PETSc version 3.15.5

MatPartitioning

Object for managing the partitioning of a matrix or graph

typedef struct _p_MatPartitioning* MatPartitioning;

There is also a PetscPartitioner object that provides the same functionality. It can utilize the MatPartitioning operations via PetscPartitionerSetType(p,PETSCPARTITIONERMATPARTITIONING)

It is an extra maintainance and documentation cost to have two objects with the same functionality.
