Toga's node search in mp-mode

Post by Denis P. Mendoza » Sat Apr 19, 2008 2:41 am

Since Toga is open source and still under dvelopment at the moment, I'd like to ask external experts on their views about toga's case concerning it's node-search from single to 2-core. I've done a simple 10-sec epd test for the following engines:
Rybka 2.2 32bit
Rybka 2.2 64bit
Rybka 2.2 32bit MP 2-core
Rybka 2.2 64bit MP 2-core
Toga 1.4.1SE single and 2-core
Toga 1.4.2JD single and 2-core
Toga 1.4 beta 5c single and 2-core
Toga 1.4 beta4a single and 2-core
test position:

Code: Select all

8/6p1/P1b1pp2/2p1p3/1k4P1/3PP3/1PK5/5B2 w - - 0 1 bm Bg2;
The log results are here:

Observing and comparing results between Rybka and Toga. Toga's 2-core node-search is just as similar with what a 64-bit Rybka is doing. Is this the limitation of a 'Shared Hash' multithreading? Any suggestions or comments?

Can you post a summary? I'm not willing to go thru a half-dozen attempts to popup windows on my machine, wait for adds to display to download, etc...
