My ATI FirePro V4800-based QuadCore desktop is running the Collatz Conjecture very quickly on the GPU but relatively slowly on the CPU. Because I value more highly some of the biological research platformed on BOINC, I would prefer to run Collatz on the GPU only, while simultaneously (not switched) running a project like Rosetta@home on the CPU cores, as Rosetta does not run on this GPU.

This appears to be an odd-enough formulation that BOINC is not geared to it. Is my understanding of the situation correct?

Just go to your Collatz Preferences and set use CPU to No:

[pre] Use CPU No
(enforced by 6.10+ clients)[/pre]

You have four differerent venues (at each project) so you can set different sets of computers to do different combinations of work.

Thank you for your suggestions. I understand the restriction of Collatz to the GPU only, and I will add the Rosetta application. The reason for the question is that the BOINC 'preferences' offers 'minutes between switching applications', from which I inferred (probably erroneously) that applications would not run simultaneously, but only back-to-back so to speak.

Worked a charm. Thank you!
