Tornado 6.0 released

[Engin]

Ok, but the version without SSE is a little bit slower then with SSE, because the SSE version is using the faster PopCount function.

however if it stops again or you found something other bug, let me know.

[Damir]

You were right Engin. My hardware does not support SSE. The other link works fine even though it is a little bit slower. There is no more crashes.

Thanks Engin

What is the estimated Elo gain over the 4.88 version

well, that's difficult to say, because its depends on wich version, wich time control, how much cores are using, how much games playing, pondering or not, and of course on wich hardware you running it.

a quick test match Tornado 6.0 x64 SSE vs Tornado 4.88 x64 SSE on my own hardware (AMD Phenom II x6 1090) with shredder classic GUI, 3+2 sec. time control with ponder, i noticed after 100 games a improvement around +80 elo.

on different time controls, games and hardwares that can be change. i don't have the time to testing intensive.

Wow,even at this time control that's an amazing improvement

Thanks again Engin and good luck with further releases....

I think the distinction is not between SSE and non-SSE but rather between SSE and SSE4.2 (or something like that).

Yes, you are right. More precisely, SSE instruction sets and the POPCNT hardware instruction are separate things. The only thing we can say in general is that SSE4.2 implies POPCNT. But the reverse is not true: there are some AMD machines with SSE3 only but with POPCNT support.

That is why, SF "modern" compiles use SSE3+POPCNT, but not SSE4.2

[Modern Times]

there are some AMD machines with SSE3 only but with POPCNT support.

Indeed, the Phenom II X6 is one example

That is why, SF "modern" compiles use SSE3+POPCNT, but not SSE4.2

Given that I have one of the above CPUs, thanks to the SF team for understanding this situation. Some authors just provide SSE4,2 as a high-end compile, and of course they don't work on the X6.

?? ok, one match only vs. one opponent only and a "family"-match...

-44 to 5.0beta after 600 games and still -14 to 4.88

5 matches played on:
- AMD-FX 6300 @ 3,5GHZ (5 cores used, 1 core free for OS etc.)
- Classic GUI (started 5 times on the X6)
- 40 moves/3 minutes repeated

1 match played on:
- Intel Core i5-540 (notebook) @ 2,53GHZ
- Arena 3.0 GUI
- 40 moves/3 minutes repeated

Thanks ++, Engin. A complete rewrite sounds like a lot of work...

Much appreciated,
