Diversity and Community Can Co-exist

Software

This software is free under the terms of the GNU General Public License. It is derived from code developed for an earlier publication Ultrametric distribution of culture vectors in an extended Axelrod model of cultural dissemination. It uses Python and parallelization using MPI (with mpi4py). It also requires the Python libraries NumPy (part of the SciPy package) and igraph.

The Python code was run with NumPy version 1.6.2, SciPy version 0.7.2, igraph version 0.6 and mpi4py version 1.3.1 under Python version 2.6.6 on an IBM iDataplex x86 cluster (1120 Intel Sandybridge cores running at 2.7GHz) running Linux (RHEL 6) with Open MPI version 1.6.5. The C++ code was compiled with gcc version 4.9.1.

Running the models

The paper describes two models:

• Model 1: Extended Schelling model with mean similarity. This model can be run with a command line such as: mpirun --mca mpi_warn_on_fork 0 python ./physicaa2012-python-mpi/src/axelrod/geo/schelling/main.py F:1 ./lattice-schelling-meanoverlap-network/model end 500

• Model 2: Extended Axelrod-Schelling model. This model can be run with a command line such as: mpirun --mca mpi_warn_on_fork 0 python ./physicaa2012-python-mpi/src/axelrod/geo/expphysicstimeline/multiruninitmain.py F:5 ./lattice-axelrod-schelling-nealnetwork-cpp-end/model end 500
