ARM-Based Supercomputer Earns Top Spot in Global Ranking

The world’s fastest supercomputers are ranked twice a year, and Innovative Computing Laboratory director Jack Dongarra, one academic behind the rankings, noted that the Top500 list of the world’s fastest high-performance computing (HPC) systems is showing “flattening performance” due to the slowdown of Moore’s Law. In the most recent ranking, Japan’s Fugaku ARM-based supercomputer set a record of 442 petaflops. In 2021, however, the first exascale — 1,000 petaflops — supercomputers are expected to appear, including one from the Oak Ridge National Laboratory in Tennessee.

ARM-Based Japanese Supercomputer Now No. 1 on Top500

While the United States and China compete to create the world’s most powerful computers, a Japanese supercomputer, dubbed Fugaku, took first place in Top500’s speed ranking. At the Kobe-based RIKEN Center for Computational Science, Fugaku achieved 2.8 times more calculations per second than the previous speediest system, IBM’s at Oak Ridge National Laboratory in Tennessee. Fugaku, which pushed another IBM computer at Lawrence Livermore National Laboratory in California to third place, is based on ARM chip technology.
