For the first time, every entry in this year's TOP500 list delivers petaflop-level capabilities, with the lowest ranking system coming in at 1.022 petaflops.
The top two supercomputers in the world, known as Summit (housed at Oak Ridge National Laboratory) and Sierra (housed at Lawrence Livermore National Laboratory), have reached performance levels of 148.6 petaflops and 94.6 petaflops, respectively.
In terms of hardware, Summit is powered by 4,356 nodes, all of which contain two Power9 CPUs with 22 cores each and six NVIDIA Tesla V100 GPUs. Sierra is made up of 4,320 nodes with two Power9 CPUs and four NVIDIA Tesla V100 GPUs inbuilt in each node.
The third and fourth places on the latest TOP500 list go to China's Sunway TaihuLight system (93.0 petaflops) and Tianhe-2A (61.4 petaflops).
Of the 500 most powerful computers in the world, China is home to 219, while the U.S. has just 116.
