"In today's CPU-GPU computing schemes, when a CPU senses that a process 
upon which it is working might benefit from a GPU's muscle, it has to 
copy the relevant data from its own reservoir of memory into the GPU's – 
and when the GPU is finished with its tasks, the results need to be 
copied back into the CPU's memory stash before the CPU can complete its 
work."


That last time I checked, CPUs don't sense anything - the programmer has 
has to write the program to  use the GPUs muscle.

Other than that flub, a good article, and interesting technology.
