared the speed of cfish_9_x64_modern_windows.exe
provided in
https://github.com/syzygy1/Cfish/releases/tag/cfish_9

with the speed of stockfish_9_x64_popcnt.exe
provided in my contribution candidates for the official Stockfish release:
www.zipproth.de/Brainfish/SF9_Windows.zip

Surprisingly, the Stockfish compile seems to be clearly faster.
I never did this comparison till now and expected CFish to be faster, perhaps someone can cross check this.

Also SF9 bmi is 10% faster than Cfish bmi. Some other benefits ? I tested in corei5 and windows.

On Linux/Wine on my Sandy Bridge i7-3930K, the Cfish binary is faster.

On Linux/Wine on my Kaby Lake i7-7560U laptop, Cfish is again faster. Same for the bmi2 versions.

How are you measuring? Default bench?

You could try "make build ARCH=x86-64-modern numa=no".

I have recompiled the binaries with -flto. Not much faster on my system, but maybe it helps on other systems.

Yes, Default bench, here are the results:

cfish_9_x64_bmi2_windows.exe:

Total time (ms) : 1873
Nodes searched : 5023629
Nodes/second : 2682129

stockfish_9_x64_bmi2.exe

Core I7 3770k 3.5GHz Sandy Bridge Windows 7:

[syzygy]

On my old Sandy Bridge laptop with Windows 10:

stockfish_9_x64_popcnt.exe: 1737077 nodes/second
cfish_9_x64_modern_windows.exe: 1805761 nodes/second

Compiled with gcc-7.2.0 (and without -mnative to avoid unwanted dependencies).

Interestingly, Cfish compiled on my old Windows laptop (with gcc-6.2.0) achieves 1879397 nodes/second.
