Europe's first exascale supercomputer ``Jupiter'' revealed to run on Arm core instead of x86

It has been revealed that the supercomputer ``

Jupiter '' scheduled to operate at Germany's Jülich Research Center is the first exascale computer to use Arm architecture instead of x86 .

EU Grabs ARM for First ExaFLOP Supercomputer, x86 Misses Out

An exascale computer is a supercomputer that can perform more than ¹⁰ floating point operations per second, or 1 EFLOPS (exaflops). It is believed that exascale computers will enable further applications and improved predictions in the fields of computer engineering such as weather forecasting and personalized medicine, but even the world's top 500 supercomputers do not have systems that operate at more than 1 exaflop. Very little.

Jupiter, a project led by the European High Performance Computing Joint Venture (EuroHPC JU), is said to be Europe's first exascale computer and will be launched at the Jülich Research Center in Munich, Germany, starting in early 2024. Assembly is scheduled to begin.

EuroHPC JU chose to install SiPearl 's Rhea processor, which is based on the Arm architecture, for Jupiter. However, only one of the world's top 10 supercomputers is based on the Arm architecture, and most are powered by x86 chips.

Arm-based chips were initially installed in many mobile devices such as smartphones. The Rhea processor, on the other hand, has 72 cores and is based on Arm's

Neoverse V1 CPU design, developed for high performance computing (HPC) applications. In addition, the Rhea processor supports HBM2E and DDR5 , which are high-bandwidth memories for HPC, and the cache can reach up to 160MB.

In addition, Jupiter will be equipped with a booster module that integrates NVIDIA's GPU and Mellanox 's ultra-wideband interconnect. Please note that NVIDIA has not revealed which GPU will be installed in Jupiter.

Foreign media Extreme Tech says, ``The current top supercomputer performance in 2023 is Frontier , which is installed at Oak Ridge National Laboratory in the United States, and its maximum performance is over 1.5 exaflops.The highest performance is 1.1 exaflops. When Jupiter, which can demonstrate the same performance, is completed, we plan to create a supercomputer comparable to Frontier.'
