Subject: Re: Re: JtR CUDA ????

OpenCL is for Nvidia and ATI, but CUDA is only supported on Nvidia chipsets.  As CUDA is more hardware specific, it is generally 2-4 times faster over the same OpenCL implementation.  Since OpenCL is so new, I expect we will see performance improvements as it develops.  From what I have seen, you can expect CUDA to migrate to be fully compatible with OpenCL while maintaining backward support for older versions of CUDA.  OpenCL is the future for now.
