Closing Day 1 and Welcome Reception

Title: Sustainable Wireless Networks for Solar Energy Fields

Abstract: This keynote presents a transformative wireless communication system designed to address the unique challenges of Concentrated Solar Power (CSP) fields. Built on the principles of Integrated Access and Backhaul (IAB) technology, adaptive routing, and dynamic spectrum management, this fully autonomous system enables real-time, energy-efficient communication across large-scale solar infrastructures. By incorporating modular network design, intelligent clustering, and interference mitigation strategies, the system ensures robust performance while minimizing latency and energy consumption. Extensive simulations and emulations in a CSP environment with over 7,800 solar reflectors demonstrate the system’s ability to achieve end-to-end communication latencies of less than 250 milliseconds, a critical requirement for precise reflector calibration and control. These results highlight the system’s potential to enhance operational efficiency and sustainability in CSP fields, while its underlying principles offer broader applications for green and sustainable networking in other energy-intensive domains. This talk will explore the system’s design, implementation, and performance, offering insights into how advanced wireless technologies can drive the future of renewable energy and sustainable networking. Join us as we delve into the intersection of innovation and sustainability, shaping a greener future for global energy systems.

Title: Can we make HPC green?

Abstract: High-performance computing used to require a large amount of electrical power to operate efficiently. However, power consumption has become a major concern. For instance, the US DoE's roadmap towards exascale targetted 20MW as an upper limit for the first exascale machine. The Green500 ranks supercomputers based on their performance per Watt and gets growing attention from vendors and users. In this talk, I will present how the power consumption of HPC can be modeled and evaluated.

She obtained a PhD from University Paris Sud in 2009. Her interests focus on how scientific applications can best utilize high-performance computing, and how the run-time environment can support the execution of scientific applications.

How much energy quantum computers would consume : could this be a threat to their scalability, or, on the contrary, could we hope for a quantum energy advantage ?

Panel Moderator: Marco Fellous Asiani

Panel Organizer: Hesham ElBakoury 

Panel Abstract: Quantum computers bring the promise to solve calculations that would be out of reach of the best supercomputers available. However, the question of their energy consumption is usually left aside. 

In this panel, we will explore whether energy requirements could pose a fundamental bottleneck to the large-scale deployment of quantum computers. Conversely, we will discuss whether quantum computers could offer an energy advantage compared to classical supercomputers. Finally, we will discuss what are the main sources of energy consumption inside common types of quantum computers, and consider the different strategies for improving the energy efficiency of quantum computing architectures, highlighting the key challenges and opportunities in this area.
