Helmholtz Information Achieves Top Rankings in the Green500 for Energy-Efficient Supercomputers
Helmholtz Information sets new standards in energy efficiency and computational performance. The Forschungszentrum Jülich (FZJ) and the Karlsruhe Institute of Technology (KIT) have recently achieved significant successes in the Green500 ranking of the most energy-efficient supercomputers.
With increasing digitalization and the use of artificial intelligence, the demand for powerful and energy-efficient data centers is rising. In Germany, data centers already account for nearly 4 percent of total electricity consumption, and this share is growing. Helmholtz Information addresses this challenge with innovative technologies to reduce energy consumption and maximize computational performance.
JUPITER: Top Spot for Jülich’s Exascale Supercomputer
The first module of the European Exascale Supercomputer JUPITER, called JEDI, has secured the top position in the Green500 list. JUPITER, developed by the Forschungszentrum Jülich in cooperation with the EuroHPC Joint Undertaking and the ParTec-Eviden consortium, achieves an impressive 72 billion calculations per second per watt. This is a significant leap from the previous leader, which reached around 65 billion calculations per second per watt.
The success of JEDI is based on the use of the latest NVIDIA GH200 Grace Hopper Superchips, which combine GPUs and CPUs. This architecture enables high energy efficiency and powerful computations. Additionally, an efficient warm water cooling system helps reduce energy consumption and allows for the reuse of waste heat to heat buildings on the Forschungszentrum Jülich campus.

HoreKa: KIT Achieves Top Ranking in Green500
The Karlsruhe Institute of Technology (KIT) has also achieved remarkable success. The “High-Performance Computer Karlsruhe” (HoreKa) now ranks sixth in the Green500 list following a recent upgrade. This improvement by seven places since 2021 demonstrates KIT’s commitment to energy efficiency and sustainability.
HoreKa, a hybrid system consisting of 668 accelerators and 60,000 standard processors, was enhanced with 88 new NVIDIA H100 accelerators. These new components increase HoreKa’s total performance to over 20 petaFLOPS, equivalent to more than 20 quadrillion calculations per second. The high energy efficiency of 63 gigaFLOPS per watt was achieved through hardware optimizations and adjustments to the maximum power consumption of the accelerators.
Future Prospects and Sustainability
The successes of JUPITER and HoreKa highlight Helmholtz Information’s commitment to sustainable and efficient high-performance computing. By combining cutting-edge technology with innovative cooling methods, these systems not only contribute to leading-edge scientific research but also set new standards in energy efficiency.
Helmholtz Information plays a central role in these developments by bringing together leading experts and the latest technologies to push the boundaries of supercomputing research. These advancements demonstrate Helmholtz Information’s ability to foster groundbreaking scientific and technological progress while developing sustainable solutions for future challenges.
