Look for Rmpi.  I believe it's in the contrib non-current directory on
CRAN.  It works with LAM-MPI, though we've talked about extending it

If interested in programming statistical calculations on a beowulf,
one might consider SNOW, which is an R library which provides a higher
(but simpler) level implementation (independent of PVM or MPI -- will
even use socket-based communication on a cluster if you don't have
it), and integrates transparently with SPRNG (the scalable parallel



and Lecture/Lab 4 for description/issues in interactively computing
statistical quantities on a computational cluster (for statisticians
who don't want to figure out communication, and just want to get
results faster).

(I'm biased in my view -- we wrote the wrappers to PVM and SPRNG for
R, as well as contributed to SNOW, and just need to extend the current
set of MPI wrappers).
