The throne of the world's fastest supercomputer is now held by Frontier whose development was announced in 2019. It is also the world's first supercomputer to exceed the performance limit of 1 ExaFlop with the ability to reach 1,102 Exaflop/s in tests conducted so far. This is according to the latest Top500 chart announced yesterday.
This is still below the original target of 1.5 ExaFlops when it was designed and there are still many performance improvements to be made in the future. Frontier is located at Oak Ridge National Laboratory (ORNL) in the United States with it using the HPE Cray EX235a architecture and equipped with an AMD EPYC 64C 2GHz chip. The entire system has 8,730,112 cores in all with a power efficiency of 52.23 gigaflops/watt.
Frontier replaces Fugaku located at the RIKEN Center for Computational Science (R-CCS), Kobe, Japan which held the throne as the world’s fastest supercomputer for two years. Fugaku only has the ability to process 442 PFlop/s which is still three times more powerful than the third most powerful LUMI supercomputer located in Finland.
