TheEuroHPCsystem, the supercomputer LEONARDO hosted and managed by Cineca, is confirmed as the second most powerful supercomputer in Europe and is now in the 6th position on the Top500 list of the most powerful supercomputers in the world.

The announcement was made during the first day of the SC23, the most important international High Performance Computing conference, in Denver, Colorado.

With an HPL performance of 238.7 petaflops and a peak performance of 304.47 petaflops, Leonardo’s exceptional computing capabilities meet the diverse needs of European users and researchers in all scientific fields, from medicine to agriculture and many others.

This milestone rewards CINECA’s almost 60 years of commitment to supporting research through High Performance Computing and confirms Italy’s role as a strategic asset in building the European HPC ecosystem.


Leonardo maintains its status as Europe’s preeminent high-performance computing resource. Based on Eviden’s BullSequana XH2000 technology, its architecture is ideal for compute-intensive tasks such as data processing, high-performance data analytics, artificial intelligence and machine learning.
