How should it summarize? (There are so many things that could be different.) Would it be okay to say "Subdomain solver on other processes, use -mg_coarse_pc_bjacobi_view_all_subdomains for details"? What should we do with 3.4? -ksp_view is currently unusable when run with -pc_type gamg, especially on more than a handful of processes.
