CPU and GPU

[generalgaowei]

I feel that the code is executed on GPU. Could you tell me how the project use and balance the compute capabilities of multiple GPUs and CPUs?

Like you said, Radeon Rays only executes ray tracing code on GPU. It's not intended for using CPU,

However you could imagine doing your ray tracing on GPU while you do something else on CPU, but that is not in scope of this project.
