Germany to host Europe’s first exascale supercomputer • The Register

Germany will host Europe’s first publicly known exascale supercomputer, along with four other EU sites becoming smaller but still powerful systems, the European Joint Undertaking for High-Performance Computing (EuroHPC JU) announced this week. .

Germany will host Jupiter, the “Joint Undertaking Pioneer for Innovative and Transformative Exascale Research”. It is expected to go live next year in a purpose-built building on the campus of the Forschungszentrum Jülich research center and operated by the Jülich Supercomputing Center (JSC), alongside existing Juwels and Jureca supercomputers.

The four midrange systems are: Daedalus, hosted by the National Research and Technology Infrastructures in Greece; Levente at the Government Agency for IT Development in Hungary; Caspir at the National University of Ireland Galway in Ireland; and EHPCPL at the CYFRONET Academic Computing Center in Poland.

According to EuroHPC, Jupiter will be used to help solve important scientific problems such as climate change, the fight against pandemics and the production of sustainable energy. It is also intended to enable applications involving artificial intelligence and the analysis of large volumes of data.

Reaching the level of exascale is the next big step in the field of high-performance computing, said Professor Dr Astrid Lambrecht, from the board of the Forschungszentrum Jülich.

“Our goal is to offer the most powerful infrastructure in Europe that combines neuromorphic computing, supercomputing and quantum computing, ensuring that diverse user groups from science and industry can learn and grow. together while benefiting each other,” she said.

Half of the €500m (approximately $520m or £430m) funding for Jupiter comes from the EuroHPC JU programme, the other half will be provided by the German Federal Ministry of Education and Research (BMBF) and the Ministry of Culture and Science of the State of North Rhine-Westphalia (MKW NRW), where the Forschungszentrum Jülich is located.

Jupiter will be based on a dynamic and modular supercomputing architecture, which has already been used for the Juwels supercomputer. This apparently allowed the Juwels system to be upgraded in 2020 so that the CPU-based cluster module is paired with a GPU-equipped booster module. Both modules were based on Atos BullSequana X hardware.

With Jupiter, the base configuration will include a universal cluster module and GPU accelerators, as well as a high-capacity parallel storage module, high-bandwidth flash storage, and a high-capacity backup and archive configuration.

Optional units in the configuration are another GPU booster and an interactive computation and visualization module, while future modules could include a quantum processing unit and a neuromorphic processing module.

Jupiter was also apparently designed as a “green” supercomputer and will be powered by green energy, according to Forschungszentrum Jülich. It is also planned that Jupiter’s cooling system will be connected to the campus’ new low-temperature network so that the waste heat generated can be reused.

If this sounds familiar, it’s because the LUMI supercomputer announced by EuroHPC earlier this week in Finland is also powered by green energy and uses the waste heat it generates to help heat nearby homes.

The final decision to install Europe’s first exascale computer at the Forschungszentrum Jülich was apparently taken at the inauguration of the LUMI system.

Exact specs for Jupiter were not disclosed, but the exascale Frontier and LUMI system were built with HPE Cray EX hardware, using AMD Epyc processors and MI250X GPU accelerators, with nodes linked using HPE Slingshot Interconnect.

The Forschungszentrum Jülich is also becoming something of a supercomputing hub, since since March it has housed the German QSolid project which aims to develop a complete quantum computing system using local technology. ®
