    JeremyL

      Hello

      i would use many HD5870 card under my RedHat linux 5.3 for GPGPU compute.

      I have installed ati-opencl-beta-driver-v2.0-beta4-lnx and ati-stream-sdk-v2.0-beta4-lnx64.

      i have 4  hd5870 and 1 monitor under each

      i make a aticonfig --adapter=all --initial for configure it.
      my Xorg.conf is attached

      when i start my Xserver , i have the badge "AMD Testing Use  only" in right-bottom of each monitor

      in the amdcccle, i have 4 screen

      for the command :

      aticonfig --list-adapters
      * 0. 13:00.0 ATI Radeon HD 5800 Series
        1. 0c:00.0 ATI Radeon HD 5800 Series
        2. 8d:00.0 ATI Radeon HD 5800 Series
        3. 86:00.0 ATI Radeon HD 5800 Series

      * - Default adapter

       

      but when i run FindNumDevices, i have

      $./FindNumDevices
      Supported CAL Runtime Version: 1.3.185
      Found CAL Runtime Version: 1.4.467
      Use -? for help
      CAL initialized.
      Finding out number of devices :-
      Device Count = 1
      CAL shutdown successful.

      Press enter to exit...

      for lspci i have :

      $ /sbin/lspci | grep VGA
