Hello

I have a problem. It refuses to use 100% of my CPU. Whenever core 1 reaches 100% it bumps core 2 down to 95-100%. Then core 2 goes back up to 100% and we have a loop.



According to Boincstats the client version is 5.10.45. Is the client the core client or the GUI? I use Ubuntu 8.04 with an AMD Athlon X2 4200+. I have set it to never use more than 100.00% of my CPU while idle or active.

Do you still want your operating system to do anything? Do you want to be able to move your mouse, tap a key on your keyboard, see anything on the monitor? Do you want things to be written to disk?

If you do all of that, then you'll know why the science applications that run under BOINC won't use 100% of all your cores. They allow other things to happen on your computer as well. If any of them went for a higher priority setting and taking all your cores 100% of the time, nothing else would be able to run, including BOINC.

Why is it BOINC in Windows uses 100%?

Why is it BOINC in Windows uses 100%?

It doesn't. On XP C2D, CPU usage by Boinc and the Science app is around 99% when when the computer is idle. When torrent software and Media player are running about 97%. It can drop to as low as 88% when some my other applications happen to be running. Even lower when playing my games. That's the way it is meant to work.

BOINC itself will only use the maximum amount of CPU when it is doing benchmarks. At all other times it uses about 1% a day. The science applications that you get from the projects you attach to are the ones that use the CPU. But even then they use it at the lowest possible priority in the operating system. This means that anything else that needs the CPU at a higher priority will take the CPU.

Anything else is all the hardware you have in your computer that is sending interrupts around, the operating system you have on it that is sending interrupts and remote procedure calls to check up on hardware, etc. etc.

So you are saying I only use 90-100% CPU perhaps because of my memory? I am used to the applications always using 100%, but at the lowest priority so it did not have to monnitor how much is used constantly and do work according to that, but rather use all available and not leave a single percent unused.

No, it's not because of the memory! I think what we all want to say is:
It's not a bug, it's a feature. It works as designed.

Computer sind nicht alles im Leben. (Kleiner Scherz)

If BOINC + apps aren't at 100%, then look at what else IS using processor time.

Sorry, I don't expect BOINC to use 100%. I just expect the total CPU use to be 100%. I am used to that with Folding@Home - it will always use ALL the remaining CPU resources.
