Supercomputer For Astronomy “ATERUI” Upgraded To Double Its Speed


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.

Data obtained by observations are snapshots of astronomical phenomena. To understand these data, we need to construct theories based on physics, and conduct experiments based on those theories. However, virtually no astronomical phenomena can be reconstructed in a laboratory due to the spatial and time scales involved. On the other hand, theoretical astronomy tries to understand astronomical phenomena by solving equations. In some cases, it is not easy to solve the equations by hand, so powerful computers assist astronomers.
