This repository contains the code for the experiment presented in the paper "On the Algebraic Properties of Flame Graphs".
The experiment has been run with CPython 3.9 and Austin 3.4.1 (from the Snap store) on Ubuntu 22.04. We recommend creating a virtual environment and installing the dependencies with
pip install -r requirements.txt`The data can be collected by running the collect_data.sh bash script. The
samples will be saved in the data directory. The experiment can then be run
with
python experiment.pyThe output will contain the p-value and the Delta decomposition of the difference of the average flame graph, with stacks filtered out as described in the paper.
This is the result we obtained with a run of the experiment
p-value: 1.1102230246251565e-16
