Modern GPU's are SIMD processors that execute the same program on
multiple data-elements (e.g. vertices or pixels) in parallel.


Restructuring compilers are able to extract such parallelism from loop
nests by dependence analysis (determining which loop interations are
independent) and loop transformations (re-ordering iterations while
preserving the program operation). In addition, you would need to
partition the code between CPU and GPU and handle communication of
data between the two.
