Supercomputer astronomy: The next generation

(National Institutes of Natural Sciences) The supercomputer Cray XC50, nicknamed NS-05 'ATERUI II' started operation on June 1, 2018. With a theoretical peak performance of 3.087 petaflops, ATERUI II is the world's fastest supercomputer for astrophysical simulations. ATERUI simulates a wide range of astronomical phenomena inaccessible to observational astronomy, allowing us to boldly go where no one has gone before, from the birth of the Universe itself to the interior of a dying star.
