Go up one level in this thread
yes, as I said, for shredder both graph is up (task manager--> CPU history) but for other engines such as uci engines, hiarcs etc, one graph is up and another is lower but not zero and cpu usage for them is not like shredder (100%). usually 50 to 60%. I did that test you mention and when I changed the nr. threads to 1 for deep shredder then it became like other engines and kn/s also became lower...So other engines possibly are not deep enough! any other comment appreciated it...thanks, bn On August 06, 2005 at 03:41:09, Rick Hagen wrote: >On August 06, 2005 at 03:21:11, Bahram Namjou wrote: > >>I am using P4 wxp with hyperthreading, and all of my engines are deep version . >>In case of shredder 9 (deep) display shows 100% usage and both line are in top; >>however in other engines, one graph is higher than the other with the total cpu >>usage of 50 to 60%.
