About:

This is a C++ implementation of the stochastic growth process dubbed Structural Preferential Attachment (SPA). See our official website for more informations.

Quick Start

Compilation

spa_networks uses features from C++11 and must therefore be compiled with gcc-4.6 or clang-3.7 (or a newer version).

Using CMake

Compiling with cmake should be straightforward:

cmake .
make

The available options for cmake are

  • OPTMEM_MODE
  • HPC_MODE
  • FORCE_NO_BOOST

OPTMEM_MODE favors a small memory footprint over speed.

HPC_MODE silences all output and compiles assertions out.

The options can be passed to the usual GUI or through the command line interface:

cmake -DOPTMEM_MODE=ON .
make

The build has been tested with cmake-2.8 and cmake-3.4, on OSx and GNU/Linux, with gcc and clang.

Using GCC

The explicit compilation call below should work on most *nix systems

g++ -o3 -W -Wall -Wextra -pedantic -std=c++0x  spa_main.cpp modular_structure.cpp spa_network.cpp subgraph.cpp spa_algorithm.cpp interface.cpp output_functions.cpp misc_functions.cpp includes/logger.cpp -lboost_program_options -o SPA

Compilations options can be manually adjusted in the src/config.h file.

Execution

Multiple parameters must be set for each simulation of the SPA process. These parameters can be passed through a configuration file

./spa_networks -c path/to/config/file.txt

Note that ./spa_networks -g generates an empty configuration file template. If boost::program_options is installed and properly linked to the binary, parameters will also be accepted directly from the command line. See

./spa_networks -h 

for more information about each flags.

Output

The results of a simulation can be found in the directory from which spa_networks is called. This default behavior can be modified with the -B / --base_path= flag (by specifying a new absolute or relative path). Note that outputs are not computed unless specifically requested. So, for example, there won't be an edge list file, unless the user specifies a file name for the edge_list. e.g. --edge_list=TestEdgeList.txt.

Papers:

More information about the SPA process can be found in the following papers.
