Europe’s very first exascale supercomputer will be launched in Germany next year
JUPITER will be the first European supercomputer to make the leap to the exascale era. This means it will be able to perform more than an exaflop (or 1 trillion) operations per second. In other words, the computing power of the device will pass by that of 5 million laptops or PCs combined.
The European High Performance Computing Joint Undertaking (Euro HPC JU), who is behind the project, has now signed a hosting agreement with the Julich Supercomputing Center (JSC) in Germany, where JUPITER will be located.
Under the terms of the agreement, JUPITER (which stands for “Joint Undertaking Pioneer for Innovative and Transformative Exascale Research”) will be installed on the campus of the research institute Forschungszentrum Jülich in 2023. The machine will be operated by the JSC.

This new supercomputer will be supported by a budget of €500 million, divided equally between the EuroHPC JU and German federal and state sources.

An important technological milestone for Europe
JUPITER’s remarkable power will support the development of highly accurate models of complex systems. The machine will be used to analyze key societal issues in Europe, such as health, biology, climate, energy, security and materials. It also supports intensive use of AI and analysis of huge data volumes.
Experts expects the computer to improve research quality (while reducing costs), and integrate future technologies such as quantum computing. The device will be available to a wide range of European users in the scientific community, industry and the public sector.
Together with its excellent computational power, JUPITER will have a dynamic, modular architecture that will take full advantage of the various computational modules used during complex simulations. Notably, JUPITER is designed as a “green” supercomputer and will be powered by green electricity backed up by a hot water cooling system. At the same time, the average power consumption is expected to reach 15 megawatts – about six megawatts less than the US Border exascale supercomputer.
Upon completion, JUPITER will be the ninth (and best) supercomputer EuroHPC JU has delivered to Europe. Three are expected to be available soon and five are already operational. is among them LUMIwhat has been arranged the fastest in the EU and the third fastest in the world.
