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()`](http://docs.opencv.org/3.1.0/d3/d63/classcv_1_1Mat.html#afd5159655a12555b5c2725c750893a46) use the GPU if it is available? Is there a way I can test whether `Mat::dot()`is using the GPU?
