Jupiter: Europe's largest supercomputer inaugurated in Germany

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

Capable of performing over a quintillion operations per second, the resource sets a new benchmark for computing power 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 supercomputer's accelerated partition, is also identified as the most powerful globally, according to the same list. Furthermore, 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 Portuguese ones—can apply for computing time through the public tenders opened by the EuroHPC Joint Undertaking (JU) initiative, available on its official portal . In Portugal, EuroCC Portugal supports teams interested in preparing proposals and gaining access to this world-class infrastructure.

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