Crafty 25.1 Release

[Gregory Owett]

I'll post one in a little while.
I made one yesterday, but it was not from the official released sources.

Thanks a lot, Dann !

[Gregory Owett]

Many open source developers just release a source code, there are several good reasons why they do so. The "roll-eyes-smiley" is definetely out of place here.

[Dann Corbit]

Crafty is open source.
So anyone can make a UCI adapter for it to create a UCI crafty.

My crafty.rc file:

Code: Select all

mt 10
st 5
smpnice=1
egtb
tbpath=C:\chess\syzygy;J:\Syzygy;G:\Syzygy;
hash=1024M
hashp=64M
ponder off
learn 0
book off
log=off
swindle off
exit

When I start Crafty:

Code: Select all

F:\project\dcorbit\crafty-25.1>crafty
EPD Kit revision date: 1996.04.21
unable to open book file [./books.bin].

Initializing multiple threads.
System is SMP, not NUMA.
max threads set to 10.
search time set to 5.00.
SMP terminate extra threads when idle.
SYZYGY EGTB access enabled, 6 piece TBs found
hash table memory = 1G bytes (64M entries).
pawn hash table memory = 48M bytes (2M entries).
pondering disabled.
book learning disabled
book file disabled.


Crafty v25.1 (10 threads)

Thanks,
Now it works perfect here!

Hi Dann!
Should there be an .exe within

Hi, I found the .exe
But the .exe works only on modern CPUs (Skylake, Ivy Bridge) not Bloomfield like my i7 920.

It works on my AMD FX8350 which is not that modern.

This is the reason I stopped trying to distribute executables 15+ years ago. Too many operating systems / versions, too many different architectural platforms, too many different compilers, too many different GUIs, and so forth, multiply all of those together and you get a LOT of combinations to try to support. Easier to distribute source and let users type "make" and then execute the thing.

Thanks Dann. When I compile here with GCC 5.4 on Windows using your settings I get quite a few warnings:

They are just warnings though, and it seems to run OK.

The comments in the Makefile say to try options to find out which gives the fastest compile. Does Crafty have a Bench command to allow a speed test? Or is there some other way to accurately compare two compiles?

Thanks!

[Dann Corbit]

Crafty has a bench command.
For me, I get a faster binary with no profile than with a profile.
So I usually just run make.
But you can run the make file with:

make -j windows-gcc-profile
and then run make and it will use the gcda file.

The make file automatically chooses the hardware you build on for the instruction set, so you don't have to change architecture.

What changes are needed to your makefile to compile and run on 32-bit Windows 7 using gcc?

Thanks.
