virtual int SetParameters(Teuchos::ParameterList &List)
Sets all the parameters for the partitioner (none at moment).
Ifpack_METISReordering: A class to reorder a graph using METIS.
virtual int Pinv(const Epetra_MultiVector &Xorig, Epetra_MultiVector &X) const
Applies inverse reordering to multivector Xorig, whose local length equals the number of local rows...
virtual bool IsComputed() const
Returns true is the reordering object has been successfully initialized, false otherwise.
Ifpack_METISReordering()
Constructor.
bool IsComputed_
If true, the reordering has been successfully computed.
Ifpack_Reordering: basic class for reordering for a Ifpack_Graph object.
virtual int Reorder(const int i) const
Returns the reordered index of row i.
int NumMyRows_
Number of local rows in the graph.
bool UseSymmetricGraph_
If true, the graph has to be symmetrized before calling METIS.
adjacency_list< vecS, vecS, undirectedS, no_property, property< edge_weight_t, double > > Graph
virtual int InvReorder(const int i) const
Returns the inverse reordered index of row i.
virtual int SetParameter(const std::string, const double)
Sets double parameters `Name'.
virtual int Compute(const Ifpack_Graph &Graph)
Computes all it is necessary to initialize the reordering object.
virtual ~Ifpack_METISReordering()
Destructor.
std::vector< int > Reorder_
Contains the reordering.
Ifpack_Graph: a pure virtual class that defines graphs for IFPACK.
virtual int SetParameter(const std::string Name, const int Value)
Sets integer parameters `Name'.
virtual int P(const Epetra_MultiVector &Xorig, Epetra_MultiVector &X) const
Applies reordering to multivector Xorig, whose local length equals the number of local rows...
virtual std::ostream & Print(std::ostream &os) const
Prints basic information on iostream. This function is used by operator<<.
std::vector< int > InvReorder_
Contains the inverse reordering.
