Your welcome.

You can start here( http://developer.amd.com/tools-and-sdks/opencl-zone/opencl-resources/introductory-tutorial-to-opencl/ ) for basic understanding on OpenCL terminology. 

I understand that specification sheets can be daunting, but if you are interested definitely look at Sections 2 &amp; 3 at chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/https://www.khronos.org/registry/cl/specs/opencl-1.1.pdf . That has the best explanation of what OpenCL is and what it can do.

I have a repository where i add examples whenever i have time. You can look into them at https://github.com/9prady9/CLGLInterop , but these are specific to OpenCL-OpenGL interoperability. You can always google for example code :)

Regards,
Pradeep.
