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 http://stackoverflow.com/questions/17475003/how-to-run-basic-opencl-face-detection-code.

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.
