Detailed Description

Sparse Graph that use METIS for partitioning.

Definition at line 205 of file sparse_graph.hh.

Constructor & Destructor Documentation

SparseGraphMETIS::SparseGraphMETIS	(	int	n_vtxs,
		MPI_Comm	comm
	)

inline

Construct empty graph only from number of vertices, use localized distribution in order to use sequential METIS library.

Definition at line 212 of file sparse_graph.hh.

SparseGraphMETIS::SparseGraphMETIS ( const Distribution & distr )

inline

Construct empty graph with given distribution of vertices.

Definition at line 218 of file sparse_graph.hh.

void SparseGraphMETIS::allocate_sparse_graph	(	int	lsize_vtxs,
		int	lsize_adj
	)

privatevirtual

Use virtual method for allocation since for PETSC interface we have to use PetscMalloc.

Implements SparseGraph.

void SparseGraphMETIS::partition ( int * loc_part )

virtual

Implementation of partitioning using METIS.

Implements SparseGraph.
