To use only one GPU and not the other, you can use several options:
1. BOINC uses only the best GPU by default, so if you have two different GPUs, and you do not force the , only the best GPU will be used. BOINC decides what's the better GPU based on a) compute capability; b) software version; c) available memory; d) speed.
You see those when BOINC does the detecting of the GPUs.
If both GPUs are the same brand and model and have the same detection arguments, they'll be used both automatically.
2. You can force BOINC to ignore one or both GPUs, using the client configuration option of , or , depending on what brand GPUs you have.
An example of such a cc_config.xml file:
0
3
The above ignores ATI GPU0 and Nvidia GPU3.
3. You can exclude certain GPUs from being used on this project. To do so, use the client configuration option of
The above will exclude the use of Nvidia GPU3 from being used on the Einstein project in combination with the BRP5 GPU application. You can do this for multiple applications.
4. To use no GPU at all, make a client configuration file and add into it:
1
The above will stop BOINC from trying to detect a GPU when it starts up.
To activate any of the options above, does require a full exit & restart of the client.

To use both, make a cc_config.xml file in your data directory and add into it:
