Calling Kernel Function from global or device function How to get paralelism if you are on device si

Hi there

Is there any chance to get paralleslism from device side, as calling global functions from host, simultaneously nxm times using kernel invocation <<<G,B>>>. The obvious question is NOT THERE IS NO CHANCE, because i couldn’t find any informatioan how to use threads from device side, from global or device function. But maybe there is some workaround for that problem, because why you can run prarallel something from host and cannot from device. Do you know the anserwes of my considerations???

Thank you for helping a greenhorn.
