HPC5 is a set of parallel computing units with a peak processing power of 51.7 petaFlops. Combined with the supercomputing system in operation since 2018 (HPC4), the peak computational capacity of the infrastructure totals 70 petaFlops: that is, 70 million billion mathematical operations performed in a single second. Its full name is High Performance Computing - layer 5 and it is the latest generation of Eni’s supercomputers. It implements very advanced data processing algorithms and applies them throughout the energy value chain. This software is also developed internally by Eni. An important area of HPC5 use is geophysics exploration: the study of the subsurface to identify new hydrocarbon deposits. But the supercomputer also supports research into new forms of energy, such as wave motion and magnetic confinement fusion. Inaugurated on 6 February 2020, in June 2020 it entered the TOP500 ranking as the sixth most powerful supercomputer in the world and the first in Europe. In November 2022, it proves to be the most powerful industrial supercomputer in the world. In June 2020, HPC5 also entered the GREEN500 special list, achieving the same position as the sixth most energy-efficient supercomputer in the world, ranking first in Europe and again first overall among all industrial computing system. Up until now, HPC5 is one of the most powerful non-governmental supercomputers in the world, while the Green Data Centre in Ferrera Erbognone, which was built in 2014, is one of the most energy-efficient computing centres in the world. If we disregard experimental computers by considering only supercomputing systems with more than 500,000 computing cores, HPC5 ranked as the world's second most energy-efficient computer in 2020 and still occupies fifth place in June 2022. A single watt of electricity enables it to perform almost twenty billion operations per second. The performance level of this computer means it can use extremely sophisticated in-house algorithms to process subsoil data.
