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()
-malloc_dump
- CallsPetscMallocDump(), displays all memory allocated that has not been freed-memory_view - Prints total memory usage
-malloc_view
- Prints list of all memory allocated and in what functions
Note#
See PetscInitialize() for other runtime options.
You can call PetscInitialize() after PetscFinalize() but only with MPI-Uni or if you called MPI_Init() before ever calling PetscInitialize().
