I must admit I'm not really familiar with Nvidia's Monte Carlo example. As 
long as the function you're trying to recode doesn't pass pointers to shared 
memory, what you suggest should be possible. I can't quite say whether it's 
going to be efficient, that depends on a rather large number of factors.
