Ifpack_Graph: a pure virtual class that defines graphs for IFPACK.
Ifpack_UserPartitioner: A class to define linear partitions.
int ComputePartitions()
Computes the partitions. Returns 0 if successful.
Ifpack_UserPartitioner(const Ifpack_Graph *Graph)
Constructor.
int SetPartitionParameters(Teuchos::ParameterList &List)
Sets all the parameters for the partitioner (none for linear partioning).
virtual ~Ifpack_UserPartitioner()
Destructor.
