  abstract = {A parallel version of an adaptive multigrid solver for
		  partial differential equations is considered. The main
		  emphasis is put on the load balancing algorithm to
		  distribute the adaptive grids at runtime. The background
		  and some applications of space-filling curves are
		  discussed, which are later on used as the basic principle
		  of the load-balancing heuristic. A tight integration of
		  space-filling curves as a memory addressing scheme into the
		  numerical algorithm is proposed. Some experiments on a
		  cluster of PCs demonstrates the parallel efficiency and
		  scalability of the approach. }
