LEONARDO
The new pre-exascale Tier-0 EuroHPC supercomputer
The pre-exascale Tier-0 EuroHPC supercomputer LEONARDO is classified in 6° position among the most powerful supercomputers in the Top500 List. It is hosted by Cineca and is currently built in the Bologna Technopole. It is supplied by ATOS, with two main partitions: Booster Module and Data-centric Module. The booster module partition is based on BullSequana XH2135 supercomputer nodes, each with four NVIDIA Tensor Core GPUs and a single Intel CPU. It also uses 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. The Data-centric partition is based on BullSequana X2140 three-node CPU Blade and is equipped with two Intel Sapphire Rapids CPUs, each with 56 cores.
