Detailed Description

A base class that can be used for graph builders based on a random number of outgoing edges for each node, according to the specified random distribution.

Static random generators are also available, so that the graph generation process can be controlled with fpmas::seed().

Constructor & Destructor Documentation

RandomGraphBuilder()

template<typename Generator_t , typename EdgeDist >

fpmas::graph::RandomGraphBuilder::RandomGraphBuilder ( Generator_t &  generator, EdgeDist &  edge_distribution  )

inlineprotected

RandomGraphBuilder constructor.

Template Parameters

Generator_t	random generator type (must satisfy UniformRandomBitGenerator)
EdgeDist	edge count distribution (must satisfy RandomNumberDistribution)

Parameters

generator	random generator
edge_distribution	outgoing edge count distribution

Member Function Documentation

seed()

void fpmas::graph::RandomGraphBuilder::seed ( random::mt19937_64::result_type  seed )

static

Seeds the distributed_rd and rd random generators.

Parameters

seed	random seed

Member Data Documentation

num_edge

std::function<std::size_t()> fpmas::graph::RandomGraphBuilder::num_edge

protected

Function object returning a random edge count.

distributed_rd

random::DistributedGenerator fpmas::graph::RandomGraphBuilder::distributed_rd

static

Static and distributed random generator.

rd

random::mt19937_64 fpmas::graph::RandomGraphBuilder::rd

static

Static random generator, that should produce the same random number generation sequences on all processes, provided that the seed() method is properly called with the same argument on all processes (or not called at all, to use the default seed).
