"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 

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.
