[Rtk-users] Compiling with CUDA

[Simon Rit]

Hi Andy,
It seems that you have very little GPU memory. Do you know what
graphics card you have?
If I were you, I would start with a smaller volume with the
--dimension option if you use my command line tools (modify as well
the spacing at first, e.g., --spacing 8 --dimension 32). You can also
use the --divisions option to split the volume in pieces but you then
redo the filtering of all projection images.
BTW, would you have two graphics card, there is nohing to select one
over the other. Maybe this is what happens to you? You can then modify
"GetListOfCudaDevices" and add some parameters to select the graphics
card based on the memory.
Let me know if I can help more,
Simon
