Project Description

This library implements a decoder for a Boldi-Vigna graph structure, a highly compressed means of storing web-graphs. The library is written in pure C. It includes a Python interface, and a means to implement multi-threaded graph algorithms.

Features

  • In-memory and on-disk graph storage
  • Sequential iteration over graph edges
  • Parallel iteration over graph edges
  • random access to graph edges

Installation

1.1 Install with pip:

pip install pylibbvg

1.2 Uninstall:

pip uninstall pylibbvg

2.1. Compile from the source code(Cython is assumed to have installed):

python setup.py build_ext --inplace

2.2. To clean the library:

python setup.py clean

Synopsis

To use the library in Python code:

import bvg
G = bvg.BVGraph('wb-cs.stanford', 0) # sequential scan
print 'nodes = ' + str(G.nverts)
print 'edges = ' + str(G.nedges)
edges_and_degrees = G.edges_and_degrees()
for (src, dst, degree) in edges_and_degrees:
    print 'node ' + str(src) + ' has degree ' + str(degree)
    print 'edge: ' + str(src) + ' -> ' + str(dst)
