R and multicore architectures?

Hi,

We are gradually moving most of climate data and model 
output analyses to R. We have a 2 x Core 2 Duo Mac with 9GB 
memory and 3TB disk space, i.e. ideal for such work...

Question: Does the standard (binary distribution) of R use 
all of the cores and access all of the available memory?

Or does one have to recompile R to take advantages of more 
powerful hardware available around?
