ICL Research Profile



With over three decades of tracking the progress of high performance computing, the TOP500 list continues to provide a reliable historical record of supercomputers around the world. The list clearly lays out critical HPC metrics across all of its 500 machines and draws a rich picture of the state of the art in terms of performance, energy consumption, and power efficiency. The TOP500 now features an HPCG ranking, which measures a machine’s performance using irregular accesses to memory and fine-grain recursive computations- the very factors that dominate real-world, large-scale scientific workloads.

In November 2021, the 58th TOP500 list was unveiled during the International Conference for High Performance Computing, Network, Storage, and Analysis (SC21), which was held in Saint Louis, Missouri, and online. Yet again, Japan took the crown with Fugaku, their new ARM-based machine built by Fujitsu. The system’s 158,976 A64FX SoCs propelled Fugaku to 442 Pflop/s in the HPL benchmark, making it the fastest supercomputer in the world by a factor of 2.8x over the United States’ Summit machine and the first ARM system to achieve the number one spot on the TOP500. Fugaku now held the first spot for 4 consecutive lists.
