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. } }
