SVD speed in CPU and GPU

Question

I\'m testing svd in Matlab R2014a and it seems that there is no CPU vs GPU speedup. I\'m using a GTX 460 car

Answer 1

I have tried to parallelize SVD on my laptop equipped with GTX 460 for over one months, which was also a part of my undergraduate thesis, I did so many experiments that I later discovered that MATLAB is extremely fast and outperforms my code, by the way, I used one side Jacobi, and I have not yet seen any paper that reveals an algorithm faster than svd of MATLAB. On GPU, the time cost of memory copy can be very high if you are not using an elegant model, I refer you to read more about CUDA. If you need any help, please contact me.
