Detailed Description

Class MHO_MBDelaySearchCUDA.

This is an ultra basic CUDA implementation of the the coarse MBD/SBD/DR search, its quite primitive and only calls the CUFFT library to speed up the inner-most loop over (DR,MBD) space. It is not optimized and has far too much movement of data between host <-> device, additional work is need to optimize this routine.
