[Rtk-users] SART GPU usage is like 2~3%

[Albert M]

Hi,

I'm using GPU (NVIDIA TITAN Xp) to reconstruct tomosynthesis images by SART
method, i've no error and apparently results are fine.
In addition GPU reconstruction it's 2x faster than SART CPU (normal)
reconstruction (200sec vs 400sec)

But GPU usage is like 2~3%. Why is so low? How I can increase this?

PD:  I'm using cuda at SART setting SetBackProjectionFilter and
SetForwardProjectionFilter at 2.


Can someone help me?

Thank you!
