Using multicores in R

Hi,

I have an R script which is time consuming because it has two nested loops
in it of at least 5000 iterations each, I have tried to use the multicore
package but id doesn't seem to improve the elapsed time of the script(a
shorter script for example) and I can't use the mcapply because of technical
reasons.

I was wondering how can I make my script use more cores and memory because I
am running it on a server and it is a shame that it uses only one core. 

Thanks!
Moriah
