HLRS unveils details about the upcoming supercomputer "Herder"

December 2, 2025

The new supercomputer "Herder" at the University of Stuttgart’s High-Performance Computing Center (HLRS) is intended to advance basic research, support industry in product development, and assist the public sector in addressing global challenges.

HLRS has announced the architecture of its upcoming supercomputer "Herder," which is being developed in collaboration with technology partners Hewlett Packard Enterprise (HPE) and Advanced Micro Devices (AMD). The new system is expected to be significantly more powerful than its predecessor and to offer an optimized configuration for state-of-the-art computing applications. This is intended to provide German and European research as well as industry with a new, powerful tool for scientific insights and industrial innovation.

Powerful, efficient, and sustainable

"͵Herderʹ  will be a key element of supercomputing infrastructure in Stuttgart. It is powerful, highly efficient, and at the same time conserves resources. Not only our top researchers benefit from this, but the entire innovation ecosystem of our university,” explained Anna Steiger, Chancellor at the University of Stuttgart, during the signing of the contract for the configuration of the computer and the cooperation with HPE and AMD.

“Herder" is expected to be more than seven times faster than the current system "Hunter" and, once operational, it will rank among the most advanced high-performance computers in the world. It is intended to be used for research purposes across a wide range of disciplines, including computer science, engineering, physics, chemistry, climate science, and biomedicine. Herder is scheduled to be delivered in the second half of 2027 and then prepared for operation.

After signing the contract: Antonio Neri (President & CEO HPE), Anna Steiger (Chancellor at the University of Stuttgart), Michael Resch (Director of HLRS), Marc Fischer (Managing Director and Vice President Global Sales HPE Germany).

Decarbonization and Economic Efficiency

The system will be housed in a new building (HLRS III), currently under construction on Campus Vaihingen at the University of Stuttgart, and designed with sustainability in mind. It is also planned that HLRS III will be connected to a new power plant and a waste heat utilization facility, capturing the waste heat generated by "Herder" and distributing it to other buildings on the campus. This is intended to help the university save energy and reduce CO2 emissions by around 50 percent – a significant contribution to reducing carbon emissions on campus.
