It depends on the GIS software used. There was some work
to mpi-enable GRASS modules a while back, no idea where it
went. Here is something about a parallel version of s.surf.rst:

And of course if you program against the GIS api's you
might be able to take advantage of a cluster as well.

There is a paper that mentiones they used MPI for paralelizing
their GIS/EM4 software on http://www.colorado.edu/research/cires/banff/pubpapers/104/
