In OpenCV 3.1 will Mat::dot() use the gpu if it is available?

I am not too sure when I should expect the transparent API to be able to use the GPU and when not.

Will Mat::dot() use the GPU if it is available?

Is there a way I can test whether Mat::dot()is using the GPU?

No Mat is CPU only, but UMat will do .

You can build OpenCV from source and debug into source code to check if OpenCL is used.

Thank you. This tells me exactly what I need to know.
