Ifpack_Graph: a pure virtual class that defines graphs for IFPACK.
Ifpack_METISReordering: A class to reorder a graph using METIS.
Ifpack_METISReordering()
Constructor.
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 int InvReorder(const int i) const
Returns the inverse reordered index of row i.
virtual std::ostream & Print(std::ostream &os) const
Prints basic information on iostream. This function is used by operator<<.
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 ~Ifpack_METISReordering()
Destructor.
virtual bool IsComputed() const
Returns true is the reordering object has been successfully initialized, false otherwise.
virtual int SetParameter(const std::string Name, const int Value)
Sets integer parameters ‘Name’.
virtual int Compute(const Ifpack_Graph &Graph)
Computes all it is necessary to initialize the reordering object.
virtual int SetParameter(const std::string, const double)
Sets double parameters ‘Name’.
virtual int Reorder(const int i) const
Returns the reordered index of row i.
virtual int SetParameters(Teuchos::ParameterList &List)
Sets all the parameters for the partitioner (none at moment).
Ifpack_Reordering: basic class for reordering for a Ifpack_Graph object.
