This repository contains the code for the experiment presented in the paper
"On the Algebraic Properties of Flame Graphs".
## How to run the experiment
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
~~~console
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
~~~console
python experiment.py
~~~
The 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
