My laptop has ATI Radeon 4500 graphics card and Intel(R) Core(TM)2 Duo CPU P8700 2.53GHz as CPU. When I query OpenCL for platforms the Output is like this:
Found 2 Platforms
==================Platform No 0======================

and when I query for opencl devices the output is like this

I think something is wrong. Because in the Platform ID 0 which belongs to graphics card there is two devices. One for AMD(ATI) and another for Intel. But in Platform ID 1 which belongs to Intel CPU there is only one device. I have installed both AMD APP and Intel OpenCL library. I can see this output in AMD Codex software and I'm sure about the output of the code. Why does ATI(AMD) Graphics card show two devices while I have two core in the CPU. I'm so confused. please help. thank you
