Cycles hybrid CPU + GPU OpenCL renderer?

Hi there,

Does Cycles has support for hybrid CPU + GPU renderer for OpenCL, such that I can use both CPU cores and an AMD GPU simultaneously?

I tried setting both CPU and GPU under system preferences / OpenCL, and then selected ‘GPU compute’ from render options. But it does not look like it is using both CPU and GPU. If I set number of threads as 1, I expect to see two tiles during rendering (1 for CPU and 1 for GPU), but I only see one tile rendered at a time.

I am using the latest commit of master branch from GitHub.


What happens when you put the number of threads to automatic?
