The brief
- JUPITER inaugurated September 2025; Europe's first exascale supercomputer, ranked 5th globally on TOP500 in June 2026.
- 24,000 NVIDIA GH200 superchips combined with SiPearl Rhea CPUs in hybrid GPU-CPU architecture.
- World's most efficient exascale system: 15 MW powered by renewables, waste heat feeds district heating.
Technical approach
GPU and CPU hybrid architecture
GPU-accelerated booster with ~6,000 nodes of NVIDIA GH200 superchips for AI and data work, plus CPU cluster with SiPearl Rhea for HPC simulations.
Renewable power and heat recovery
15 MW powered entirely by renewable energy. Waste heat captured for district heating across the campus, eliminating losses.
Four decades of HPC leadership
JSC operates some of Europe's most powerful systems, tracing its roots to 1987 and backed by Germany's Gauss Centre.
