The Center for Computational Astrophysics (CfCA) of the National Astronomical Observatory of Japan upgraded the supercomputer Cray XC30 system “ATERUI”. By introducing state-of-the-art CPUs, the theoretical peak performance increased from 502 Tflops to 1.058 Pflops, which means that ATERUI made the leap to become a petaflops computer. The new ATERUI will expand the horizons for simulations to understand the Universe and astrophysical phenomena.
