Energy efficient data centres

Over the last 5 decades, a wide range of different computing platforms have been developed, establishing themselves for several applications. Most require specific data centre architectures to optimize their operation for improved resource efficiency or comprehensive environmental sustainability. Research and innovation on data centers intend to combine specific computer systems and their incumbent infrastructure (such as cooling systems and connection to the power grid) with novel algorithms in ways that can solve the many challenging problems. Innovation potential lies in the computer systems, their architecturesand infrastructure, the algorithms, and requirements (namely, efficiency, sustainability, security, sovereignty, robustness, and more).

12th International Workshop on The ever-evolving data centers: research and innovation (E2DC 2024)

There are two themes that deserve special attention within this workshop. First, the phenomenal growth of AI applications has pushed HPC computing towards the mainstream. The increased challenges for the data centre infrastructure are leading to a broader interest in advanced architectures and technologies such as liquid cooling techniques. Second, is the growing needs for innovative techniques and solutions for data centres located in environmentally challenging locations.
