The exascale partition of the Jupiter supercomputer has today (September 5) been inaugurated at the Jülich Supercomputing Centre (JSC) in North Rhine-Westphalia, Germany.

Once the partition goes live, the Eviden-designed BullSequana XH3000 system will become Europe’s first exascale system. Currently, it offers a total of 793.4 petaflops and is the fourth most powerful supercomputer on the Top500 list.

Procured by the EuroHPC JU initiative, Jupiter is housed in a modular data center at JSC, comprising 50 pre-built, interchangeable modules, which the center says is the equivalent of around half a soccer pitch in size. Atos-owned Eviden is also responsible for building the modular data center.

The system itself contains 24,000 Nvidia GH200 Grace Hopper Superchips, cooled by Eviden’s direct liquid cooling technology and interconnected with Nvidia Quantum-2 InfiniBand networking. According to the company, Jupiter has demonstrated “unrivaled energy efficiency,” with the system’s first module – dubbed JEDI – ranking first on the Green500 list of most efficient supercomputers.

Use cases for Jupiter will include weather forecasting and climate simulation, AI model training, and neural network mapping.

Earlier this year, DCD visited the Hunter supercomputer at the High-Performance Computing Center (HLRS) in Stuttgart, Germany. You can read about it in the upcoming issue of the DCD Magazine. Register here.
