testing R4 against Fire 1.31 on 8 cpu at 4+2

[Dr.Wael Deeb]

All in all,it seems like Rybka 4 is stronger than Fire 1.31....But Houdini is a different story indeed....
Dr.D

On big hardware like this, R4 is definitely stronger than Fire, and I'd guess, Houdini. On littler hardware it is much different.

Peter

Agreed Peter....it looks like on octal machines things are a little bit different....if we assume that Rybka 4 is a dumped version of the cluster Rybka,then there is nothing more to say....the scaling on the bigger hardware will show the difference....

have not checked new Houdini.

Fire 1.3 scaling is quite good.

[George Tsavdaris]

here is a game where Fire thinks its fine and Rybka says mate in 39.

Interesting. Thanks for the game(s).

[Gino Figlio]

Wow, in that time control (240+2) the difference is huge. Have you tried faster tc's in your hardware?

[NATIONAL12]

no,i just wanted to show how good R4 was.i only play corr so even this time control did not mean much to me.take it from me R4 is very strong and a great engine to use in corr games to help you out.

[NATIONAL12]

perhaps Norman would like to chip in

Huh, I thought it was still the crappy Iggorit SMP code. Norm must have changed in behind my back .

yes ..clearly Rybka 4 is far superior to Fire...!?
you can't actually see me (without a webcam) but: i'm actually on the floor...prostrating myself in complete humbleness to you and Rybka 4's Octal magnificence!

you were right all along Paul...!
nobody will ever again doubt your incredible chess engine genius!

with that said, i humbly beg forgiveness....
Rybka 4 is awesome !!!
clearly much stronger than anything else!
(Paul Watson's testing guarantees it!)

buy it today!
(how much is it)?

PS-
pehaps if you contact Vas with these results and an indication of your dedicated and fervent fanatacism...you and he can become frends!?
