R on a multi core unix box

You can use the socket implementation of snow, with

     library(snow)
     cl <- makeCluster(rep("localhost", 2), type="SOCK")

to start up a cluster of 2 R processes.

Hi,
I installed the snow package on a unix box that has multiple cores. To be
able to exploit the multiple cores (on one pc) do I still need to install
the rmpi package (or rpvm). Another question, if i run a bayesian simulation
on the multiple core after setting them up correctly (using snow), would you
think there will be a noticeable speedup gain.
Thanks,
Saeed
