I just can't seem to get it to work with fedora...At least not version 5. And when is the cuda forum going to be opened again? Cuda is really cool!

Executive summary: With CUDA, the code became much cleaner, and it run 15 times faster (1500% speedup!)

Get a modern Nvidia GPU (200 series) \’cause running with 8000 series is not that fast.
bad:
memory limitations
debugging could be painful
only single precision is fast (double precision is slower than CPU)
