Function Details

garbage_cleanup(comm=None)

Cleans up unused PETSc objects on the communicator comm. If no

communicator is provided first clean up on PETSC_COMM_WORLD, then clean up on PETSC_COMM_SELF.

Optional argument comm=None.

No return value.

garbage_view(comm=None)

Prints out summary of the unused PETSc objects on each rank of

the communicator comm. If no communicator is provided then PETSC_COMM_WORLD is used.

Optional argument comm=None.

No return value.
