JSC @ ISC High Performance '26

The Arrival of Exascale in Europe

JSC@ISC High Performance '25 — The JSC team at ISC 2025

JSC at the ISC High Performance 2026 conference – 22 to 26 June, Hamburg, Germany

As in the previous year, the JSC will be present with two exhibition stands:

Booth #Z01, run by JSC, is once more dedicated to the new exascale supercomputer JUPITER, showcasing JSC's extensive supercomputing activities. Booth #K02, run by GCS, showcases the joint activities of the German partners within the Gauss Centre for Supercomputing (GCS). Alongside JSC, these include the High-Performance Computing Center Stuttgart (HLRS) and the Leibniz Supercomputing Centre (LRZ).

Our focus topics at JSC will be the immense potential of the JUPITER exascale supercomputer, our quantum machines, the integration of quantum and HPC systems, and technical and scientific developments, for example in the field of artificial intelligence.

At the JUPITER booth (#Z02), our most striking attraction continues to be Europe’s first exascale supercomputer JUPITER, developed and hosted by JSC. On a video wall, visitors will learn about scientific flagship projects already profiting from its exascale power.

Our unique original LEGO exhibits will also be on display again: Models of JUPITER and the Modular Data Centre (MDC) including the innovative cooling system on the roof – as well as a blade of the JUPITER Booster.

In addition, we will be showing videos of JUPITER and the JUPITER AI Factory (JAIF). As in previous years, our proven monitoring tool LLview will provide live insight into the computing jobs running on our systems.

At the GCS booth #K02, we will showcase the growing Jülich UNified Infrastructure for Quantum computing (JUNIQ), including live access at the booth, giving visitors a glimpse of its potential. Moreover, we will illustrate the steadily increasing importance of AI in HPC, as reflected in developments such as the Helmholtz AI Cooperation Unit. On top of that, parts of the new LEGO model of JUNIQ as well as an D-Dave Chip will be on display.

Numerous JSC contributions: talks, tutorials, and workshops

JSC researchers once again contribute extensively to the ISC programme in 2026: Andreas Herten organises the tutorial “Efficient Distributed GPU Programming for Exascale”, while Sebastian Achilles leads the tutorial “Introduction to EESSI: the European Environment for Scientific Software Installations” and also co-organises the corresponding Birds-of-a-Feather session later during the conference week. Brian J. N. Wylie contributes to the “3rd International Workshop on Readiness of HPC Extreme-scaling Applications”.

Estela Suarez plays a key role, contributing to sessions on advanced memory architectures and co-designing next-generation supercomputing systems, as well as participating in community activities at the conference.

The JSC directors Thomas Lippert and Kristel Michielsen are prominently represented throughout the conference programme. Kristel Michielsen contributes to the Birds-of-a-Feather session “Quantum-Computing-as-a-Service: What Do Users Want Today and How Can One Provide It?” and presents the projects “QEX & QEC4QEA” at the EuroHPC JU booth, while Thomas Lippert joins the NHR Sofa Talk on teaching with quantum computers.

JSC colleagues contribute to several Birds-of-a-Feather (BoF) sessions on European HPC strategies, AI ecosystems, dynamic resource usage, user support in the AI and exascale era, and future workforce development in quantum technologies, including Benedikt von St. Vieth’s BoF on “Deploying Next-Generation HPC Systems with NVIDIA Superchips: Early Experiences, Challenges, and Best Practices”, Mathis Bode’s session on “A European HPC Ecosystem for AI: Challenges and Opportunities”, as well as the user-focused BoF by Thomas Breuer and Ilya Zhukov on “Rethinking HPC User Support for the AI and Exascale Era”.

In the ISC Poster Sessions, JSC researchers share their contributions on continuous benchmarking from HPC clusters to quantum processors, the JUNIQ Benchmark Suite for quantum technology readiness, and advances in large-scale density functional theory. Further contributions are “The JUPITER AI Factory”, highlighting ongoing developments in Europe’s exascale and AI infrastructure, as well as the “JUNIQ Benchmark Suite” poster by Ashwin Kumar Karnad, which focuses on tracking quantum technology readiness within the JUNIQ infrastructure.

JSC is also strongly represented at the EuroHPC JU stand, where colleagues contribute to numerous presentations on European HPC, AI and quantum-computing projects, such as HPCQS, SYNERGYS, or EPICURE. In “JUPITER, exascale supercomputer & JUPITER AI Factory”, Benedikt von St. Vieth and Mathis Bode highlight JSC’s key role in the Europe’s AI factory initiative.
