To my surprise I just when to check the current standing in TCEC and was shocked by the performance of the young little cute Girl Alliestein

And this was an earlier version of Alliestein Vs Houdini ==>
Never thought that Alliestein was in the same level with LCZero and Stockfish !

Even more shocking are the two crashes of Stockfish due to a faulty file.
One more crash and it's out.
The participant authors took a vote on whether or not the SF people should be allowed to replace that file. but because one voted no, it won't happen.

After many tests this is really a surprise.

Offhand not sure - something to do with the compiler I think. They were discussing it in TCEC chat.corres wrote: ↑Fri Sep 13, 2019 11:06 amWhich file of Stockfish was faulty?Graham Banks wrote: ↑Fri Sep 13, 2019 3:39 am Even more shocking are the two crashes of Stockfish due to a faulty file.

They used a compiler and optimization options different from the regular builds to make the binary a little faster. Unfortunately a library used by this build is buggy and causes a deadlock sometimes.

The faulty file was a Windows dynamic library file: libwinpthread-1.dll. Due to insufficient testing and insufficient attention to prior bug reports, this buggy file was part of the package sent to TCEC by the Stockfish "team". The file itself is not part of the Stockfish code. At least, this is my understanding. So one more crash/hang by Stockfish and the engine is disqualified.corres wrote: ↑Fri Sep 13, 2019 11:06 amWhich file of Stockfish was faulty?Graham Banks wrote: ↑Fri Sep 13, 2019 3:39 am Even more shocking are the two crashes of Stockfish due to a faulty file.

I did not know the official Stockfish use such .dll.
When I tried it I got very few speed up, if any.

That is ridiculous. Tcec is a computer chess fan driven site. Let's ask them!!!Graham Banks wrote: ↑Fri Sep 13, 2019 3:39 am Even more shocking are the two crashes of Stockfish due to a faulty file.

Yes, it was my impression too that Windows and OS/2 was designed to use DLL not to improve speed, but to save disk space. The intention was that similar API (libraries) inside the DLL file can be reused by most applications, hence saving small disk space.corres wrote: ↑Fri Sep 13, 2019 1:18 pmThanks.zullil wrote: ↑Fri Sep 13, 2019 12:16 pmThe faulty file was a Windows dynamic library file: libwinpthread-1.dll.

Sorry, I am not claiming I am technically better than those SF programmers, but building a binary with additional DLL is _not_ optimum, in my opinion.

Re: Never thought that Alliestein was in the same level with LCZero and Stockfish !
My understanding is that there is no real speed increase from using the linked library. But using it allows the MingW compiler to carry out LTO (link-time optimization), which does seem to give a good speed boost (at least on some systems, not mine).corres wrote: ↑Fri Sep 13, 2019 1:18 pmThanks.zullil wrote: ↑Fri Sep 13, 2019 12:16 pmThe faulty file was a Windows dynamic library file: libwinpthread-1.dll.
