Title: CPU Bouncing Up and Down
Post by: Fleexy on July 20, 2010, 01:03:33 PM
While running F@h, my CPU usage graph resembles this:

I'm just wondering if this is normal.

It looks like the spamz0r "Watch full free movies online" is posting in every board >:(

What are yoor system specifications?
At a guess, it looks like you're running the single core client on a multi core CPU, which will give about 50% CPU usage and each core will "bounce" up and down.

I'm not sure how many cores I have (I think 1) but you might want to know that that was only the top of my graph that I took a screenshot of.  The low is around 65%.

Top half?

Precisely.

Precisely.

if you have two "halves" then you probably have two processors, unless I am misinterpreting you.

My bad, I meant I only took a screenshot of the top of the graph.  Now my CPU is stuck at 100%:

(that time I took a screenshot of the entire CPU graph area)

as far as i know your cpu will work at 100% as folding is using the spare left after the pc uses what it needs

Correct, (in my multi cpu core version anyway - smp2 v7.1.24). The software is configured for 100% cpu usage by default (recommemded), and the 'FahCore priority' is configured for 'lowest possible' by default (recommended). This way f@h does not consume resources when other funtions require them.

 The 'Percent CPU usage' and 'FahCore proirity' can be set in the f@h software client configuration control panel by clicking configure tab/advanced tab, but the default setting normally should not present any problem with other funtions. I would only suggest occasional monitoring of cpu temps to ensure they are within max safe range for your particular application. Also more frequent maintenance may be required, such as blowing dust out of the cpu heatsink because the cpu cooling fan will likely be running at high speed more consistantly running the cpu @ 100%.

I know this post is about a month late, but did you get your F@H software running okay?
I hope so. If not please post to this thread again.  ;)

OOP's. Sorry about that. I guess I could have looked at the post date year or his stat's a little closer.
 Just trying to help.  :)
Thanks BC!
I hope Fleexy comes back and trys F@H again.
