pyorder's Introduction

PyOrder --- A Library of Sparse Matrix Reordering Methods in Python

Requirements

NumPy
The Harwell Subroutine Library subroutines MC21 and MC60. More interfaces may be added as needed. Head to http://hsl.rl.ac.uk/hsl2007/hsl20074researchers.html for license terms and for obtaining the software. You need to download the double precision real version. Edit site.cfg to specify the location of the source files.
If you plan to read and write matrices in Harwell-Boeing or Rutherford-Boeing format, you will need to install fortranformat, available from PyPi.

Installation

For now, just:

python setup.py build
python setup.py install

To select another Fortran compiler:

python setup.py config_fc --fcompiler=<Fortran compiler name> build

For instance:

python setup.py config_fc --fcompiler=gfortran build

assuming gfortran is in your PATH.

To see a list of available Fortran compilers and their names:

python setup.py config_fc --help-fcompiler

Examples

You can test that your installation is working correctly by running the examples. Change to the examples directory and type:

% python demo_mc21.py
% python demo_mc60.py
% bunzip2 commanche_dual.rb.bz2
% python demo_hb_mc60.py commanche_dual.rb
% python demo_hb_mc60_pro.py commanche_dual.rb
% python demo_hb_mc21.py commanche_dual.rb

If Matplotlib is installed, some sparsity pattern plots should pop up.

Examining the example scripts is a good idea.

Documentation

See http://dpo.github.com/pyorder.

There is a PDF manual in doc/PyOrder.pdf. The html documentation can be generated by changing to the doc directory and issuing make html. Sphinx is required to generate the documentation.
