    I have been monitoring my resource usage while running my different boinc projects, and I've noticed that the einstein@home CUDA work units are only using around 10% of my total GPU. This is hugely wasteful, as I have other projects that will use 100% of my GPU power. Is this going to change in the future, or should I just change this to run on CPU only and use my GPU for more resourceful tasks?

      The initial ABP2 CUDA App will be essentially the same as the ABP1 one, i.e. it will just run the FFT on the GPU and the other calculations on the CPU. A custom kernel to bring these to the GPU, too is still being worked on.

      If there is a similar library to cuFFT for ATI one could use the same approach, but with the same drawback (lots of computation still done on the CPU).

      Currently it looks like we'll finish the CUDA kernel for ABP2, the port this to an OpenCL version that would support both GPUs (and then some computing devices).

        So yeah it pays to read all the stickys. Until they can get this project to make proper use of the GPU I think I will just run on CPU only and allocate my GPU power to more efficient projects.
