Nowhere, as CUDA is not suitable (read: it is unable) to implement general
ray-tracing algorithms. All you can do is implement a few special cases.

in particular, "the recursive raytracing algorithm" would not be as
recursive anymore... :P

People are doing raytracing using CUDA, and getting very good performance
results, but I think the feature-set is quite limited. I understand that the
next NVIDIA GPU architecture will support full C++ on the device side, meaning
recursion will be possible. It also is more focused toward double precision,
which is good.
They're talking about a consumer release Q1 2010, with the HPC release May 2010.

no but here is a somewhat newer thread:

don't hold your breath though
