Rybka3, Arena & Hashtable szie

[Robert Weck]

Hi Robert,

I am using an Intel Core 2 Duo CPU, 2.20 GHz. I don't think it is a slow cpu....

i did not especially mean you, i was only opposing to Oliver's statement, that "more is always better"

You don't need a 500 HP car for driving through Manhattan (or Singapore )


best regards,
Robert

For short, the evidence isn't enough.

...Of course you can use 512 MB for HT, but in my eyes its only a waste of memory, if you do games with less than 5 mins/move!

Nevertheless i only wanted to point out, that i doubt, that the statement "more is always better" is really true!

OK, the example that user said, 2GB, (the diferents in seconds...) the differences are too scandalous for not keeping them in mind...

If we have enough RAM for system, and for "ANALYSIS game, ( test one position, to analysis only that move... more ram always is better, for that purpose... and but it is this way, it is an error-superBUG, then the programming of the engine, not this taking advantage of the ram correctly, being optimized alone to have good results in the constant game, fast game, or engine versus engine,... but those optimizations have a pernicious effect in the slow analysis of a game....

if the correct move is found early then small HTs should perform better.
on analisys game ? it´s false. only in super fast game... 1 min / all game.

Have you ever checked, how long it takes to fill hash tables?
Here i have a notebook with a Pentium M 1,7 GHz and 512 MB; with Toga 3.1.2 it takes around 2 mins to fill just 128 MB.
too much for super fast games...

Of course, with that comment your, you don't make more that to reaffirm that it is a scandal that doesn't take advantage the ram correctly.

if the ram is filled and empties so quick in fast computers, then to that lost fellow man of seconds comes ... ???

P.S.: not so long ago, i read a posting in a forum (i don't remember which forum it was, sorry; maybe the german CSS-forum?) who did various tests and got also better results with 128 than with 256 or 512 MB...

in the distant times of fritz 5,32, they wre said that with a cpu of 200 MMX, X took time in filling the hast-table, and they only indicated that doesn't use a lot of ram in very quick games. BUT NEVER to analyze with a lot of available time ...

The example of this case is a nonsense and if it assures it to him a programmer, THIS lying.. of course...

For short, the evidence isn't enough.

It is another form of saying:

let us run a dense veil, and that nobody doesn't find out.

For ME, the evidence is enough... VERY enough...

PD: thanks for Kah Huat, Koh, Gerd Lahnstein etc...

It´s a SUPER BUG
