    Default AMD Releases OpenCL ATI GPU Support For Linux

    Phoronix: AMD Releases OpenCL ATI GPU Support For Linux

    AMD has released the fourth beta of the ATI Stream SDK 2.0, which provides a complete OpenCL development platform with OpenCL ATI GPU support for the ATI Radeon HD 4000/5000 series. Besides running OpenCL on the GPU, this ATI SDK also supports running OpenCL on SSE3-capable, multi-core CPUs from both AMD and Intel too...

    Awesome. Go ATI ;-) Now we just need a video acceleration :>

    Looking at
    http://developer.amd.com/GPU/ATISTRE...s/default.aspx

    Integrated GPU's are not supported. Is that because they are not meant for heavy work load, and would therefore over heat?

    Or does these lack some hardware features, so not even the open source version of OpenCL would support integrated GPU's?

    Of course OpenCL makes the most sense of high end cards =)

    Reading the released specs of NVidia's G300, there is "native support for execution of C++ on GPU." That means running "real C++ applications" on the GPU. Does ATI allow that too now with OpenCL or is this something entirely different?

    lol

    Yes, it's something different entirely. Something called vapourware.

    Nvidia fakes Fermi boards at GPU Technology Conference
    http://www.semiaccurate.com/2009/10/...mi-boards-gtc/

    I looked at the presentation from NV's website, and I really question the "proof" that Fermi exists. It looks very much like a pre rendered animation they are playing, where they have dropped some of the frames in "the slow one".

    Update 3 in the article backs up the theory, that those just were pre rendered and mock ups as well

    The OpenCL code only supports HD4xxx and higher GPUs. The IGP parts all use cores from earlier generations.

    I believe the issue is the on-chip LDS/GDS memory blocks which allow data sharing between GPU threads. Those blocks first appeared in the HD4xxx family.

    Interesting stuff.

    So does that mean that there will be no forthcoming support for the HD2xxx and HD3xxx families? If so, that makes me want to cry...
