Titre : Présentation et démonstration Nix/NixOS/NixOS-Compose 

Résumé:
Dans cette présentation, nous motiverons l’utilisation de
gestionnaires de paquets fonctionnels, tels que Nix [1] ou Guix [2],
pour la mise en place d’environnements logiciels reproductibles.
Nous expliquerons ensuite les concepts importants de ces outils,
puis illustrerons leurs utilisations par une démonstration.
(use case: analyse de données sur sa machine)

Nix se concentre uniquement sur la pile logicielle au-dessus
du noyau, nous présenterons également NixOS [3], la distribution
Linux basée sur Nix, qui permet de produire des images systèmes
reproductibles.
(use case: expérience sur G5K avec un nœud)

Enfin, nous présenterons NixOS-Compose [4], un outil se basant sur
NixOS, visant à faciliter les cycles de mise au point
d’environnement logiciels distribués tout en gardant des garanties
en termes de reproductibilité.
(use case: expérience sur G5K avec plusieurs nœuds et “rôles”)

However, these areas often require intensive research, expensive tools, and substantial long-term funding, without which their results may be limited. The EU-funded ODISSEE project will bring together the efforts of three pan-European ESFRI infrastructures in the physical sciences, alongside several other key sectors, to enhance European excellence and leadership in astronomy and high-energy physics. The project will provide access to essential high-quality hardware, software, R&D programmes and state-of-the-art experimental facilities to support key scientific projects and researchers, particularly those focused on the search for dark matter.

Title: On the Sharing of Cloud Computing Resources

Abstract:
Cloud Data Centers are central to the popular Cloud Computing
paradigm. While consolidating diverse workloads within large sites has
improved the overall energy efficiency of these facilities, one
significant challenge remains: low server utilization. This
underutilization can be considered a form of hardware waste, as many
servers are required relative to the actual demand. In this
presentation, we will explore how physical resources can be shared
among clients in an “oversubscribed” model, examining various
scheduling techniques, architectural strategies, and paradigms to
optimize resource usage.

Pierre Jacquet is a Cloud Computing researcher starting a postdoctoral
position at ÉTS Montréal. He earned a Master’s degree in Computer
Science from Université Paris XII in 2021 and recently completed his
Ph.D. at Inria Lille, between both the Spirals and Stack teams. His
research interests include resource scheduling and sustainable
computing.

Title:
Energy-Efficient Processing in Radio Astronomy: Comparative Analysis
of Computing platforms and their Implementation

Short abstract:
As the Square Kilometer Array pushes the limits of radio astronomy,
energy-efficient computing is crucial. My research firstly compares
the energy efficiency of Field-Programmable Gate Arrays (FPGAs) and
Graphics Processing Units (GPUs), two key technologies in this field,
and secondly investigates the effect of using the HDL coder
abstraction layer.

First, we ran a correlator algorithm on both platforms and found that
FPGAs processed 127 times more instructions per kilowatt-hour than
GPUs, indicating significantly better energy efficiency. Secondly, we
examined the impact of using HDL Coder  an abstraction tool for
programming FPGAs. We used the correlator algorithm, and found that
the abstraction layer increased power consumption by 11.18%.

These results suggest that while GPUs are being adopted, FPGAs may
still offer superior energy efficiency for certain tasks. Moreover,
abstraction tools, though useful, come with an energy cost.
