I have installed the driver and OCL-SDK on windows, but it only has headers and libraries. Is there some OpenCL examples I can use? For example, OpenCL program template, or some hello world examples.
There are a lot of OpenCL examples or sample codes available on the Internet. Once the OpenCL development setup is ready (i.e. required headers and libraries are available), most of those samples should work without any change (or with very little changes).
