Oak Ridge National Laboratory (ORNL) in the US has constructed the world's first exascale computer.
A normal laptop only has a few teraflops, or a trillion processes per second.
Frontier, an exaflop computer, might aid with climate modelling, nuclear fusion simulation, and medicine development.
ORNL's Thomas Zacharia said Frontier will provide high-performance modelling and simulation.
The Frontier computing system has 9400 CPUs (ordinary computer processors) and 37,000 GPUs (processors intended to produce 3D graphics) in 74 distinct cabinets.
A normal laptop has 5 to 9 cores. At peak power, the computer creates so much heat that four high-powered pumps must circulate 25,000 litres of water each minute.
