In 2022, the Leonardo supercomputer was inaugurated in Bologna, Italy. First announced in 2020, this €120 million ($124.5 million) system immediately ranked as the fourth most powerful on the Top500 list published in November 2022.
The machine is an Atos BullSequana XH2000 system, featuring Xeon Platinum processors and Nvidia A100 GPU accelerators. It offers a sustained Linpack performance of 174.7 petaflops and a peak performance of 255.75 petaflops.
The supercomputer is housed at CINECA, a consortium of 112 Italian universities and public institutions that provides High Performance Computing (HPC) resources to its members. Leonardo was expected to become fully operational in the first half of 2023 with an anticipated performance of 250 petaflops.
