[R] parallel R?

Hi all,

Lots of big IT companies are renting out their computing facilities.
Amazon has one such service. In my understanding, this will
dramatically improve the speed of my R program -- currently the cross
validation and model selection part is the bottle neck. It take a few
days to just finish optimal parameter tuning via CV.

Could anybody shed some lights on this? Is it completely transparent
to move my R program to a rented parallel computing facility?

Moreover, at my PC level, I have a 4-core PC, is there anything we
could do in R to speed up my CV programs?

Thanks a lot!
