[R-SIG-Mac] Multiple threads on MacPro

[Max Kuhn]

You might want to take a look at Dirk's course notes:

   dirk.eddelbuettel.com/papers/bocDec2008introHPCwithR.pdf

to understand what R can do in general. I use nws and Rpmi (via the
snow package). I haven't tried the multicore package yet.

You have the required libraries for mpi, so you might want to start
there. The snow package is pretty easy to used, as is foreach.
