Today I solved the bug for more than three levels with MULTILEVEL BDDC. If I have time, tomorrow I will adapt the code to deal with local matrices having a NearNullSpace object attached. Then the next step will be remove explicit calls to METIS and use MatPartitioning routines. Jed: can you give me some quick hints on how they behave? In particular, I wish to know if I can assemble the adjacency on N procs and then partition it in M procs (with M<N).</blockquote>
