Japan Captures Top500 Crown
FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.—The 55th edition of the TOP500 saw some significant additions to the list, spearheaded by a new number one system from Japan. The latest rankings also reflect a steady growth in aggregate performance and power efficiency.
The new top system, Fugaku, turned in a High Performance Linpack (HPL) result of 415.5 petaflops, besting the now second-place Summit system by a factor of 2.8x. Fugaku, is powered by Fujitsu’s 48-core A64FX SoC, becoming the first number one system on the list to be powered by ARM processors. In single or further reduced precision, which are often used in machine learning and AI applications, Fugaku’s peak performance is over 1,000 petaflops (1 exaflops). The new system is installed at RIKEN Center for Computational Science (R-CCS) in Kobe, Japan.
Number two on the list is Summit, an IBM-built supercomputer that delivers 148.8 petaflops on HPL. The system has 4,356 nodes, each equipped with two 22-core Power9 CPUs, and six NVIDIA Tesla V100 GPUs. The nodes are connected with a Mellanox dual-rail EDR InfiniBand network. Summit is running at Oak Ridge National Laboratory (ORNL) in Tennessee and remains the fastest supercomputer in the US.
