    Question Opencl or CUDA

    Hello

    Im in a projectgroup, where we need some heavy graphic calculation to be done.
    The main project-idea is based on CUDA, BUT some of us don't got a nvidia gfx card within our computer. So..

    How ready is opencl and do both nvidia and fglrx support opencl today? I do have the option to borrow a computer with a nvidia card, but could we just use opencl instead?

    OpenCL on nvidia is well documented and thier drivers are complete but are not publicly available yet (you have to be a registered developer to get them right now).

    OpenCL on AMD is so far just on the CPU. No GPU yet (as far as linux is concerned). To get their openCL libraries for the CPU you also have to be a registered developer.

    intel of course is MIA and S3(Via) is rumored to having theirs close to completion for their Chrome 5 series cards.

    BTW openCL runs on CUDA. Too many people think CUDA and C for CUDA are the same thing, they are not.
