You really start to make more and more sense ;-) .
As for parallel implementation that makes it easy, a look at CUDA may be 
beneficial. Submitting a multidimensional matrix and function to be 
performed across cores on it, has probably a better chance than using loops, 
although both can solve the problem. The NVidia also will queue the 
On another hand, the modern Intel/AMD CPUs come with only maximum of 8 
cores/half cores, and they will barely reach 16 sometime next year. This 
type of processing may not offer as much advantage as on Sparks or NVidia 
GPUs where you have hundreds of cores. It may be a bit early to add this 
functionality in the compilers today, but you never know.
For 16 or less cores the traditional Threading approach is probably a better 
fit than matrix/loop type of queued execution.
