Overview
- Top500’s November 2025 list records Jupiter at exactly 1.0 exaflops after the Booster’s full build-out, establishing Europe’s first exascale machine.
- Jupiter places fourth globally behind El Capitan at about 1.809 exaflops, followed by Frontier and Aurora.
- The Booster incorporates roughly 24,000 Nvidia GH200 Grace Hopper chips, with Nvidia technology providing both CPU and GPU acceleration.
- Measured at 63.3 gigaflops per watt, the system is reported among the most energy-efficient in the exascale class.
- Operated by Forschungszentrum Jülich under the EuroHPC program, the roughly €500 million installation targets climate, energy, medical and materials research.
