Hi,

write a CUDA program + the MathLink templates, preprocess
it with mprep and compile the output with nvcc. Install it in a 
Mathematica session and you are done ...

But keep in mind, that if you can only parallelize 50 % of your code,
than an infinite number of processors will speed up you calculation
only by a factor of 2.

Regards
