PetscMallocDump#
Dumps the currently allocated memory blocks to a file. The information printed is: size of space (in bytes), address of space, id of space, file in which space was allocated, and line number at which it was allocated.
Synopsis#
#include "petscsys.h" 
PetscErrorCode PetscMallocDump(FILE *fp)
Not Collective
Input Parameter#
- fp - file pointer. If - fpis- NULL,- stdoutis assumed.
Options Database Key#
- -malloc_dump - - Print summary of unfreed memory during call to- PetscFinalize(), writing to filename if given
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
This only does anything if -malloc_debug (or -malloc_test if PETSc was configured with debugging) has been used
Fortran Notes#
The calling sequence is PetscMallocDump(PetscErrorCode ierr). A fp parameter is not supported.
Developer Notes#
This should be absorbed into PetscMallocView()
