Hi,

Where is the OpenCL SDK for Mali GPUs if available, and when will it be if not?

Many thanks,
Tim

    Hi Tim,

    The OpenCL SDK is in the final stages of release and should be available at malideveloper.com within the next few weeks.

    Thanks,
    Chris

    Where can I get your OpenCL offline compiler ?  Thanks

    Also,  how do I run OpenCL on an android system or development board like arndale (Exynos 5250) that has Android ?

    Hi Mitch,

    We do not currently provide an offline kernel compiler at this time.

    For Android platforms, OpenCL is not currently available via the SDK, so you would need to use RenderScript for this purpose.

    Please let me know if you have any further questions or need any clarification.

    Thanks,
    Chris

    Hi,
    Is it workable to use OpenCL SDK via  the Android NDK? And Anroid SDK call function which is OpenCL implemented via JNI interface?

    I am using Exynos 5250 with their custom Andorid build (jb-mr1, basedon Android 4.2).  It does have libGLES_mali.so under /vendor/lib/egl. 

    Someone on Exynos5 forum said he can run the OpenCL applications (clinfo). I downloaded his binary and it does run !

    However,  when I use ARM OpenCL SDK.   I tried the sample/sobel,  it does not run.  The Android gives the following:
      # ./sobel
       sh: ./sobel : No such file or directory

    It looks like the ./sobel isn't valid binary for Android.

    When will OpenCL support be available on Android ?
    Since It works for Linux, where can I get the linux that has the driver for OpenCL ?

    Hi Mitch,

    ARM's OpenCL SDK only targets Linux platforms such as the Exynos-based Arndale development platform.

    We have not created a Renderscript Compute SDK for Android devices.

    Hi Pete,

    Where can I get the binary (or source if available) of linux that runs on Exynos-based Arndale ?  The one on arndaleboard.org site does not have drivers for OpenCL.

    Thanks
    Mitch

    Hi Mitch,

    ARM are currently working closely with a few select ecosystem partner companies using the Arndale board and a binary build of the OpenCL drivers. The hope is to extend this soon so the wider public can get access to these binary drivers, but this is not available yet.

    There will be an announcement once the software is more widely available to alert developers (including those following these forums).

    Cheers, Pete

    Dear Pete,

    If I understand correctly:

    a) OpenCL applications cannot be used on Arndale with Linux installation beacuse the openCL drivers for Arndale(Linux) are not yet available to the public?

    b.  It is possible to use openCL on Android running on Arndale as suggested in the thread below, using headers from Mali SDK?

    c) I am not clear, on which board and platform can I develop an application using Mali SDK. Can you suggest one?

    Your answer will be really helpful.

    Best Regards
    Manu

    Hi Manu,

    A) Unfortunately ARM does not control if or when API drivers are made available by the silicon vendor, we supply the core RTL and the driver source code as part of the licence agreement to our licencees. If a particular API driver is not forthcoming, you should lobby either Samsung or Insignal in this case to provide those drivers to you. We (ARM) do provide a build of Linux containing the OpenCL driver to select partners under a specific license, but this is not public at this time.

    C) The only board I am aware of currently with T600 silicon is the Arndale board. It is the responsibility of either Samsung or Insignal to make binary drivers available for this platform.

    Hope this helps.
