HPC4 is the most powerful energy sector industrial supercomputer in the world. "Our data center is located in the green area of Lomellina - explains Gabriele Provara, head of IT operations of the Eni group -. It was born green because we designed it to move large, enormous quantities of airflow at very low speeds. The airflow goes back up and is filtered. It is then used to cool our electronic equipment, our telecommunication systems and our processing systems, after which we put the filtered air back into the environment. In 2015 we set a new world record for energy efficiency”.
