Out of curiosity:

I was wonder since there is a option to "Use at most N % of the CPUs" is there a way to limit a single cpu core to a certain project only and in another project have another core dedicated to that one? I noticed it uses all the cores if allowed but it places the tasks in a core it generally pleases.

Also could you do the same with GPU's I have a second system gonna be up and going soon and I would like to limit each gpu to a certain project so for instance one project doesn't happen to take over both but only use the one while the other project can get work when available to use on the other specified gpu.

Enlighten and ideas?

BOINC doesn't support CPU affinity. You can however tell BOINC to run at most X tasks concurrently for any project. How the tasks are distributed among available cores is up to the OS. See <max_concurrent> in Application configuration.

This can be done with <exclude_gpu> in client configuration (same page).
