    Can only see half the device memory as global memory using OpenCL

      Hi,

      System: AMD Phenom(tm) II X6, 2 x AMD Radeon HD 6990, Ubuntu 11.10, Catalyst 11.9, AMD-APP-SDK-v2.5



      The two GPU devices show up as four OpenCL devices, which is OK, but they only have 1GB of global memory each. Each device has 2x2GB. How do I get access to it all?

          It is expected to show four devices as X2 cards are considered as two separate devices.

           

          Full avaiable memory is not supported yet. It will be available in future releases.
