Jupiter: Europe's largest supercomputer inaugurated in Germany

Europe's first supercomputer to reach the exascale class, Jupiter, was inaugurated on September 5 at a ceremony held in Julich, Germany.

Capable of performing more than a quintillion operations per second, the resource sets a new benchmark for computing capacity on the European continent. According to the June 2025 TOP500 list, the global benchmark for supercomputer rankings, Jupiter already ranks fourth globally and first in Europe.

Jupiter Booster, the accelerated partition of the supercomputer, is also already identified as the most powerful globally, according to the same list. On the other hand, among the five most powerful supercomputers in the world, Jupiter stands out as the most energy efficient.

The newly inaugurated supercomputer, like others such as Deucalion and Mare Nostrum 5, funded by the National Recovery and Resilience Plan, is designed to drive advances in key areas such as artificial intelligence, biotechnology, and climate change. Researchers, engineers, and entrepreneurs from across Europe—including Portugal—can apply for computing time through Calls opened by the EuroHPC Joint Undertaking (JU) initiative, available on its official portal. In Portugal, EuroCC Portugal supports teams interested in preparing proposals and accessing this world-class infrastructure.

This resource is part of a joint European effort coordinated by EuroHPC JU and was developed with financial support from the European Union, the German government, and the state of North Rhine-Westphalia.
