# PETSCPARTITIONERPARMETIS
"parmetis" - A PetscPartitioner object using the ParMETIS library 


## Options Database Keys

- ***-petscpartitioner_parmetis_type <string> -*** ParMETIS partitioning type. Either "kway" or "rb" (recursive bisection)
- ***-petscpartitioner_parmetis_imbalance_ratio <value> -*** Load imbalance ratio limit
- ***-petscpartitioner_parmetis_debug <int> -*** Debugging flag passed to ParMETIS/METIS routines
- ***-petscpartitioner_parmetis_seed <int> -*** Random seed


Notes: when the graph is on a single process, this partitioner actually calls METIS and not ParMETIS
