You do know yoyo@home is a cpu only project right? http://www.rechenkraft.net/yoyo/apps.php
Consider Collatz / Amicable Numberx or GPUGrid or moo, people talk many things in forum's so best to check the apps page.
Also I'm confused you said " send " , so are you not running boinc youself on your hardware and it's running at a school or business on someone else's hardware?
