    Didn't AMD, nVidia, Intel agree to deprecate CUDA and Close To Metal?
    CUDA is the architecture. C, Fortran, OpenCL, DX11 Compute, etc. are all programming languages that run on top of CUDA.

    nVidia: the company whose cans are still closed even after being opened.

    Actually Nvidia has been promoting openCL as well since it's introduction from apple (in fact they were the ones that worked closely with apple to develop it).

    Nope, they just agreed to have a unified cross platform solution as well. Much like openGL and DirectX. DirectX is windows only but OGL covers all OS's and support for both is strong from the hardware manufacturers.

    BTW intel is also working on their own proprietary solution as well for larabee.

Cuda offers a solution for programmers who prefer to code but not having to worry about items such as memory management, the C compiler handles that for Cuda and it also serves as a foundation for other API's such as openCL, Fortran, C++, Java, DX11, etc. openCL offers a lower level API which sometimes is more desirable for development but you also have to do things like manage your own memory which can add to code complexity. With openCL support added they can appease both preference of coding.

    Now I understand what you meant my 10 characters limit

    One of the reasons OpenCL is so attractive is that it gives a general purpose solution for speeding up typical desktop operations as well :
    How do you as a developer decide if you want to use the CPU or the GPU for a task? Trail and error, and hope that the test is representative?

    So it is about graphics and video then

    I think the word you are looking for is "license" and not "steal"

    It's called middle ware, and it is a great business for Cell developers at this generation of consoles, as the PS3 is so difficult to develop for.

    Middle ware solutions also had a boom with Sega Saturn, as it also had many different processors, and generally a pain to develop for.

    Middle ware ease the (game) developers work.

    OpenAL is an example for open source middle ware.

    Unreal 3 engine is an example of closed source middle ware.

    ??

    darned 10 character limit

    EDIT -- just to be clear when I said "make use of existing closed source code" I meant "make use of OUR existing closed source code, eg things like the shader compiler".
