Stockfish 8 official

[mcostalba]

Stockfish 8 has been reelased few hours ago, you can download here:

https://stockfishchess.org/

This is the result of the effort of many people along many months: it has been a huge and hard effort and I would like to thank all the testers for their relentless patience, determination and creativity. I would like to thank all the people supporting us with CPU time (we don't ask nor accept donations so if you want to support us then donating CPU time through fishtest http://tests.stockfishchess.org/tests is the way to go and we greatly appreciate that). I would like to thank Kiran Panditrao for the super fast binaries provided in record time and Daylen Yang for the amazingly fast update of the site: you guys are great!

SF 8 is the same version that will go for the TCEC superfinal, it will be exactly the same, so what else should I say? Just finger crossed for TCEC and have fun you all with this new SF 8

The x64 popcount exe does not run on my AMD X6 1090t, and that CPU does have popcount support. The standard x64 exe does run.

The popcount exe does run on my AMD FX8350.

Thanks so much!
I have an i7 (2nd generation i7-2630QM) laptop. Which compile would work best for me?

The x64 popcount exe does not run on my AMD X6 1090t, and that CPU does have popcount support. The standard x64 exe does run.

The popcount exe does run on my AMD FX8350.

The Stockfish modern exe "Stockfish 301016 64 POPCNT" from ultimaiq.net does work on the X6 1090t and that I believe is exactly Stockfish 8. So I have a popcnt version of SF8 for the X6 now

On the FX8350 the above popcnt exe is almost exactly the same speed as the official POPCNT Stockfish 8 version.

Hi there,

at first, thanks to the SF team.
But I don't know which off all the versions I should test.

Here the results on my i7 5Gen. 4.0 Ghz PC.
ASM with a big "?"
BrainFish, SF 8 and the compile by ii u. ll is around the same!

Very fast machine Frank...

[Frank Quisinsky]

Hi Ray,

yes, and around 300.000 45-minutes games played (40 moves in 10 minutes) with the same hardware.

My list ended and I like to have the version in my list the SF team like to see.

I am absolutely not sure, should I test ASM or the official SF 8 because the differents to Brainfish or the compile by ii u. ll are small.

Best
Frank
