New Poll Regarding GPU Application of N-Body

I think you are confused. There is no N-body gpu app so no N-body gpu code.

I'm afraid you are confused this time, there is an n-Body GPU application, but it was never released as it needs same time on the GPU as the CPU application on CPU while separation is 50-60 times faster on GPU than on CPU. See the first message of this thread. Releasing this application as is would slow down the overall throughput of the project.

Exactly the reason why N body application does not have a GPU version

On top of not making a bit of sense to even have it around, what's the point if it's not as efficient as the current cpu app, they already have a gpu app here so don't NEED to release a slow inefficient one.

Of course to speed up n-Body processing they could offer the possibility to not "Run CPU versions of applications for which GPU versions are available" and credits similar to Separation would surely help too, right now when crunching n-Body one might get the impression, it isn't very valuable type of work considering the "pay" we get for it. ;-)

I agree the credits aren't up to par and several Admins have said they will look at it but they always come back 'we're happy where they are' which isn't helpful at all for those doing the actual crunching.
