Europe's first exascale supercomputer is massive, yet efficient

"To be clear, one exaflop of computing power means that one billion billion or quintillion calculations per second are possible. JUPITER ranks fourth in the world in the supercomputer rankings. As mentioned, this massive computing power is not the only trademark of this supercomputer in Jülich, Germany. According to the Green500 ranking, JUPITER ranks first in terms of energy efficiency. The so-called Booster partition of Evidens' computer scores 63 gigaflops per watt, a record in this class of computing power."

"For Evidens, this claim of efficiency is nothing new. It now holds the top three positions in the Green500 for the fourth time in a row. KAIROS (CALMIP) ranks number one with 73 GFlops per watt, followed by ROMEO (URCA) with 70 GFlops per watt and the Levante GPU extension (DKRZ) with 69 GFlops per watt. The company says that its energy efficiency is the result of years of focus on that specific goal."

"JUPITER forms the core of the JUPITER AI Factory, which will soon offer secure access to AI models for research, start-ups, and industry. Europe's first exascale system Eviden, the Atos Group division responsible for the construction, placed a total of 58 systems in the TOP500 list. JUPITER was developed by the Jülich Supercomputing Centre (JSC) in collaboration with the EuroHPC Joint Undertaking. The modular data center in which the supercomputer runs covers 2,300 square meters."

JUPITER achieves exascale computing with one exaflop, capable of a quintillion calculations per second, and ranks fourth in global supercomputer listings. The Booster partition records 63 gigaflops per watt, placing JUPITER first on the Green500 for energy efficiency. Eviden holds the top three Green500 positions repeatedly, with KAIROS, ROMEO, and Levante also posting high GFlops-per-watt figures. Efficiency stems from a fifth-generation patented direct liquid cooling solution and real-time energy-optimizing software such as Argos. JUPITER anchors the JUPITER AI Factory to provide secure AI model access and was developed by Jülich Supercomputing Centre with EuroHPC in a 2,300 m² modular data center.
