    Default OpenCL 1.1 Specification Released

    Phoronix: OpenCL 1.1 Specification Released

    The OpenCL 1.0 specification was released a year and a half ago, but now it has been superseded by the OpenCL 1.1 specification...

    Well, it's kind of sad that the OS drivers don't have support for it, but does it really matter, at least at the moment? I mean, is there really anything that take advantage of OpenCL? With OS drivers still not supporting OpenGL 3(nor 4), without good acceleration for video playback(at least not for my r700) and with rather poor performaces for those still without a working Gallivm3D driver(in particular after the KMS switch), IMO the OpenCL support should be at the very last position on the OS drivers' TODO list.

    I imagine there are a lot of people who'd like to tinker around with OpenCL programming without having to use a closed-source driver.

    Anyone know if there's a software fallback (i.e. OpenCL on the CPU) in case your GPU or drivers don't support it?

    Strongly disagree.
    Not even even everyone can take advantage of vdpau for example(my nvidia GTS 8800 cannot!!!), but anyone who has more or less descent video card could take major speed boost from implemented OpenCL, I can't wait to see implementation of it...

    Go to www.amd.com and download our Stream SDK. It provides OpenCL support for both CPU and GPU.

    I haven't tested CPU-based OpenCL with open source graphics drivers but it should work based on what I remember of the design.

    Can't support something that physically isn't there.

    That's closed-source as well though. I'd imagine that someone who refuses to use proprietary graphic-drivers to get OpenCL would also be reluctant to use a proprietary software-implementation.

    Agreed, but (a) I wasn't aware of any open source OpenCL-on-CPU implementations, and (b) at least this would allow chaos386 to stay with the open source graphics drivers (probably).

    Folding@home will soon be using OpenCL - see http://folding.typepad.com/news/2010...-or-later.html and http://folding.typepad.com/news/2010...st-update.html
