Topic Avoiding the ecological catastrophe will require a joined effort from every actor of society. Our intensive and growing use of digital technologies must be questioned. We postulate that some environmental-aware individuals are willing to reflect upon and reduce the footprint associated to their digital usages.
Similarly to the Low-tech Magazine[1], a solar-powered and very lightweight website, this internship will study an off-grid “sufficient”[2] data center in which a part of the users accepts to contribute to the environmental effort.

Contexte Dans le monde du calcul à haute performance, un supercalculateur est une plateforme de calcul utilisée par de nombreux utilisateurs pour y exécuter des applications, notamment pour lancer des campagnes de simulations scientifiques à grande échelle. Les supercalculateurs récents peuvent avoir un nombre très grand de ressources (de l’ordre du million de cœurs) et les utilisateurs n’accèdent donc pas directement aux ressources ; ils passent par l’intermédiaire d’un gestionnaire de ressources (comme SLURM[1]) pour réserver des nœuds/cœuds de calcul et pour y exécuter des applications.
Topic Researchers use simulations to compare the performance (execution time, energy efficiency, …) of different scheduling algorithms in High-Performance Computing (HPC) platforms. The most common method is to replay historic workloads recorded in real HPC infrastructures (like the ones available in the Parallel Workloads Archive): jobs are submitted to the simulation at the same timestamp as in the original log.
A major drawback of this method is that it does not preserve the submission behavior of the users of the platform.
Duration: between 16 and 18 months
Remuneration: depending on profile and experience, according to the University’s salary scale (from 2700 to 3600 € gross monthly). Position to be filled as soon as possible. The applications will be evaluated as soon as they arrive.
Location: IRIT laboratory, Paul Sabatier University (Toulouse, in France)
Following the ANR DATAZERO [1] project (2015-2019), this position is placed in the context of the ANR Datazero2 (2020-2024).
