Ten Exaflop European Supercomputer in 2021

The European supercomputer Leonardo, managed by Cineca, that will be installed at the end of 2021 in the new data center located in Bologna, will be based on Atos BullSequana XH2000 technology, and feature nearly 14,000 NVIDIA Ampere architecture-based GPUs and NVIDIA Mellanox HDR InfiniBand. It will deliver 10 exaflops of FP16 AI performance.

It will be based on Atos BullSequana XH2000 technology and use 14,000 next generation NVIDIA Ampere architecture-based GPUs and NVIDIA Mellanox HDR InfiniBand.

Capable of an aggregated HPL performance of 250 Pflops (250 trillion operations per second) and equipped with over 100 petabytes of state-of-the-art storage capacity, the system will provide 10 times the computing power of Cineca’s current top tier system Marconi100, which is currently ranked in the ninth position on the global TOP500 list of the world’s most powerful supercomputers.

Leonardo is the first of three pre-exascale systems announced by EuroHPC, a collaboration between national governments and the European Union. Funded by the European Commission and by the Italian Ministry of Universities and Research, EuroHPC’s aim is to develop a world-class supercomputing ecosystem and exascale supercomputing in Europe. The other pre-exascale class systems, that will join the Italian Leonardo will be installed in Finland and Spain.

A 500 PetaFLOP Luxembourg-based MelaXina system will be used for financial services, manufacturing, and health care applications. It will connect 800 Nvidia A100 graphics cards on HDR 200Gbps InfiniBand links. The new Vega supercomputer at the Institute of Information Science in Maribor, Slovenia, it will include 240 A100 graphics cards and 1,800 HDR 200Gbps InfiniBand endpoints. The IT4Innovations National Supercomputing Center will host what’s expected to become the most powerful supercomputer in the Czech Republic. It will be an Apollo 6500-based system with 560 A100 graphics cards to deliver nearly 350 petaflops of performance for academic and industrial simulations, data analytics, and AI.

Technical Information
Leonardo will be built from Atos’ BullSequana XH2000 supercomputer nodes, each with four NVIDIA Tensor Core GPUs and a single Intel CPU. It will also use NVIDIA Mellanox HDR 200Gb/s InfiniBand connectivity, with smart in-network computing acceleration engines that enable extremely low latency and high data throughput to provide the highest AI and HPC application performance and scalability.

Leonardo will feature nearly 14 000 NVIDIA Ampere architecture-based GPUs. It will deliver 10 exaflops of FP16 AI performance. NVIDIA Ampere architecture GPUs can accelerate over 1,800 applications such as Quantum Espresso for material science, SPECFEM3D for geoscience and MILC for quantum physics by up to 70x, making previous big challenge simulations almost real-time tasks.

3rd Gen Intel Xeon Scalable processors (Ice Lake) are optimized to perform computationally intensive workloads in high-performance computing systems like Leonardo. The follow-on processor to Intel’s Ice Lake server processors is Sapphire Rapids, which will enable exascale computing with advanced built-in AI acceleration capabilities.
