AMD Catalyst 12.6 Beta Driver

With the release of the AMD Catalyst™ 12.6 Beta driver (“Catalyst”), AMD would also like to announce that we are moving away from our Monthly Catalyst release plan. Our goal is to ensure that every Catalyst release delivers a substantial benefit to our end users; as we have today with the release of the Catalyst 12.6a Beta. We will still continue with the Catalyst naming convention; Catalyst: Year.Month. You just won’t see a new driver every single month.  We are confident that this will only benefit the end user; you’ll only need to upgrade to a new Catalyst driver, when it makes sense.

We would also like to announce the introduction of our new AMD Issue Reporting Form. We made a number of improvements to the older Catalyst Crew Feedback form, making it more comprehensive, ensuring high quality feedback. Feedback is very important in every product company’s life, especially in our fast paced environment. This is not just a check-box for us – we take these reports very seriously.  We will review every report posted here and investigate every issue encountered. Please use this form whenever you encounter something worth mentioning.

Catalyst 8.98 exposes 1 new OpenGL extension.

It also teases the Geforce R305 driver branch (unless the screenshot with 2 different version numbers was photoshopped).

The very latest driver on this planet is a mobile driver and from Toshiba, miracles do happen.

Like 302.59 from CUDA5 preview this driver exposes 6 new OpenGL extensions, i'm too lazy to look them up though.
Also this driver works worse with AMD's LEO demo.

Thanks for the info, looks like Intel pulled 2712 from their servers? You can get it still here.

AMD updated their site: some samples have now OpenCL 1.2 infos

They screwed up some links: if you catch an old sample, change the path like this

AMD APP SDK 2.7 supports development of applications using the OpenCL Specification v 1.2. As all OpenCL 1.1 APIs are Zupported within OpenCL 1.2, you also can develop OpenCL 1.1-compliant applications.

For SDK 2.7, the following values are returned when querying strings from OpenCL:

                          CL_PLATFORM_VERSION: OpenCL 1.2 AMD-APP (build.revision)
                          CL_PLATFORM_NAME: AMD Accelerated Parallel Processing
                          CL_PLATFORM_VENDOR: Advanced Micro Devices, Inc.

                      •   Check the Platform Vendor string, not the Platform Name, to determine AMD hardware. For
                          example code that shows how to check and use the CL_PLATFORM_VENDOR string, see the
                         AMD APP v2 Samples.

Supported Devices

What's New in Version 2.5

    Support for AMD APP SDK v2.7.
    Support for OpenCL™ 1.2.
    Support for collecting performance counters on APU devices.
    Full support for profiling with AMD Radeon™ HD7000 series GPUs based on Graphics Core Next/Southern Islands:
        Added support for kernel occupancy analysis.
        Added support for collecting performance counters for DirectCompute (DirectX 11) applications.
        Addition of SALUBusy counter.
        Fixed value reported for VALUBusy counter.
        The values reported for LDSFetchInsts and LDSWriteInsts counters were inaccurate on AMD Radeon™ HD7000 series GPUs; thus for those GPUs, those two counters have been replaced by a single LDSInsts counter.
        Fixed display of kernel ISA.
    Improved OpenCL™ analysis module:
        Added detection of deprecated OpenCL™ APIs.
    Added support for showing source and destination location, as well as zero-copy status for memory transfers initiated using clEnqueueMapBuffer or clEnqueueMapImage. This information is displayed in the API Trace view.
    Added support for Microsoft® Visual Studio® projects that use User-defined Macros in the project settings.
    Fixed the --workingdirectory (-w) command line switch (set current directory) on Linux.
    Fixed some problems with importing previously-generated profile results into Microsoft® Visual Studio®.
    Changed the default installation directory on Windows to %PROGRAMFILES(X86)%\AMD\AMD APP Profiler to make it more consistent with other AMD tools (i.e gDEBugger and CodeAnalyst)

Imagination makes the case for mobile OpenCL

Imagination was showing off GPU compute on a cell phone chip at GDC, physics in your pocket. If you think that upcoming GPUs will allow this to be reality, it was running on a current TI OMAP 4430 chip.

The idea is the same one that everyone is talking about, offload certain functions from a CPU to a GPU to speed them up and possibly save some energy while doing so. In a desktop, CPU power is in abundance, and power use is not really a big concern. While laptops are a little more energy conscious, anything that will tax a laptop CPU for long time periods will probably be done while plugged in. This means that GPU compute and OpenCL are used mainly to address problems that CPUs are really bad at, or just take a long time.

MandelMark is an Android application that has been developed by ZiiLABS to measure the floating point performance of modern mobile processors by visualising the solutions to the Mandelbrot set using an OpenGL ES 2.0 shader program. ...
MandelMark Explained

    Two triangles are drawn on the screen and an OpenGL 2.0 shader is used to render the MandelBrot set
    For each pixel the shader program is called to calculate the colour value of the pixel
    The shader loops up to 255 times to calculate if the pixel is within the Mandlebrot set
    The colour of the pixel is based on the number of loops taken to confirm it lies outside the set, or black if it lies within it
    The shader defaults to 32-bit floating point for the rendering if available
