R doesn't have built-in parallelism features that I know of. There are a lot of packages, though: http://cran.r-project.org/web/views/HighPerformanceComputing.h

  Most of the things can be transformed through lapply family (and d/plyr equivalents). d/plyr has simple parallel=TRUE. For other problems use mclapply(). That's basically all you need on a day-to-day basis.

  The 'parallel' package has been included in recent versions of R and has RNGs for parallel execution and variations of the `apply` functions. For "embarrassingly parallel" calculations these work as drop-in replacements. It's built-in in the same way that MASS and lattice are.
