I have made an updated version of Chest 3.19 which I have called 3.19b with all the fixes on Heiner Maxen's homepage and compiled it for 32 and 64-bit execution, so if anybody is interested tell me.

Andreas
Interested.

Here is the link to the 7z-zipped file.
It is important to note that this is the console version of Chest and not the ChestUCI which also include these fixes in version ChestUCI 5.2
I hope this is OK by Heiner Marxen who has made this wonderful program.

Thanks Andreas!

I would be curious how big the difference between the 32bit and 64bit version is. Unfortunately I can't test it myself because I have no 64bit OS.
If someone with a 64bit-Windows would like to test this - create a batchfile Test.bat in the folder of the unzipped file of Andreas with the following lines (just copy&paste it from here):

Code: Select all

@echo off
cls
echo IE >Test
echo OE >>Test
echo F 1r5n/3N1p2/p2p1B2/4pkP1/7p/1R3BpK/1nP3Nb/8 w - - >>Test
echo z8w >>Test
echo jn >>Test
echo .. >>Test
echo Test 32bit ...
dchest32.exe <Test >32bit
echo Test 64bit ...
dchest64.exe <Test >64bit
echo Ready!
pause
Then just run Test.bat, wait 2-3 minutes and you'll have 2 files 32bit and 64bit. Look at the last line of both files and post the two times here please.

Regards,
Franz

Hello Franz,
I have get the following:
Time (real) = 75 sec (ca. 1.3 min) for 32 bits and
Time (real) = 77 sec (ca. 1.3 min) for 64 bits

Best.

Many thanks Ignacio!

That's indeed interesting, 64bit slower than 32bit???
So I would say it won't be very useful to make a 64bit version of WinChest (ChestUCI). :mrgreen:

Franz

From my tests there is almost no speed gain, but with the -M <megatbytes> option it is possible to use more memory for the hash table with the 64-bit compile I think.

Chest uses 64-bit entities in its calculation which could have been speeded up a lot, but because the program is designed for 32-bit it doesn't help just to recompile. I think Heiner Marxen himself or somebody with time to understand the inner workings of the program has to change it. If you understand the program I don't think it takes much more than some change in the way some elements are declared get significant speed gains from 64-bit execution. I have ported similar program from 32-bit to 64-bit and gotten a doubling of the speed.

That is all perfectly fine with me. :D

I'm happy that Chest is still a useful tool!

Cheers,
Heiner
