The Jupiter supercomputer, capable of at least one quintillion calculations per second with 24,000 Nvidia chips, is inaugurated in Jülich, North Rhine-Westphalia, Germany, marking Europe's first system considered internationally competitive in training artificial intelligence models. On a partial system test, Jupiter has achieved a preliminary 793.4 Petaflop/s, placing it 4th in the Top 500 behind El Capitan, Frontier, and Aurora at the US Department of Energy.
