You should be able to use snow with open-mpi on your macpro. You should also be
able to use snow with the "sockets" method, e.g.
cl <- makeCluster(rep("localhost", 8), type = "SOCK")
Note that there's a separate list, R-sig-hpc, for parallelisation issues.

of my MacPro using snow or MPI/PVM has to be absolutely install and run across
multiple machine. Is there an alternative that I could use to take advantage of
my 8 cores with R?
