Other Configuration Files

This section describes other configuration files. These include comparison configuration files, petri settings files, and petri batch files.

Comparison Configuration Files

Note

Comparison configuration files are ugly and use eval. If you have time, refactor them to use JSON or some other method.

A comparison is a set of simulations where one or more option is varied. Comparisons make it easy to see the effects of different configuration options.

A comparison configuration file describes which options should be varied. By convention, it is named cmp.cfg.

The first line of a comparison configuration file is a tuple of options to be varied. Subsequent lines are tuples of values which those options should be set to for a run.

Lines which begin with ( are evaled.

This example configuration file will run three simulations with different values of strong_chance and strong_factor:

('strong_chance', 'strong_factor')
(1.0, 1.0)
(0.01, 0.2)
(0.001, 0.1)

Petri Settings Configuration Files

Petri loads default settings from petri_settings.cfg, which is in INI format. Command line arguments then override these defaults.

In petri settings files, $config refers to pykaryote’s internal configuration directory located at pykaryote/configs.

Here is an example petri_settings.cfg file:

[settings]
output_data_dir = ~/pykaryote/mpi_simulations

[default-comparison]
comparison_config = $config/cmp.cfg
simulation_config = $config/sim.cfg
comparison_name = comparison
num_runs = 60

Petri Batch Configuration Files

petri batch <batch_config_file> runs a batch of comparisons. Petri batch configuration files use INI syntax. Each section of the file is the name of a comparison to run.

Here is an example petri_batch.cfg file:

[default_comparison_50_runs]
comparison_config = ~/pykaryote/pykaryote/configs/cmp.cfg
simulation_config = ~/pykaryote/pykaryote/configs/sim.cfg
num_runs = 50

[default_comparison_10_runs]
comparison_config = ~/pykaryote/pykaryote/configs/cmp.cfg
simulation_config = ~/pykaryote/pykaryote/configs/sim.cfg
num_runs = 10
