New fastest computer in the world – and it is so quick that it requires a new word to describe it, says an article published on Independent.
Next seven supercomputers
The Frontier system at the US Department of Energy’s Oak Ridge National Laboratory is now the fastest computer on the Top500 list, which ranks the most powerful in the world.
The supercomputer is not only the fastest in the world, but easily so. It is so powerful that it is faster than all of the next seven supercomputers in that ranking, combined.
Liquid cooling
As well as top ranking on the Top500 list, Frontier also took the top spot on the Green500 list, which ranks supercomputing systems according to how efficient they are.
Its energy efficiency is achieved in part through its liquid cooling – which requires pumping 6,000 gallons of water through the system each minute.
First to break
It also brings the crown back to the US, from Japan. The record has been held for two years by the Fugaku system at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan, but that has now been dropped to number two.
The Frontier computer is not only the most powerful one in existence, but the first to break through the “exaflop ceiling”, and become the first “exascale” machine. Exaflop or exascale computing refers to those that are able to do 1018 operations in one second.
Geopolitical tensions
In theory, the previous record holder Fugaku was able to work at more than 1 exaflop, too. But it was unable to demonstrate that in practical tests – and Frontier has a theoretical maximum of more than 2 exaflops.
China is also thought to have potentially developed two exaflop systems of its own, but has not submitted them to the Top500 committee for official recognition because of geopolitical tensions.
Extra challenges
Researchers will be able to start using the supercomputer fully from later this year.
Frontier is made up of 74 cabinets, each of which weighs 8,000 pounds. The Oak Ridge National Laboratory noted that it had been able to put it together during the pandemic, which added extra challenges to the already significant difficulties of installing those cabinets, which together require 90 miles of networking cables to link together, for instance.
