Jupiter is the latest EU Supercomputer, for researchers, industry and AI development.

Europe has already developed a world-leading public supercomputing network by investing together with several Member States. Supercomputing is key to processing and analysing the ever-increasing volume of data in the world, and to making the most of it for the benefit of EU citizens, businesses, researchers and public administrations. Today Europe has 3 supercomputing in world’s top 10. The DIGITAL Europe programme is now also investing to acquire JUPITER - the first European exascale supercomputer. This will put an unprecedented amount of computing power at the disposal of Europe’s researchers, and industry as well as provide a huge boost to EU’s AI ecosystem.
Main Facts
EU co-funding
€ 250 million
Computing power
One billion billion calculations per second.
Partnership with Forschungszentrum Jülich
#1 energy-efficient supercomputer in the world
Jupiter in a nutshell
JUPITER will contain high-powered, energy efficient processors, including also first prototypes of ‘made in the EU’ processors – thanks to the European Processor Initiative. Its computing power will support the development of high-precision models of complex systems and applications:
- training large language models in AI
- running simulations for better, stronger, lighter materials
- creating digital twins of the human heart or brain for medical purposes
- complex climate simulations that take into account all of Earth’s systems
Future developments
After its installation in the second half of 2024, JUPITER will be made available to the scientific community, industries, and the public sector across Europe. Hundreds of applications will be run in areas such as climate change and weather forecasting, material science, bio-engineering, and training large language models. Jupiter will be accessible to startups across Europe to train and deploy generative AI models.
Impact

Once operational JUPITER joins the existing supercomputers of the EuroHPC JU already in operation: MareNostrum in Spain, LEONARDO in Italy, LUMI in Finland, Discoverer in Bulgaria, MeluXina in Luxembourg, Vega in Slovenia, Karolina in Czechia, and Deucalion in Portugal – all combining to put a total of almost two billion billion calculations per second, thus confirming Europe as a world supercomputing power.

Testimonial

“I am particularly proud that our specialists at Jülich, together with many European partners, succeeded in developing the new modular supercomputing concept, which is now the basis of JUPITER. This is a genuine European technology. Only thanks to the generous support of the European Commission and later EuroHPC JU… is such an investment possible.”
Prof. Thomas Lippert, Director of the JSC, Forschungszentrum Jülich

The Digital Europe Programme (DIGITAL) is an EU programme aimed at integrating digital technology into businesses, public services, and everyday life.
It targets six areas: high-performance computing, AI, cybersecurity, digital skills, widespread digital adoption, and semiconductors. DIGITAL acquires digital technologies, partners with European entities to create practical solutions, and provides outcomes that boost Europe's digital independence and competitiveness.
