Компания IBM построила суперкомпьюетр Roadrunner, чья производительность составила 1,026 петафлоп. Новая система сместила с первого места в рейтинге самых мощных компьютерных систем другой суперкомпьюетр IBM, модель BlueGene/L, мощность которого составляет 0,478 петафлоп.
В основе IBM Roadrunner лежит 12960 процессоров Cell, работающих в блейд-серверах QS22, и 6948 двухъядерных AMD Opteron, работающих в блейд-серверах IBM LS21. Объем оперативной памяти суперкомпьютера равен 80 терабайт.
