KSPGetTotalIterations

 Gets the total number of iterations this KSP object has performed since was created, counted over all linear solves

Synopsis

#include "petscksp.h" 
PetscErrorCode  KSPGetTotalIterations(KSP ksp,PetscInt *its)
Not Collective

Input Parameters

ksp -the iterative context

Output Parameters

its -total number of iterations

Notes: Use KSPGetIterationNumber() to get the count for the most recent solve only If this is called within a linear solve (such as in a KSPMonitor routine) then it does not include iterations within that current solve

Keywords
