[R] Parallelizing spatial computations

[Virgilio Gómez Rubio]

Hi,

I have to run lots of simulations based on several spatial scan
statistics. Since the main overhead is due to a call to 'apply' , I 
was wondering whether it could be possible to parallelize this "loop".

I know there are a few packages for parallel computing in R but I don't
know whether it's worth trying them. Have anyone used these packages
before?

I have a linux machine with two 700-MHz processors and 256 Mb RAM. I
know it's not too much, but I hope to save some time by using both
processors.

Thank you in advance.
