Hi, I want to refine the renumbering method in ex2.c. Firstly determine the inner nodes and boundary nodes for each processors and then distribute boundary nodes to different processors according to the number of the inner nodes in the processor. For example, if the processors holds more inner nodes, it will receive few boundary nodes for the consideration of load balancing. At last renumber the nodes for each processor. I am not sure if this is a good method. Is there optimal method for renumbering?
Thanks a lot. Yixun
