Can you add option to not run CPU versions of applications for which GPU versions are available?
I want to focus my cpu on N-Body Simulation and run Separation on gpu..

That can be achieved by setting up a second location preference. For instance, the default setting can run GPU work, and you could set up, let's say work location, to do CPU work. That's how I do it. To do this, go to project preferences. Under the edit preferences link there are buttons to add separate preferences for home, work, and school. After you get a setting for the non-default preferences, go to your account page and click on the "computers on this account" link. Now looking at your list of computers, on the left hand side is a link for details, click on that. At the bottom there is a location drop-down menu. Select your location and then click the update location button. Hope that helps :)

Will there be gpu version of n-bodyapplication?

I believe Tom stated they are working on developing an n-body gpu app currently.

But that requires two PCs. I don't think you can exclude them on a single PC with a single location.
That would be useful, though I think BOINC has scheduling/priority problems when you try to run both CPU and GPU work units on the same PC anyway.

Yes Boinc does have problems cpu and gpu scheduling and yes you can run both on the same pc with fewer problems...load up a 2nd copy of Boinc in a different directory and run one for cpu tasks and one for gpu tasks. It's not as easy as it sounds but not that difficult either.

I finally got around to doing it. I have done it before when needed, and it does work fine, at least on Linux.

I think that is the hard way though. The project could provide that option I would think.
I doubt that very many people will do the double instances of BOINC trick. It is a bit involved the first time.
