poor folding performance on pentium M

hey folders. i have a pentium M laptop that i fold with, when it's on. it took FOREVER to complete a WU, it took about two hours per 1%. but i figured it was just a tough one. then, one of my opterons gets the same WU, and chews through the entire thing in 10 hours. now i know the pentium M 1.86 GHz wont be able to fold as quickly as the 2 GHz opteron, but still. it must have to do with the throttling down of the cpu speed to save battery life.

i guess my question is, how can i force the OS (suse 10.0) to use all of the cpu? it runs at 100%, but doesnt automatically throttle up, as it does when i use gimp, or any other cpu intensive task. it throttles down to 798 MHz, and folding suuuckksss. thanks for any replies.

My laptop throttles too as part of the centrino platform it inheritly uses speedstep to do so.. It's not hard to disable, generally speaking.

Right click on the desktop, goto properties, click on the screensaver tab, click the energy settings button, and switch the power mode in the drop down box to "always on" or "home desk/office" if "always on" isn't available, and restart. Assuming you're running Windoze XP, this should make the laptop stay at 100% throttle no matter what you're doing (not 100% usage, but like, disable clockspeed changes), mind you, "home office/desk" may still change how it does things according to if you're running off of battery or AC power, so for best result fold plugged-in.

He said he was using Suse 10, not Windows XP. Hmm, the only thing I can think of is an option in the BIOS...I'm not great with linux, I haven't used it in a while, so yeah.


 
well i can disable the throttling, but i'd rather not, i just want the folding client to behave like everything else, and step up the cpu when it needs to.

What's probably happening is that the process' priority is going low enough that Linux decides it's not important enough to leave the CPU at full speed. Try this:

renice 1 `pidof FahCore_7a.exe`

That'll make it a lot more important (default priority is 19, lowest possible is 19, highest is -20); if that doesn't make it bring the CPU up to speed try a lower (potentially negative) number. You could also play with the cpufreq tools, but I don't have a laptop so I haven't used them.

 
Just on an off chance.

Check how hot its getting.
Is it themal throttling.

Luck......... :D
 
i thought about the nice value after i posted. i will check it out next time i turn it on. thanks.
