The Joliot-Curie supercomputer was inaugurated in June 2019 as part of the international race to develop exascale computing – processing power of one billion billion calculations per second. The competition is dominated by China and the United States, which currently lead with a 200-petaflop supercomputer and have their first exaflop computer on the drawing board. Joliot-Curie will reach 22-petaflop capacity – 22 million billion operations per second – by 2020. It will be Europe’s third most powerful research computer and hold the number one spot in France. With Joliot-Curie, France is living up to its commitment to make computer power available to European researchers as part of the PRACE European computing infrastructure.
