CPU usage limit not working right

post #1 of 14
Thread Starter 
Hi there,
I moved my folding client at work to a different computer yesterday and decided to set the CPU usage to a percentage lower than 100% because it slowed my performance in a visible manner.
I set it to 80% and my CPU usage is at 20% rather than 80%. If I set the value to 100 in the client.cfg file, my actual CPU usage sits at 25%. Looked to me like it divided the value in the config file by 4, so I set it to 300 or 400, but that didn't work either.
So now I'm confused. I want it to use 80% of my CPU at all times. The new computer is a Core i5 2400, no GPU.

Here's my config file:
[settings]
username=Shub
team=37726
passkey=<removed>
asknet=no
machineid=1
bigpackets=big

[http]
active=no
host=localhost
port=8080
usereg=no

[core]
cpuusage=80
checkpoint=30
addr=

[clienttype]
type=3

Are you using -smp 4 tags? Do you have HT on or off?

It's a Core i5 2400, so no Hyper-Threading
As for -smp 4 tags, not sure what you're referring to. You mean an additional argument to the command line used to start the service? I set the client as a service so it runs when I'm not logged in. I know where to go to change it, I just wasn't aware that I had to.

Yeah the cpuusage does nothing in the config. You need to limit the number of cores the client uses. Just add the -smp x argument where "x" is the number of cores you want the client to use.

Ah, I thought this was on your 930. And yes, you have to have the -smp 4 arguments. You can create a shortcut, add the arguments, and then move the shortcut to the Startup directory. That way it'll startup on boot-up with -smp 4 on.

I don't want to use the Startup folder since that only works when I'm logged in. The computer is on 24/7 but I log off at the end of the day, so I need the folding client to run as a service. Logging off would otherwise terminate the process.
I just modified the command line and it is now as follows:
C:\\Folding\\FAH6.34-win32-SMP.exe -smp 4 -svcstart -d "C:\\Folding"
I just restarted the service and my CPU usage is at 25% still.

Once you finish the current WU, it'll start using 100%.

Alternatively, you can erase the queue.dat file and work folder to get a new WU.

Indeed I am now using 100%. But now I'm back to my original problem, which is that I wanted to use 80%, not 100%. Can nothing be done about that, it's either all or nothing?
post #10 of 14
You can do -smp 3 to use 3 cores, which will be 75%. It'll spread 3-cores' worth of load across all four cores.
