The first European next-generation supercomputer to be installed in 2023 is to be operated by: Forschungszentrum Jülich – a partner in the German Gauss Center for Supercomputing

The computer, called JUPITER (short for “Joint Undertaking Pioneer for Innovative and Transformative Exascale Research”), will be installed in a specially designed building on the campus of Forschungszentrum Jülich.

The system is planned to be managed by the Jülich Supercomputing Center (JSC), whose JUWELS and JURECA supercomputers are currently among the most powerful in the world.

The first supercomputer of the Exascale class

JUPITER is now poised to become the first European supercomputer to make the leap to the exascale class, with computing power more powerful than 5 million modern laptops or PCs.

JUPITER will be based on a dynamic, modular supercomputing architecture, which Forschungszentrum Jülich has developed together with European and international partners in the EU. DEEP research projects

For a modular supercomputer, different calculation modules are linked together, so that program parts of complex simulations can be distributed over several modules, so that the different hardware properties can be used optimally.

JUPITER’s modular construction also means that the system is well prepared to integrate future technologies like quantum computing or neuromorphic modules, which mimic the neural structure of a biological brain.

According to researchers, the JUPITER computer in its basic configuration will have a hugely powerful booster module with highly efficient GPU-based compute accelerators. Massively parallel applications are accelerated by this booster in a similar way to a turbocharger, for example to calculate high-resolution climate models, develop new materials, simulate complex cell processes and energy systems, advance fundamental research or train the next generation of computationally intensive algorithms. for machine learning.

Solving Energy Challenges

The average power of the supercomputer is estimated at a maximum of 15 megawatts. The exascale class supercomputer is designed as a “green” supercomputer and will be powered by green power. The intended hot water cooling system should help JUPITER achieve the highest efficiency values.

At the same time, cooling technology opens up the possibility of intelligently utilizing the residual heat produced. Like its predecessor JUWELS, for example, JUPITER will be connected to the new low-temperature network at the Forschungszentrum Jülich campus. Further possible applications for the JUPITER waste heat is currently being investigated by Forschungszentrum Jülich.
