Re: Only 12% of my processing power is being used

All right, I'm convinced. Mostly. I still have both BOINC processes set to above normal priority, and my computer is responding fine. Are they really using all available CPU?

Two more small questions:

Would a 3D rendering program--rendering a single image for several hours-- not be completely filling the pipeline as well?

6.5 hours later, I have logged an additional 2 hours of time between the two projects I have running. I wasn't expecting for a full 6.5 hours, but I did hope for more. Is this typical?

Oh wait, and a third, since you're being so helpful. MsMpEng.exe. Is there any way to keep Windows Defender and not have this process occasionally go crazy and start using CPU and hard disk time? It's not doing a scan or anything. I just killed MsMpEng and Flash in Chrome, and that's sped up BOINC considerably. I think that might have been my problem all along (I'm still not satisfied with the math of the computation time-- 1 - 1/3 > 1/3, as far as I know--but I know my knowledge is limited).

Re: Only 12% of my processing power is being used

Should not. In fact BOINC 6.2.27 currently beta tested has options that can be controlled via the WCG device profile to set how many frames per second are allowed to use. Think it mentions that the rendering takes 5% of the CPU resource.

BOINC itself hardly uses time, it's the sciences that do that. Setting the processes high does not help, at least on windows it does not. Internally there's code to run it at low priority anyway.

But, my recommendation would be if not done already to start setting the Website device profile to Maximum Output to eliminate one possibility that BOINC is not taking all spare time available. Also, I'd disable all energy saving features in the hardware and OS. A tool I use called BOINCview lists out my quad at 98.7% efficiency i.e. the sciences are getting that much time per hour, per core.

Yes. Well, "completely" may be too strong. But if it is doing a lot of floating point mathematics, it is likely to use the pipeline a lot more efficiently than most programs.
