I think we need more information to figure out exactly what the problem is... Can you run with -log_summary so we can see more information about what solvers PETSc is using? I suppose it's possible that you accidentally built a serial PETSc and an MPI-enabled libmesh, but it seems unlikely that combination would even run... How do you know that "other processes" do run in parallel? -- John ------------------------------------------------------------------------------ Want excitement?
