Re: Doom for Commercial Chess Softaware Unless...

....unless they can give to us a phenomenal better GUI and services package. With monster like robolito and others of the same class, who need a new Shredder or even Hiarcs, for God sake? But of course if you give a very strong engine -even if it is not the strongest- AND a package full of frills, ...

Re: Stockfish at the top

Looks like the quality of play improves with time faster, than for other engines. I wonder how good human-free Stockfish 1.7.1 is at correspondence chess.

I'd like to see CCRL for 40/40 Intel i940 and not 40/40 Atlon X2 4600+.

Re: World Chess Championship

I know that engines are bad at openings, but I analyzed the position just before the Qd6 novelty with Stockfish. [D] r1bq1r2/p4pkp/1p4p1/n7/3pP3/3B4/P2QNPPP/2R2RK1 b - - 1 16 At depth 28 with 4 PVs Bb7 = -0.28 Qd6 = 0.00 Re8 = 0.00 Kg8 = 0.00 Probably Bb7 is the best move, it was played in Karjakin,...

Re: Stockfish at the top

http://www.computerchess.org.uk/ccrl/4040.live/rating_list_all.html Why is F.... not mentioned? Great news. The engines that should not be named are very strong at short time controls while losing strength at long time control, I guess in 40/40 Stockfish is unconditionally the best. Some guys on ot...

Someone would need to lead the initiative and dish out the positions though.
Same here. (I have Q9300)

Re: Stockfish 1.7 and benefit of hyperthreading?

I tried stockfish-17 bench 4 2 10 against stockfish-17 bench 4 1 10 and 2 threads on one core consistently give lover time to depth in all positions in the test. Milos if you are so sure I suggest that we play a match between 1 thread and 2 thread SF1.7 on N280. I'm ready to bet 50$ that after 1000 ...

Re: Stockfish 1.7 and benefit of hyperthreading?

.... I wonder what kind of instructions are executed by chess engines the most. There is only one execution unit. So these two instructions are executed in the same place. Computationally intensive operations (like chess) occupy the whole execution unit, and it is completely irrelevant to how many ...

Re: Stockfish 1.7 and benefit of hyperthreading?

From wikipedia: When execution resources would not be used by the current task in a processor without hyper-threading, and especially when the processor is stalled, a hyper-threading equipped processor can use those execution resources to execute another scheduled task. (The processor may stall due ...

Stockfish 1.7 and benefit of hyperthreading?

I realized that on my N280 netbook Stockfish gets almost 50% more nodes per second if I set it to two threads. N280 is single core processor with HT. People here and on Rybka forums said that nothing is gained by using more threads than actual CPU cores. Is it a common misconception or just somethin...
