Notes
KSPSetUpOnBlocks() is a routine that the user can optinally call for Many brmore precise profiling (via -log_summary) of the setup phase for these Many brblock preconditioners. If the user does not call KSPSetUpOnBlocks(), Many brit will automatically be called from within KSPSolve(). Many br
Calling KSPSetUpOnBlocks() is the same as calling PCSetUpOnBlocks() Many bron the PC context within the KSP context. Many br
