Use <A HREF="../KSP/KSPGetIterationNumber.html#KSPGetIterationNumber">KSPGetIterationNumber</A>() to get the count for the most recent solve only
If this is called within a linear solve (such as in a <A HREF="../KSP/KSPMonitor.html#KSPMonitor">KSPMonitor</A> routine) then it does not include iterations within that current solve
