Synopsis
#include "petscsys.h"
PetscErrorCode PetscMallocDump(FILE *fp)
Not Collective
Input Parameter
| fp | - file pointer. If fp is NULL, stdout is assumed.
|
Options Database Key
| -malloc_dump <optional filename> | - Dumps unfreed memory during call to PetscFinalize()
|
Fortran Note
The calling sequence in Fortran is PetscMallocDump(integer ierr)
The fp defaults to stdout.
Notes
Uses MPI_COMM_WORLD to display rank, because this may be called in PetscFinalize() after PETSC_COMM_WORLD has been freed.
When called in PetscFinalize() dumps only the allocations that have not been properly freed
PetscMallocView() prints a list of all memory ever allocated
