PetscFinalize#
Checks for options to be called at the conclusion of a PETSc program and frees any remaining PETSc objects and data structures. of the program. Automatically calls MPI_Finalize() if the user had not called MPI_Init() before calling PetscInitialize().
Synopsis#
#include "petscsys.h"   
PetscErrorCode PetscFinalize(void)
Collective on PETSC_COMM_WORLD
Options Database Keys#
- -options_view - Calls - PetscOptionsView()
- -options_left - Prints unused options that remain in the database 
- -objects_dump [all] - Prints list of objects allocated by the user that have not been freed, the option all cause all outstanding objects to be listed 
- -mpidump - Calls PetscMPIDump()

- -memory_view - Prints total memory usage 
- -malloc_view - - Prints list of all memory allocated and in what functions
