Thanks for the reply. currently i am not using autorun kernel.

I need to pass a 4K Image(3840x2160) pixels from kernel1 to kernel2 via channels.

1. Is there any restriction on the size of buffer to pass address from one kernel to another ?

2. "Instead of passing pointer, send the actual data" For this we need to pass an array of size pix[3840x2160], which is really big. Is their any alternative approach for passing this kind of huge buffers from one kernel to other.
