It took shape, with sign the contract for its construction first European exascale supercomputercapable of touching 1 exaflop or, if you prefer, 1 billion billion calculations per second.JupiterIt is said that – at least in the initial phase – it will not include any components from Intel or AMD, be it x86 CPUs or accelerators, but rather will combine them togetherRhea processors from SiPearl – related to ARM architecture – with NVIDIA accelerator.
Jupiter will ask for it an expense of 273 million euros for its construction and Sar installed in the Jlich Supercomputing Centernear Munich, with construction starting in early 2024. The original budget for the system was 500 million euros, but it cost just over half, of which 50% was financed by the EuroHPC JU and the rest by the Federal Ministry of Education and Research Institute and Ministry of Culture and Science of the State of North Rhine-Westphalia.
The supercomputer Property of EuroHPC JU (European High-Performance Computing Joint Undertaking), the joint initiative that brings together Europe, European states and private partners to lead the Old Continent into the future of supercomputing. Eviden – part of the Atos Group – and ParTec will be responsible for the construction.
Jupiter will run classic computing applications and is also designed for artificial intelligence technologies, including simulations to accelerate the discovery of new drugs or simulating weather problems to make predictions or understand climate change.
Jupiter will be based on two main parts, a “booster module” with accelerators from NVIDIA – Hopper solutions are assumed, but we will see – and a “cluster module” with SiPearl Rhea processors (official name Rhea1) based on ARM’s Neoverse V1 architecture. The supercomputer was designed to be modular and allows various accelerators to be connected to the central system, while the processor supports HBM and DDR5 memory.
In short, if integrating x86 CPUs into the system is unlikely, future expansions of Jupiter could theoretically also introduce accelerators from AMD and Intel, with which SiPearl has been working for some time to support AMD Instinct and Intel Data Center GPU Max. Solutions are working (Old Bridge).
Europe is trying regain technological sovereignty has been ignored for too long in the past decades, and Jupiter is just the first of a series of exascale supercomputers to be born in the future.
A second project, for example, concerns the construction of an exascale supercomputer in Franceactive from the end of 2025. The system is managed by the Jules Verne consortium, which includes the French institutions GENCI (Grand Equipement National de Calcul Intensif), CEA (the Commission for Alternative Energies and Atomic Energy) and the Dutch supercomputing center SURF.
