<A HREF="../KSP/KSPSetUpOnBlocks.html#KSPSetUpOnBlocks">KSPSetUpOnBlocks</A>() is a routine that the user can optinally call for
more precise profiling (via -log_summary) of the setup phase for these
block preconditioners. If the user does not call <A HREF="../KSP/KSPSetUpOnBlocks.html#KSPSetUpOnBlocks">KSPSetUpOnBlocks</A>(),
it will automatically be called from within <A HREF="../KSP/KSPSolve.html#KSPSolve">KSPSolve</A>().
<P>
Calling <A HREF="../KSP/KSPSetUpOnBlocks.html#KSPSetUpOnBlocks">KSPSetUpOnBlocks</A>() is the same as calling <A HREF="../PC/PCSetUpOnBlocks.html#PCSetUpOnBlocks">PCSetUpOnBlocks</A>()
