Hi
As I mentioned earlier, I have gotten the Device implementation working under Linux (Bart, I have not yet had a look at the win32 CMakeList changes) and commited the changes. I have also posted some initial benchmarks on my wiki page.
From the benchmarks it can be seen that the memory transfer overhead is the major contributor, but the CUDA plugin still manages to kill the CPU implementation (on my ageing 3500+ at least) by a factor 20x or more in many of the cases considered. I would like to improve the benchmark system though - so I think that will be my nexy step - although the other image processing plugins should be a breeze now. Once the benchmark system is up to scratch, then the users out there with different hardware can start making submissions so that we can get a nice idea of the landscape.
Evan
