SmarThink 1.98 is out

[Werner]

Thanks Sergei,
I will use the standalone AVX2 version for my tests;
although the other AVX2 version shows a bit different output lines and kns.

[Sergei S. Markoff]

Wow, it's strange.
Do you have values.txt in engine folder?

[Sergei S. Markoff]

Thanks Sergei,
I will use the standalone AVX2 version for my tests;
although the other AVX2 version shows a bit different output lines and kns.

I've just tried every of executable and nodes count is exactly the same for the same depth. NPS of course differs because AVX2 is the fastest compile.

Hi Sergei,
thanks for the answer. Both engines are in the same folder. I installed both inside the Shredder GUI, load both and press analyze.
Here nps and Rating differ a bit.

May be it's because of some hashtable data from previous search?

;
Maybe, the differences between these 2 compiles have been really small:

SmarThink_v198_x64_AVX2.exe 273.920 01.02.2018 11:53 -a--
SmarThink_v198_x64_AVX2_standalone.exe 355.328 01.02.2018 11:51 -a--
I see it in other positions too - but I think it is not worth to spend a lot of time to find out the reason. I was only a bit wondering why. Maybe the compiler options or the downloaded Intel64 redist. make such differences here.

I hope for good testing results.
best wishes

The only one that runs is the "normal" one without any special instructions, but very slow.
It looks to be some kind of bug or error in the detection routine, maybe it's geared towards Intel processors and not AMD.

I will have to use the "normal" version for my tournament for the time being.
