Data centers have become an essential part of modern life, powering complex applications and enabling seamless connectivity. From internet searches and weather forecasts to online ordering, data centers play a crucial role. Scientific research, including data-intensive high-performance computing (HPC) and cloud computing, relies heavily on these facilities. The environmental impact of data center operations cannot be ignored, particularly in the context of energy consumption.

In many regions, the demand for computing and storage capacities surpasses available resources, necessitating an ecologically, economically, socially, and technologically conscious approach to development. Today, energy-efficient systems offer a viable solution to address this challenge, enabling the realization of more powerful and environmentally friendly data center infrastructures. By focusing on metrics such as performance per computing operation (Watts/FLOPS), energy efficiency can be significantly improved.

Efforts to optimize energy management in HPC data centers go beyond primary cooling solutions. Waste heat reuse and energy optimization are critical areas of focus. Real-time processing of sensor data using machine learning algorithms plays an increasingly significant role. Moreover, the regular replacement of hardware with more energy-efficient and powerful systems contributes to environmental impact through production and disposal.

Managing data centers efficiently requires complex optimization strategies to enhance resource usage and increase economic and environmental sustainability. Software plays a crucial role in these optimizations, as it controls energy-saving modes, data transfer, and computing operations. Container and workflow frameworks already enable more flexible and efficient hardware utilization, although their integration into supercomputing clusters is still in progress.

This workshop will explore various topics related to energy management in HPC data centers, including but not limited to:

  • Green Data Center IT and Software
  • Optimizing the energy efficiency of systems
  • Models for energy and resource efficiency assessment
  • Resource conservation through smart technologies and artificial intelligence
  • Real-time energy consumption prediction and regulation using machine learning
  • Efficient facility infrastructures and hybrid cooling technologies
  • Secondary use of waste heat and integrated community heating systems
  • Scalable, hybrid, and flexible compute and data system architectures
  • Container and workflow frameworks enabling energy efficiency methods
  • Green coding approaches in high-performance software
  • Scheduling algorithms for optimal energy use

Contributions that extend beyond these topics and align with the core theme of the workshop are particularly welcome. Join us to explore innovative approaches for achieving energy efficiency and sustainability in HPC data centers, paving the way for a greener and more efficient future.
