Europe is one step closer to having its first exascale supercomputer, JUPITER, with the completion of its second module, JETI. This milestone marks a significant leap forward in high-performance computing, as JETI now ranks among the world’s most powerful supercomputers.
Built by the Franco-German team ParTec-Eviden, JUPITER will enable breakthroughs in artificial intelligence and take scientific simulations to new heights. The system is being installed at Forschungszentrum Jülich and will be operated by the Jülich Supercomputing Centre.
When complete, JUPITER will boast approximately 24,000 NVIDIA GH200 Grace Hopper Superchips, making it one of the world’s fastest systems for AI. The current JETI pilot system has already achieved a performance of 83 petaflops, doubling the performance of Germany’s current flagship supercomputer, JUWELS Booster.
Europe’s Quest for Exascale Computing: The JUPITER Supercomputer
The pursuit of exascale computing has reached a significant milestone with the completion of the JETI module, a crucial component of Europe’s first exascale supercomputer, JUPITER. Located at Forschungszentrum Jülich, JUPITER is poised to revolutionize artificial intelligence (AI) and scientific simulations, enabling breakthroughs in various fields.
The JUPITER Exascale Transition Instrument (JETI) has demonstrated remarkable performance, ranking among the world’s most powerful supercomputers. By doubling the performance of JUWELS Booster, currently Germany’s fastest supercomputer, JETI has set a new benchmark on the TOP500 list of the world’s fastest supercomputers. This achievement underscores Europe’s commitment to advancing high-performance computing and securing technological sovereignty.
Modular Design and Energy Efficiency
The JUPITER system is designed with modularity in mind, comprising multiple modules that can be easily scaled up or down depending on the specific requirements of users. The current JETI pilot system contains 10 racks, which is approximately 8% of the size of the full system. This modular approach enables flexibility and adaptability, allowing researchers to tackle complex problems with ease.
In addition to its impressive performance, JETI has demonstrated exceptional energy efficiency, securing a 6th position on the Green500 list of the most energy-efficient supercomputers. This result highlights the high standards set by JUPITER’s development system, JEDI, which was launched at Forschungszentrum Jülich earlier this year and topped the Green500 list.
Hardware and Performance
The final JUPITER system will be equipped with approximately 24,000 NVIDIA GH200 Grace Hopper Superchips, specifically optimized for computationally intensive simulations and AI model training. This configuration will enable JUPITER to achieve more than 70 ExaFLOP/s in lower-precision 8-bit calculations, making it one of the world’s fastest systems for AI.
In a trial run using the Linpack Benchmark for the TOP500 list, JETI achieved a performance of 83 petaflops, equivalent to 83 million billion operations per second. This remarkable performance has propelled JETI to the 18th position on the current TOP500 list of the world’s fastest supercomputers.
Funding and Partnerships
The development of JUPITER is a collaborative effort, with funding provided by the European supercomputing initiative EuroHPC Joint Undertaking (EuroHPC JU), the Federal Ministry of Education and Research (BMBF), and the Ministry of Culture and Science of the State of North Rhine-Westphalia (MKW NRW) via the Gauss Centre for Supercomputing (GCS). This partnership underscores the importance of international cooperation in advancing high-performance computing.
The JUPITER supercomputer is poised to become a driver of progress for Germany and Europe, contributing to securing technological and digital sovereignty. As one of the most powerful AI supercomputers in the world, JUPITER will enable breakthroughs in various fields, from climate modeling to materials science, and cement Europe’s position as a leader in high-performance computing.
