Hi Sajjadul, As I said I don't know what is going amiss in your code. Debugging this type of thing really requires a proper overview of all the code and ideally testable code. This level of support is something I can provide.
Perhaps if you can't manage the wiring up of OpenCL and the OSG yourself you should look for 3rd party example codes that do it. I haven't personally implemented OpenCL and OSG integation so can't help directly. Robert.
