Will Taihu Light and Tianhe 2A continued to be third and fourth respectively, while China led the U.S. by 227 units. One other bright spot when you look at the processor alone is that AMD EPYC processor is on the list for the first time, and this is the first time in many years that AMD platform has returned to the top tier.
There are four finalists, the best ranking is “JOLIOT-CURIE ROME” ranked 59th, a set of Atos Bull Sequana XH2000, using a custom Rome second generation EPYC 7H12, 64 core 128 threads, Main frequency 2.6GHz, a total of 2500, 160,000 cores, maximum floating-point performance of 3.686PFlops (3.686 trillion floating-point calculations per second), power consumption of 795kW.
Another second-generation EPYC Supercomputing “Spartan” ranked 433rd, also using the Atos Bull Sequana XH2000 system and the Dragon 7H12 processor, but only 676, 43264 cores, maximum performance of 1.266PFlops, power consumption 219kW.
