Japan’s Fugaku System Tops Latest Supercomputer List

The latest TOP500 list of supercomputers reflects significant shifts since the previous list was released last November. At number one is the Fugaku system from Japan, which posted a High Performance Linpack (HPL) result of 415.5 petaflops. Fugaku is powered by Fujitsu’s 48-core A64FX SoC, making it the first ARM-based system to reach the highest ranking. 

According to the technical report written by Jack Dongarra, the Fugaku system achieved a stunning 1.42 Exaflops/s on the HPL-AI benchmark, which highlights “the emerging convergence of high-performance computing (HPC) and artificial intelligence (AI) workloads.” In comparison, the Summit system, which previously occupied the top spot, achieved .55 Exaflop/s on the benchmark. 

With this list, the Summit system at Oak Ridge National Laboratory in Tennessee moves into second place overall – delivering 148.8 petaflops on the Linpack benchmark – but remains the fastest supercomputer in the United States.

Rounding out the top five are the Sierra system at Lawrence Livermore National Laboratory in California, China’s Sunway TaihuLight, and the Tianhe-2A (Milky Way-2A).
