Scatha and Glaurung 0.2.3

[Jim Ablett]

Hi Tord,

I've compiled an optimized 'Intel compiler' version - size 80kb.
Should run a bit faster, particularly on Intel machines.

Same download link. - includes MingW version too.

http://homepages.tesco.net/henry.ablett ... ng_023.rar

regards,
Jim.

[Peter Eizenhammer]

Many Thanks to Tord for the new version
and to Jim for compiling!

As Glaurung is a very important engine (imo) I always tried to find
the fastest compilation for my pc.
May I ask if there is a possibility that some of the major compiler gurus
(hm, maybe Dann, maybe Bryan, maybe ... ) give us their highly optimized
compilations to chose from? A version for Athlons would be a fine thing, for example.

Source, binary, build script, etc:

Binary only:
ftp://cap.connx.com/pub/chess-engines/n ... aurung.exe

The book does not appear to be changed to me.

Thank you very much, Dann!
That is extremely

Hello Dann,

I'm using Fritz 8 GUI, but I cannot load the Glaurung.exe as a UCI engine in the GUI; "Engine could not load" message.....

Thanks for your effort and of course Tord for this great engine.

Hello Dann,

I'm using Fritz 8 GUI, but I cannot load the Glaurung.exe as a UCI engine in the GUI; "Engine could not load" message.....

Hi John, it works here.
The glaurung.exe and the kpk.bin have to be in the same directory:
If you have downloaded the glaurung.zip from Danns server and unpacked
it correctly, this should be the case.

Thanks Peter, it works now with the KPK file, I can remember that in the past we always could download one .exe file without the KPK file ???

Is this correct ?

Greetings,

John.

The pawn tablebase is new, I think.

In easy.c and in root.c, extend() is called without the ks_delta arg.

E:\pgn\winboard-engines\scatha\src\easy.c(107): extend(move, &(ss->extension), &(ss->ext_reason), 0);
E:\pgn\winboard-engines\scatha\src\extend.c(11):int extend(move_t m, int *ext, int *reason, int mate_threat, int ks_delta) {
E:\pgn\winboard-engines\scatha\src\root.c(136): ext = extend(move, &(ss->extension), &(ss->ext_reason), 0);
E:\pgn\winboard-engines\scatha\src\search.c(233): ext = extend(move, &(ss->extension), &(ss->ext_reason), mate_threat,
E:\pgn\winboard-engines\scatha\src\scatha.h(573):extern int extend(move_t m, int *ext, int *reason, int mate_threat, int ks_delta);

I added an additional zero parameter to those two calls. You might want something different in there.

NO GUI though.

Jim and Dann: Thank you very much for the Windows executables! I will update my Glaurung page with binaries for all three platforms (Windows, Mac OS X, Linux) later this week.

John: You are right, the KPK bitbase is new in Glaurung 0.2.3. I forgot to mention it in my release notes.

Hi all,

I have now finally added binaries of Glaurung 0.2.3 at my home page. Thanks to Jim Ablett and Dann Corbit for helping me with the Windows version. I chose to use Dann Corbit's binary, because I assume it is a bit faster. Please correct me if I am wrong.

Scatha's GUI is now updated for Mac OS X 10.4.
