[R] snow package on multi core unix box

[Saeed Abu Nimeh]

Is the rmpi package (or rpvm) needed to exploit multiple cores on a
single unix box using the snow package. The documentation of the package
does not provide info about setting up a single machine with multiple
cores. Also, if how effective is it to run a bayesian simulation on
parallel (or distributed) processors using the snow package.
Thanks,
Saeed
