Is 100% CPU usage on folding using all of my core?

post #1 of 6
Thread Starter 
Since I can't run SMP due to the short days that it needs to be finished by, I run on 2 consoles at 100%. Note that I used to run on SMP at 100% as well.

When I am running at 100%, how come I do not lag and am able to burn DVDs and play intense game like Supreme Commander? I thought I'm suppose to get a BSOD or some major lag problems.

F@H only uses the CPU cycles you don't use. If it senses that you are using the computer, it scales back.

Well because FAH uses your IDLE CPU power.

Hah i can't play intense games while folding, but i fold with vmware linux SMP, so maybe that is why. It causes slight lag so i have to lower the priority.

Seriously? Wow. That's pretty cool.

Correct. So, when you are sleeping, and only 2% of your processor is being used, the remaining 98% is being used in F@H. However, when you are gaming and using 70% of your processor's power F@H only uses the left-over 30%.

The only impact folding has when gaming or running other intensive applicaitons is to hog some RAM as this does not scale back. Generally, it's not a major issue, though a few WUs do tie up a fair amount of RAM.
