A thousand people from all over Europe, including Sergio Mattarella, President of the Republic, came to Bologna for the opening of the "Leonardo" supercomputer, which is the fourth fastest and most powerful computer in the world. It was commissioned by the European Commission and the Ministry of University and Research. "Leonardo" in Bologna will be operated by Cineca, a partnership of 69 Italian universities, two ministries, and 27 national public institutions, and has a measured High-Performance Linpack (HPL) performance of 174.7 petaflops (millions of billions of floating point operations per second). For these reasons, it has risen to the fourth spot on the Top500 list of the world's most powerful supercomputers, as revealed at Sc22, the premier international conference for High Performance Computing now taking place in Dallas, Texas. The Emilian supercomputer, which now consists of 155 "cabinets" packed of processors (racks), 5,000 nodes, and a weight of 340 tons, will undergo additional upgrades in the coming weeks; Cineca and Atos want to increase its speed up to 240 petaflops.
