Parallel BGL Concept Distributed Vertex List Graph

Contents

Description

A Distributed Vertex List Graph is a graph whose vertices are distributed across multiple processes or address spaces. The vertices and num_vertices functions retain the same signatures as in the Vertex List Graph concept, but return only the local set (and size of the local set) of vertices.

Notation

G
A type that models the Distributed Vertex List Graph concept.
g
An object of type G.

Refinement of

Associated types

Vertex descriptor type graph_traits<G>::vertex_descriptor Must model the Global Descriptor concept.
Vertex iterator type graph_traits<G>::vertex_iterator Iterates over vertices stored locally. The value type must be vertex_descriptor.
Vertices size type graph_traits<G>::vertices_size_type The unsigned integral type used to store the number of vertices in the local subgraph.

Valid Expressions

Name Expression Type Semantics
Local vertex set vertices(g) std::pair< vertex_iterator, vertex_iterator> Returns an iterator range providing access to the local vertices in the graph.
Number of local vertices. num_vertices(g) vertices_size_type Returns the number of vertices stored locally in the graph.
