I have never tested, but parallel assembly is getting closer. It remains to reorder the degrees of freedom (class DofMap) so we get an efficient numbering scheme for parallel assembly. A simple demo is available in src/sandbox/pmesh/main.cpp I hope we'll have something that works ok (just assembly) next week. > I'm getting petsc errors of the > following sort.
