By right clicking BOINC tray I can switch off GPU usage temporalily (which is basically allowed in BOINC's options). But after a while BOINC switches GPU usage on automatically (without any action by myself). This is annoying when watching video on the computer since these two tasks get in conflict with each other and the only way to clear the situation is shutting down the computer (which means the loss of computing results of the last hour or more).

How can I make sure BOINC is obeying my temporary GPU restriction up to my explicit switching it on again? Do I have to change some options somewhere?

Thank you for hints.

Sorry, I forgot to say I'm using BOINC 6.12.34 on Windows XP SP3.

The 'snooze' option lasts an hour. This cannot be changed.
What you need however, is the <exclusive_gpu_app/> option in cc_config.xml, with which you can set that BOINC should suspend using the GPU, whenever the program you specified, is running.

Used as follows:

<cc_config>
<options>
<exclusive_gpu_app>Notepad.exe<exclusive_gpu_app>
<exclusive_gpu_app>winamp.exe</exclusive_gpu_app>
</options>
</cc_config>

The above will suspend using the GPU whenever Winamp or Notepad run, and stay that way for as long as either program stays in memory.

There's also a CPU switch, <exclusive_app/> which can be used in much the same way, only difference here is that this will suspend all of BOINC when the program you specified runs.

Check the link to the cc_config.xml file for more information.
For more examples, see this BOINC FAQ.

Boinc only suspends CPU or GPU usage for an hour when suspending usage via the tray icon,
Eithier suspend GPU usage via the activity menu, or use the <exclusive_gpu_app> option to suspend GPU usage when a particular app runs:

Thank you, Jord and Claggy,

the exclusive_gpu_app option is exactly what I was looking for.
