No it does not. It uses new grass python libraries to initiate multiple processes on different cores.

It uses some of the new r.mapcalc capabilities to do parallel processing on multi-core processors. So it's pretty fast. Michael ____________________ C.

In other worlds to incorporate v.generalize/i.orto.photo code into GMath lib. Any pointers here?
