At the international ISC High Performance 2024 conference held on 12-16 May in Hamburg, new TOP500 and Green500 lists of the most powerful supercomputers in the world have been announced. The fastest computational machine in Poland is now Helios from the AGH University Academic Computer Centre CYFRONET. For the first time in the history of Polish computer science, as many as 4 supercomputers from a single centre, CYFRONET, are included on the prestigious TOP500 list. Moreover, Helios ranks 3rd on the Green500, namely the list of the most energy-efficient supercomputers. Thus far, none of the Polish systems have reached so high.
