Detailed Description

Sparse Graph that use PETSC for partitioning.

Definition at line 172 of file sparse_graph.hh.

Constructor & Destructor Documentation

SparseGraphPETSC::SparseGraphPETSC ( int  n_vtxs, MPI_Comm  comm  )

inline

Construct empty graph only from number of vertices, use default initial distribution.

Definition at line 180 of file sparse_graph.hh.

SparseGraphPETSC::SparseGraphPETSC ( const Distribution &  distr )

inline

Construct empty graph with given distribution of vertices.

Definition at line 186 of file sparse_graph.hh.

SparseGraphPETSC::~SparseGraphPETSC ( )

privatevirtual

Definition at line 351 of file sparse_graph.cc.

Member Function Documentation

void SparseGraphPETSC::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.

Definition at line 324 of file sparse_graph.cc.

void SparseGraphPETSC::partition ( int *  loc_part )

virtual

Implementation of partitioning using PETSC interface to various partitioning software.

Implements SparseGraph.

Definition at line 332 of file sparse_graph.cc.
