I'd like to limit the exclusive gpu app to just certain GPUs. I have one GPU I always want BOINC to run on, while the other I use for games. I edit <ignore_nvidia_dev> every time I want to play a game without disabling all GPUs. Is there a better way to go about this? I didn't catch it if it was in the configuration or FAQ.

You can use the tag in cc_config.xml



Don't use the given GPU for the given project. If is not specified, exclude all GPUs of the given type. is required if your computer has more than one type of GPU; otherwise it can be omitted. specifies the short name of an application (i.e. the element within the element in client_state.xml). If specified, only tasks for that app are excluded. You may include multiple elements. 


<exclude_gpu>
   <url>project_URL</url>
   [<device_num>N</device_num>]
   [<type>nvidia|ati</type>]
   [<app>appname</app>]
</exclude_gpu>


e.g.
<exclude_gpu>
   <url>http://albert.phys.uwm.edu</url>
   <device_num>0</device_num>
   <type>ati</type>
   <app>einsteinbinary_BRP4</app>
</exclude_gpu>

The above will tell the first ATI GPU in the system (device 0 = first device) to ignore the Albert project their OpenCL application. You can use multiple excludes per file.

I've used <exclude_gpu> at some point to limit what project apps a certain GPU should be allowed to run. I don't want to exclude a GPU from a project or one of their specific apps or use by BOINC in general. Can I specify the GPUs <exclusive_gpu_app> configuration applies to?

No, all the tags in cc_config.xml are for all or nowt. The only way to do what you want is to switch between two cc_config.xml files.

No need to request it either, as the developers are looking into ways to make the whole of BOINC easier to use, not more difficult.
