    Help newbie here. the current display drivers does not support opencl for the graphics card.

      Not able to run the sample code in GPU.

      I have been installing like 10 times today different versions of ATI catalyst. I have windows 7 ATI Mobility Radeon HD 5470. Downloaded 11-2_mobility_vista_win7_32-64_ccc.exe and  ati-stream-sdk-v2.3-vista-win7-64.exe files from download section of amd website and installed on my system.

      I tried running the CAL sample file FindNumDevices and CLinfo. I am getting

      Supported CAL Runtime Version: 1.3.185
      Found CAL Runtime Version: 1.4.519
      Use -? for help
      CAL initialized.
      Finding out number of devices :-

      These are the outputs that I m getting from running these samples. I have been struggling with this for a long time and couldnt find any document relating to this.

      Any help in making the sample code in GPU will be greatly appreciated.

      Thanks

          nou

          that CAL version is somehow low. i have with 11.1 CAL version 1.4.900. and certain version of SDK need certain version of CAL or higher. (IIRC SDK 2.3 need catalyst 10.11 and that have CAL version around 1.4.700-800) but maybe mobility versioning is different.

            Your driver installed properly as FindNumDevices reports one device found.

            Could you please run following CAL sample and past output here?

                     NLM_Denoise_Compute.exe -e

            Could you please run following OpenCL sample and past output here?

                     Reduction.exe -e -q
