HPC5 is a set of parallel computing units capable of delivering a peak processing power of 51.7 Petaflops/s. Coupled with the supercomputing system already operational since 2018 (HPC4), the combined computing infrastructure reaches a peak power of 70 Petaflops/s, i.e. 70 million billion mathematical operations performed in one second. Its full name is High Performance Computing - layer 5 and it is Eni’s latest-generation supercomputer. 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 where HPC5 is used is geophysical exploration, the study of the subsurface to identify new hydrocarbon deposits. The supercomputer also supports the development of renewable energy and research into new forms of energy, such as energy from sea waves and magnetically confined fusion. HPC5 was inaugurated on 6 February 2020 and is currently the most powerful non-governmental supercomputer in the world, ranking 15th in the TOP500 world ranking (June 2023). The Green Data Centre in Ferrera Erbognone was built in 2013 and houses HPC4 and HPC5. It is one of the most energy-efficient and lowest carbon intensive computing centres in Europe, with a PUE index of 1.234 (2022). The PUE (Power Usage Effectiveness) index indicates the efficiency of a computing centre, i.e. the ratio of the total energy consumed by the facility to that used for computing operations alone.
