1) See eg 'Section 6: Random-number generation' in the vignette of the
package "parallel" (part of base R) for an introduction.
2) Even the most naive Google search for 'Rmpi parallel RNG' (and you surely
tried something like that first, yes?) leads to this fine poster by the
author of the Rmpi package:
http://www.stats.uwo.ca/faculty/yu/Rmpi/download/rsr/poster.pdf
which contains an example.
