[Rtk-users] About SART with CUDA

[Simon Rit]

Please continue using the mailing list. It's hard too say, maybe the volume
is too big or too small for your GPU. Have you tried doing "make test" to
see if the problem is related to this particular reconstruction or if this
is a more general problem? What is the size of the projection images and
the volume that you use?
