Firebird 1.1 :

[jarkkop]

New silver suite(100 positions) 1min+1sec increment, Intel Q8400@3.2GHz

One core for Rybka
Four cores for Firebird

I thought that they were both using one, but Firebird had massive edge in calculation power.

1 FireBird_11_w32_ms_k : 2493 100 (+ 54,= 41,- 5), 74.5 %

Rybka 3 w32 : 100 (+ 54,= 41,- 5), 74.5 %

2 Rybka 3 w32 : 2307 100 (+ 5,= 41,- 54), 25.5 %

FireBird_11_w32_ms_k : 100 (+ 5,= 41,- 54), 25.5 %

Yes,I do agree....
Extremely aggressive and strong chess engine....
In my tournaments it's scoring around 80% against the top 50 in my rating list....Even Ruffian or Rybka didn't have such a performance in their best days....

Firebird and all the Ivanhoe/Iggorit/whatever variants crash on occasion. The SMP implementation lacks something to be desired.

Why does rybka get one core and firebird get 4? Whats the point?

Don't know about the others Dann,but FireBird works fine here under my Windows 7 x64 Ultimate and using the Arena 2.0.1 & ChessBase GUI particulary Fritz 11 GUI....

I have had quite a few crashes.
I think it is a function of duration and thread count, with longer searches and greater thread counts resulting in more crashes. If you run low thread counts and fast games or analysis, then it won't be much of a bother.

Hi Jarkkop, I wonder why do u faced FB 4 CPU vs Rybka 3 1 CPU?? is clear that the result that you have is "normal" and don´t say anything about improvments in FB 1.1, as far as I know Norman Said that the only diference between FB 1.01 and 1.1 is that FB 1.1 can upload robbobases, nothing about changes in search neither function eval . Honestly ,theres is not big diferences in elos among IPPO family, Igorrit, Robbo, FB , Ivanhoe have almost the same elo, more o less, the only thing that change in each version is fix buggs and "cosmetics" improvments, i don´t see changes in eval or search...., so I wonder if this engine could jump + 50 elos in a near future, but i could be wrong about this statments

Regards

Accident, I did not remember to check the the default thread count for the Firebird.
I thought it was one core vs. one core. It was just after the test run I noticed this.

PS. Actually I had already send the original mail and just noticed my error just after that and edited the mail, because canceling the post is not possible.

More even result when equal HW, one core for each, same silver suite

Accident, I did not remember to check the the default thread count for the Firebird.

I dowloaded it yesterday. The default number of threads was 16.
Shall it be adjusted to the processor numbers on PC ?
Theoreticly 1 SP can support 16 threads by sharing time mechanism.
