Stockfish 1.6.3

[zullil]

It may (or may not) be interesting to see whether a combination of portable compiler flags implied by -fast can give a significant speedup. You should be able to find out what these flags are by comparing the output of g++ -O3 -Q --help=optimizers and g++ -fast -Q --help=optimizers.

Having once done this, I recall that it wasn't interesting (to me).

From the man pages:

Code: Select all

On Intel target, -fast currently enables the following optimization
           flags:

           -O3 -fomit-frame-pointer -fstrict-aliasing
           -momit-leaf-frame-pointer -fno-tree-pre -falign-loops

           All choices of flags enabled by -fast are subject to change without
           notice.

[Thomas Cutter]

Code: Select all

- Add hardware POPCNT support for gcc: use 'make gcc-popcnt' to enable hardware POPCNT support if you have an i7 / i5 CPU

Because you stress i7/i5. AMD Phenom supports POPCNT as well. Does Stockfish only support the Intel-way of POPCNT?


Kind regards Thomas

Anyone knows how to make this work under Ubuntu+Scid? I'm a Linux noob

Unpack the JA build (see this thread) to get an optimized executable.

[Damir]

Bravo, you won on time in a completely lost position...

[Nimzovik]

A win is a win.

[Damir]

Yes, and a BS game is a BS game. There is no need to post them....

[IWB]

A win is a win.

True, but he should write that he wins with with PREMOVE (and maybe some LAG), so with a GUI feature the enigne does not have and can't influence ... He will NEVER repeat that live on an observed computer without premove.

The day Chessbase switches off premove in the engine room is the day we do not see games from him anymore!

In short the title should be, (as always): Father's fast finger: 1, Chessbase GUI (+ WWW): 0!

In other wods: His wins are tecnical wins, but never on the board!

Bye
Ingo

[Nimzovik]

Hmmmm....... some of your assertions are assumed. Note also a time win is a win. That is why they have clocks at tournements ....yes? I fail to see the need for the animosity. His win does not take anything away from the engine or the maniacal fans of the engine. It is simply pride of accomplishment. Relax! The game does not necessarily prove anything. His style (as evidenced by many other games) of play -the stonewall - is really quite astute and fair in taking liberty with the machines rather blatant -shall we say -pernicious (?) - handling of positonal concepts. His style does indeed makes itself felt. Why not? Why not capitalize on the machines fallacious er....thinking? Should the human play the way a machine wants (needs ) it to play to fit some peoples definition of chess? Do not the machines take advantage of a human's fatigue and other factors? Ahmmmmmm? Perhaps Pablo is to the machines as Steinitiz was to the death of the 'Romantic' style of chess.
