 ## Steps to reproduce
 You should be able to reproduce the experiments with a standard Linux machine (laptop, desktop, one cluster node) that has a graphical interface for the Jupyter notebooks. We personnaly used a 16-core Intel Xeon E5-2630 v3 machine from Grid'5000 on which the experiments ran in less than two hours.
