Execo (http://execo.gforge.inria.fr ) is a Python library designed for rapid prototyping of experiments on distributed systems, automatization of system administration tasks (such as deployment and configuration of distributed middleware), and creation of reproducible experiments scripts. It allows easy and asynchronous management of thousands of local or remote unix processes and offers tools for easy usage of the Grid'5000 platform services.

Execo currently has more than 20 users in and outside the AVALON team, who rely on it to automate experimental workflows. It was used to develop one of the two contenders who won the 2014 Grid'5000 Large Scale Deployment Challenge. It is used as a building block in the Grid'5000 metrology service and has been used to produce experimental results involved in numerous papers and reports.

It is distributed under GPLv3 and it is made of 7200 lines of code.
