Rybka3 has more aggressive pruning than SF 1.7.

True, but only on lower depths, on higher depths (>20) situation gets the opposite. That's also the reason that gap between SF and Rybka reduces for larger depths in your testing.

I don't think this would happen, for several reasons:

I suspect Anand and Topalov wouldn't be so interested in an engine enough to want to hire someone to work on it.

What are they? Venture capitalists?

50 or 100 elo more and it costs this much?! Even in recent Amber (Blindfold + rapid) the total prize fund was only € 216,000. GM's have specifically indicated that the difference of 50 or even 100 elo between two engines wouldn't mean much to them because the engines are in >3200 bracket. They mainly use database of games and openings for their preparations.

Not the fault of Stockfish. A BSD *always* indicates a Windows or (more likely) driver or hardware problem.

And also for testing on long time control.

Tord and his silly understatements. I'm reading +80 ELO over 1.6.
The results seem to be especially good at single core testing, maybe helped by ponder on in Ingo's list.
I'm testing single-core ponder off. But I would suspect the Stockfish team does the same. So I'm puzzled they didn't see big improvement, unless they consider anything under 100 ELO negligible. Harhar!

Actually we didn't test against DS, mostly against 1.6 and sometime against R3.

I think it may be you, unfortunately.
I've been testing 1.7 against 1.63 (all x86 under XP, / Fritz 11) for ~8 hours now.
Well, I've done a fresh recovery disk install on my netbook, installed all the window updates. Stockfish 1.7 still doesn't work for me. As all previous versions have worked, I guess something critical must have changed. I'll have to try my luck with the next update
If you have an Atom procesor James, this might be something to do with detection of hyperthreading again? I fear there is no way to turn that off on a netbook? In Shredder Classic maybe you could type "ucidebug" which turns on the debugging function of the GUI and allows you to see which UCI commands are sent to and from the engine before it "dies". Alternatively you might turn on the log function in the UCI options, and maybe the programmers could learn something from a log file. Assuming the engine gets as far as making a logfile...

I'm just making a guess it has something to do with hyperthreading..

Eelco

I turned on the ucidebug and got this dump:

Hi Marco - I'd be happy to have a go if someone would explain what to do! But it's not something I've done before outside of "Basic4ppc".

If you have some experience with compilers you can download MSVC express (it is free):

http://www.microsoft.com/express/Downlo ... Visual-CPP

then from File->new->project from exsisting code

You could try to point to the SF sorces directory and let MSVC read the files, then compile (there is the corresponding menu).

I have to warn you that you _could_ waste some time in the effort, theoretically, once you have download and installed MSVC it is more or less a 2 minutes effort...but only if you have already done this before.

Hi Marco,

same problem here on my Quad Q6600, Win7 64bit.
Stockfish 1.7 only shows Threads=2 by default.
