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.
PetscErrorCode PetscMallocDump(FILE *fp)
fp -file pointer. If fp is NULL, stdout is assumed.
Options Database Key
-malloc_dump <optional filename> -Dumps unfreed memory during call to PetscFinalize()
The calling sequence in Fortran is PetscMallocDump(integer ierr)
The fp defaults to stdout.
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
