I agree. I have never seen Sean Evans contribute anything useful. He is the very definition of troll. Moderators, please...

Interesting stuff. Thanks User923005 and Hyatt for your informative replies.


2. DB was different from others of today in terms of the singular extension idea. Nobody does it like Hsu did. Too expensive and too complex. One only has to read his paper to see all the tricks they had to employ ...

I ran that position for a only a few minutes this morning with Stockfish 2.3.1 ...

Ahhh, yeah, that was the position, thanks for showing that. Now that I see it again and run it, I can see that you are right. This seems easy for modern machines, and therefore reasonably within reach by Deep Blue. Wasn't there a 2nd position in the game that bothered him as well, a pawn capture on ...

Anything you say can and will be used against you :twisted:
I will immediately admit that most of the above is nitpicking on something terribly unimportant. But of course I had to take the last word he gave me, so that he could take it back again :D

Anyway, I think it is interesting that Bob's ...

I DO change my opinion when I discover something new or expose a mistake in my reasoning. You act like that is abnormal.

Yes, this is what I expected to hear about the OS. What is still unclear to me is the number of threads the OP set Houdini to use. If he set 4, then I assume that the OS would run each thread on its own physical core, regardless of whether or not hyperthreading were enabled.

You are correct that ...

I think you may be seeing a speed up because by manually setting the processor affinity you are essentially taking ...
