The Japanese Fugaku supercomputer, installed at the RIKEN Center for Computational Science, extended its lead at the top of the latest TOP500 list.
According to the announcement, this list reflects a flattening of the performance growth curve as well as the least number of new entries recorded since the project began in 1993.
In the six months since the previous list came out, Fugaku increased its performance on the new mixed precision HPC-AI benchmark from 1.4 exaflops to 2.0 exaflops. Fugaku also achieved a record HPL performance of 442 petaflops, having increased its Arm A64FX capacity from 7,299,072 cores to 7,630,848 cores. This performance puts it three times ahead of Oak Ridge National Laboratory’s Summit occupying second place on the list.
Lawrence Livermore National Laboratory’s Sierra system, Sunway TaihuLight installed at the National Supercomputing Center in Wuxi, China, and NVIDIA’s Selene system round out the top five.
