ISC High Performance: Conference, exhibition and programm

The International Supercomputing Conference (ISC High Performance) will take place from June 10 to 13, 2025 in Hamburg. Under the motto "Connecting the Dots," up to 3,500 leading players from science, industry, and research are expected to present the latest developments in HPC and AI, data analysis, storage, networking, and quantum computing, discuss them together, and network with each other.

On June 11, 2025, climate researcher Prof. Dr. Bjorn Stevens from the Max Planck Institute for Meteorology will give the midweek keynote on the topic "The New Landscape of Climate Computing". He will discuss how AI, HPC, and new modeling approaches can be used to address the most pressing challenges in climate research.

In the exhibition, which takes place parallel to the conference, 195 hardware and software vendors, service providers, and 51 research institutions from 31 countries present their work, services and products – including the Gauss Alliance (GA). As a member, the DKRZ will be presenting the latest climate simulations calculated on the Levante supercomputer at the GA booth (photo on the right).

Directly adjacent, the National High-Performance Computing Center (NHR) is organizing so-called Sofa Talks. In the discussion "Connecting Visualization and High-Performance Computing," Michael Böttinger, a visualization expert at the DKRZ, discussed challenges and trends related to visualization in HPC environments with 12 other international experts.

An originally from the US company AMD initiated Birds-of-a-Feather session titled "Empowering Excellence in HPC Through Diversity and Inclusion," which featured Dr. Georgiana Mania as one of eight speakers, was canceled at short notice. 

New Top 500 list published at ISC '25

The new edition of the Top 500 list of the world's most powerful supercomputers was presented at the ISC in Hamburg on June 10, 2025. The list continues to be led by the US system El Capitan, which maintains its top spot with a computing power of 1,742 ExaFLOPS. Frontier and Aurora, also Exascale systems, follow in second and third place. All three supercomputers are operated at the Lawrence Livermore National Laboratory of the US Department of Energy.

JUPITER, a system operated at the Jülich Research Center (FZJ), takes fourth rank on the list with a performance of over 790 PetaFLOPS. JUPITER is not only the fastest system in Germany and Europe, but is also one of the most energy-efficient supercomputers in the world.

Almost four years after its installation, the DKRZ supercomputer Levante still ranks 140th. This makes Levante one of the eleven most powerful systems in Germany.

Student Cluster Competition (SCC)

During the ISC, students have the opportunity to demonstrate their knowledge and skills in the Student Cluster Competition (SCC). This year, the DKRZ is once again contributing to the successful implementation: Firstly, it created the tasks using the ICON weather and climate model for the online programming portion (Coding Challenge) and is providing four GPU nodes on its Levante HPC system for this purpose. Secondly, two judges from the DKRZ will be responsible for evaluating the SCC.
