So... now be so kind to explain how a NUMA patch could possibly give 10% more speed on a non-NUMA machine.
"In the windows version large pages is off by default,"
Code: Select all
o["Large Pages"] << Option(false, on_large_pages);
"so any speed increase of brainfish
(when not enabling large pages) is due to the better/different compile."
So to paraphrase your own statement, in Cfish large pages are on by default. So all the benefit of Cfish over SF is due to large pages. The rest is just trivial translate that brings virtually nothing.
About 8.5% on Windows without LP (ignoring the 2% I backported to SF). I have only tested on Sandybridge though.
And then you laugh at Brainfish guys for changing the name
I have no right to say anything but YOU do? Heh. What have you ever done... apart from trolling this forum?
Anyway, taking 99.9% of SF code and replacing the names of the authors with your own is a bit questionable, yes. And it may have been the reason that people like you have gotten this strange idea that brainfish contains innovations beyond the Cerebellum book code.
and in the same time use print_engine_info with 0 argument. How pathetic.
Oh wow, you have read a single line in main.c.
I understand now that you are not a programmer at all.
What a horrible, sneering post !
I didn't know this Forum is only meant for Programmers ; News to me.
As if anyone who isn't a Programmer is just plain stupid.
FYI there are other Professions apart from Programming which also require a high degree of Intelligence.
Have you considered that computer chess may just be a Hobby for many people here and we can't spend as much time as we would like on it, as many of us earn a Living through other Professions ?
You call that guy a Troll. People like you actually provoke Trolling.
In fact, its a moot point who really is the Troll here.
I find most of your Posts obnoxious, sneering and condescending.
You may be a brilliant Programmer but your Behavior and Attitude negates that. I feel you're basically not a nice person.
You richly deserve all the Trolling you get, and more.
