Execo On G5K

Execo offers a Python API to manage processes execution. It is well suited for quick and easy creation of reproducible experiments on distributed hosts. It is a huge improvement over using shell script for experiment development.

It offers:

• Asynchronous control of local and remote commands.
• Efficient and scalable execution (transparent usage of Taktuk).
• Interaction with Grid'5000 resources (planning, submission, deployment, API).
• Tools for rapid development of reproducible experiments.

Installation

Connect on a frontend and use easy_install:

frontend:

easy_install --user execo

Configure your path in .bashrc:

 export PATH="$HOME/.local/bin${PATH:+:${PATH}}"

Create a .execo.conf.py in your home directory if you need some specific configuration

Usage

A complete user guide can be found on gforge.
