The documentation for package intamap suggest that you first download
and load package doSNOW from CRAN, and then pass the nclus parameter
with a number larger than 1, as argument:
Looking at the code, it tries to set up nodes on localhost, so for
distributing load over a cluster composed of different machines, you (or
we) would have to modify the code.
Package gstat has a demo script, demo(snow), that shows how to
distribute predictions over multiple hosts.
