WASTE — A CUDA Emulator

CUDA C++ is a parallel programming language for NVIDIA GPU’s.  Using the CUDA Toolkit (http://developer.nvidia.com/object/cuda_3_2_toolkit_rc.html), developers can write programs that take advantage of the large parallel computing potential of the GPU, speeding up their programs several orders of magnitude.  CUDA programs are executed on the GPU, which works as a coprocessor with the CPU, having its own memory and instruction set.  But, the question is, after the developer invested the time to parallelize his program, can the CUDA program run on a PC without an NVIDIA GPU?   Does the developer have to redo all his software?
