    SubDevices on AMD HD5850

    Ragnar78

      Hello everybody !

       

      In the stardards, the following is said concerning the return value of clCreateSubDevices, when applied to my HD5850 graphic card.

       

      "CL_INVALID_VALUE if values specified in properties are not valid or if values specified in properties are valid but not supported by the device. "

       

      This is what my program returns when I try to partition my HD5850.
      I tried several partition schemes but all ended up on that same return value... Creating a list with one device of 10 compute unit does not work eit

       

      Replacing in my code CL_DEVICE_TYPE_GPU by CL_DEVICE_TYPE_CPU, I can partition my CPU accross all the possible schemes.

       

      Therefore, I was wondering if the HD5850 was partitionable or if i was more likely to have a buf in my implementation ( which would be surprising, considering it works fine for the CPU.)

       

      Thanks !
