Cray Deploys 40,000-core ATERUI II Supercomputer at CfCA in Japan

The Center for Computational Astrophysics has deployed a new Cray XC50 supercomputer. With a peak performance of 3 Petaflops, the ATERUI Ⅱ system is the world’s fastest supercomputer for astrophysical simulations. Powered by over 40,000 cores (Intel Xeon Scalable processors) the system features 386 Terabytes of memory. “Thanks to the rapid advancement of computational technology in recent decades, astronomical simulations to recreate celestial objects, phenomena, or even the whole Universe within the computer, have risen up as the third pillar in astronomy.”
