Why CPU and GPU load so low in the process of opencv_traincascade?

I build the project with CUDA module. Well, I think I did something incorrect because GPU load in process of train(8000 pos and 3000 neg) is 6%(Nvidia QUADRO). And CPU: On precalculation stage CPU load is 100%(core i7), but then falling down on 12%, and keep working on it. Can you give me some advise, what I should do? I'm new in OpenCV and want to learn it.

EDIT There is no code writing by me. It is a module .exe of OpenCV library.

OpenCV doesn't have implicit CUDA optimization. opencv_gpu is a separate module and users should explicitly use it to enable CUDA optimization. opencv_traincascade doesn't use gpu module, so it doesn't work on GPU.

You can find more information in reference manual: http://docs.opencv.org/2.4.6/modules/gpu/doc/gpu.html

and in gpu samples: https://github.com/Itseez/opencv/tree/2.4/samples/gpu
