The High-Performance Computing Center Stuttgart (HLRS) today announced the architecture of HLRS's upcoming next-generation supercomputer, developed with its technology partners, HPE and AMD. The new system—called Herder—will offer both a major increase in performance and an optimized architecture for today's most advanced computational applications, giving German and European research and industry a powerful new tool for scientific discovery and industrial innovation.

Herder will be based on the HPE Cray Supercomputing GX5000 system. Announced by HPE in November 2025, it is designed to support the large-scale numerical simulations that are essential within HLRS's traditional user communities, as well as data-science approaches for AI model training and generative AI. Bringing these capabilities together within a single system enables the development of new kinds of converged computing workflows that seamlessly integrate the two approaches.
