OpenCL communication management on APU

Hi,

 

I am new to OpenCL and there is something that I do not really understand about OpenCL programming on APUs.

I know that on a classic CPU+GPU combination, I will have to add explicit communications to describe the data movement between the CPU and the GPU. But is it the same for APUs ? or the fact that they are both on the same chip implies that explicit communications aren't required anymore ?

 

Thanks a lot!
