Opencl support hardware requirements

I posted the below question here and below is the link: windows - OpenCL support hardware requirements - Super User

Do my machine support Opencl? I found this link ( Conformant Products - The Khronos Group Inc ) where the list contains the required hardware requirements. Please find the below screenshots of few of my machine. Does any one of the below support opencl?

Does any of my three machines support Opencl? Or all the three supports Opencl? I am trying to run a basic opencl face detection program and am failing. I have posted a question here regarding the same opencv - How to run basic OpenCL face detection code - Stack Overflow.

Install the latest driver and look for the openCL dll. If found, install the Intel OpenCL SDK, the NVidia Cuda Framework or the ATI Stream sdk and write a short program to test your capabilities. With Cuda you can see the openCL Caps with the NSight monitor.
