PCSORGetIterations

Gets the number of inner iterations to be used by the SOR preconditioner. The default is 1.

#include "petscpc.h" 
PetscErrorCode  PCSORGetIterations(PC pc,PetscInt *its,PetscInt *lits)

Logically Collective on PC

pc -the preconditioner context

	lits	- number of local iterations, smoothings over just variables on processor
	its	- number of parallel iterations to use; each parallel iteration has lits local iterations

	-pc_sor_its <its>	- Sets number of iterations
	-pc_sor_lits <lits>	- Sets number of local iterations

When run on one processor the number of smoothings is lits*its
