I was wondering when someone would ask about this.  Short answer is
that there are cases where CUDA (and/or OpenCL) might be useful*, but
it is unlikely to have a significant impact on the runtime of most
existing programs in Phenix.  Various other algorithmic improvements
are more likely to have a substantial impact on speed than optimizing
our code for fancy hardware, especially for phenix.refine.


(* and some work is actually being done on this in CCTBX, but not as
part of Phenix per se.)
