I have a couple of systems that the CPU is liquid cooled and can handle full loads and not get noisy, but when the GPU's that they have in them kick in, (Not liquid cooled), they start to make some noise. I know I should have went with all liquid cooled and have learned my leason, but in the meantime. Anyway to stall the GPU's and let the CPU run wild?

Do you want boinc to ignore the GPU entirely or do you just want to not use the GPU at certain times?

It also depends on the GPU. A nice HIgh end GPU will produce more credit on Seti than a quad core. Since we can't see your Computers we can't tell what you have

I still want to use the GPU's, but the main computer I am talking about sits right next to my wifes computer and for her when she is at work it get to loud for her, so I have to pause all activity on that system while she is working. I would like the CPU to keep running but pause the GPU's, the fans are running about 70-80% and that gets to noisy in our office area. Any ideas? It is running quad core processor with 2 GTS250's. The other systems at work I have a handle on for right now, but the warmer temperatures of summer are comming, I hope, lol. Thanks for any help possible.

I'm not aware of any options on the client or the website that one can set to only use the GPU during certain hours. I believe you can only do that for both CPU and GPU at the same time.

However, you can set boinc not to use the GPU while the computer is in use, so you could have her move the mouse on the cruncher if the noise is bothering her.

A more high-tech and precise solution might be to write a script that keeps the computer active during the normal hours she is working, then lets the computer idle so the GPU comes back on at night. If you don't want to get into this sort of thing, you can just launch some kind of existing program that would make the computer seem active in the morning (either manually or scheduled by Windows, which I assume you're using), then manually quit it each night.

Any other ideas out there?

What is needed is an app that can be made to run when you want it to. And cease running when you want it to. Then add the app's name to your cc_config.xml file as an "exclusive_gpu_app", like this:

<cc_config>
<options>
<exclusive_gpu_app>sspipes.scr</exclusive_gpu_app>
</options>
</cc_config>

A built-in Windows screensaver ("3D Pipes") makes a nice 'test case'.

This setting tells BOINC.EXE to stop GPU processing when the named app is running. Use the name found in Task Manager's Processes tab, which may not be the same as the filename.

...and take a look at this thread: http://boinc.berkeley.edu/dev/forum_thread.php?id=6071 for more ideas / options (mostly command line stuff).

Ah, perfect, that is an option that will help. Weasel, add that option to your cc_config.xml file and specify a program that you will start when your wife is working and stop when she is done. She could do this manually, or you could schedule it to start and stop at certain hours.
