Germany has inaugurated JUPITER, Europe's most powerful AI supercomputer at the Jülich Supercomputing Centre. Powered by NVIDIA Grace Hopper Superchips and Quantum-2 InfiniBand networking, it's the first exascale machine outside the US. The system combines high-performance computing with AI to accelerate research in climate modeling, quantum physics, energy, and material design. Chancellor Friedrich Merz called it "a historic European pioneering project" that will serve numerous German and European research teams, opening new possibilities for science and industry across the continent.
