Supercomputers, Europe enters the exascale era with the German Jupiter Booster. Italy in the G4
With 18 supercomputers in the Top500, Italy remains the fourth most powerful country in the world in terms of installed computing power, after the United States, Japan and Germany. The first Italian supercomputer in the ranking is Eni's Hpc6, which is currently the sixth most powerful supercomputer in the world and second most powerful in Europe
Key points
In the global race for supercomputing, in which the United States is still ahead, Europe has reached an important milestone. The German Jupiter Booster supercomputer is officially Europe's first exascale-class computing system. Installed at the EuroHPC/Jülich Supercomputing Centre in Germany, it reached a computing power of 1,012 exaflops per second after a period of fine-tuning, as certified by the 66th edition of the TOP500, the ranking of the world's most powerful supercomputers, just announced at the SC25 conference in St. Louis, Missouri.
Based on Eviden's BullSequana XH3000 architecture with direct liquid cooling and Nvidia Grace Hopper superchip, Jupiter Booster is the fourth exascale system in the world and the first outside the US.

In fact, there are currently only four exascale-class supercomputers certified by the Top500 ranking, which also confirms the wide spread of pre-exascale machines worldwide.
What is Exascale Calculus
A supercomputer is said to be of exascale class if it is capable of performing at least one exaflop of floating-point operations per second. That is, a quintillion calculations per second. The advantages of exascale computing concern the ability to solve unsolvable problems. For example, exascale computing offers the power needed to establish the origins of chemical elements, developing new processors, controlling unstable substances and materials, validating thelaws of nature and solving particle physics.
Supercomputing: United States in the lead
The new edition of the rankings confirms the United States' leadership in high-performance computing. The El Capitan supercomputer installed at the Lawrence Livermore National Laboratory (LLNL) remains the undisputed leader, recording a new peak power of 1.8 exaflops of operations per second. The other two supercomputers making up the Top500 podium are also American: Frontier and Aurora.
