Frank-Walter & Tablebases

Post by AdminX » Fri Sep 27, 2019 1:36 pm

I am not seeing TBHits when using Frank-Walter 2.4.0, is there a problem with my settings? My OS is Windows. The JSyzygy.dll file is in the default engine directory, I also placed a copy in the Java / Lib folder. I am using the Shredder GUI.

Code: Select all

Program=java -jar -Xms150m -Xmx1024m frankwalter.jar -cores 4 -tt 256 -tb D:\SyzygyBases\DTZ_7;D:\SyzygyBases\DTZ_6;D:\SyzygyBases\DTZ_345;D:\SyzygyBases\WDL_7;D:\SyzygyBases\WDL_6;D:\SyzygyBases\WDL_345 
Thanks in advance.

Thanks in advance.
I am not sure if FrankWalter (name was changed lately from Frank-Walter to FrankWalter BTW),
1. supports 7 men at all
2. multiple syzygy directories

The readme etc. doesn't mention multiple folders at least
http://computer-chess.org/doku.php?id=c ... lter:index

I only have 5 men syzygy here and the log says FrankWalter loads them.
TB hits is something else though and it ios possible your Shredder GUI cannot show TB hits for a xboard program.
You should just confirm if any log says syzygy bases are loaded.
Edit: forgot to mention that the easiest way for you would be to add the -debug flag for confirming

BTW default is 256MB anyway but you need to specify mb or gb in xour cmd after the number (readme)

Code: Select all

CommandLine := Java -jar frankwalter240.jar -debug -nobook -tt 512mb -tb C:\Syzygy_5 -cores 1

FrankWalter doesn't send the tbhit information. The output that it sends only contain ply, score, time, nodes and PV, and not the extended information for selective depth, search speed and tbhits.

Hi Tony, note that his pic not even shows loading of the syzygy bases, just the dll.

Okay, thanks for the replies. The info provided is good to know. I think the problem may be multiple syzygy directories.

Okay so I have confirmed it does not like multiple directories and give an output of 'NULL'. Thanks for the -Debug tip. I hope an update will address this issue.
