Detailed Description
Sparse Graph that use PETSC for partitioning.
Definition at line 172 of file sparse_graph.hh.
Constructor & Destructor Documentation
◆ SparseGraphPETSC() [1/2]
|
inline |
Construct empty graph only from number of vertices, use default initial distribution.
Definition at line 180 of file sparse_graph.hh.
◆ SparseGraphPETSC() [2/2]
|
inline |
Construct empty graph with given distribution of vertices.
Definition at line 186 of file sparse_graph.hh.
◆ ~SparseGraphPETSC()
|
privatevirtual |
Definition at line 352 of file sparse_graph.cc.
Member Function Documentation
◆ allocate_sparse_graph()
|
privatevirtual |
Use virtual method for allocation since for PETSC interface we have to use PetscMalloc.
Implements SparseGraph.
Definition at line 325 of file sparse_graph.cc.
◆ partition()
|
virtual |
Implementation of partitioning using PETSC interface to various partitioning software.
Implements SparseGraph.
Definition at line 333 of file sparse_graph.cc.
