I have 2 GPUs - I'm wanting to fully utilize the secondary GPU (GPU2) for crunching, leaving the primary GPU (GPU1) for the Desktop/Gaming/etc.

Is this possible, if so - how?

Use the <ignore_cuda_dev>X</ignore_cuda_dev> flag in cc_config.xml.

Devices are numbered from zero onwards, so if the second GPU is the one you want to have ignored you add:

<cc_config>
<options>
<ignore_cuda_dev>1</ignore_cuda_dev>
</options>
</cc_config>


Save into your BOINC Data directory, then exit BOINC completely (so not just the Manager) and restart it. This can't be used with re-reading the config file.
