Superfast computers2024 is set to be a “bumper year” for speedy computers. Europe will turn on its first exascale supercomputer called Jupiter, which can perform one quintillion computations per second. It will be used to create digital twins of the human heart and brain, as well as run high resolution simulations of the Earth’s climate. In case you were wondering, America already has an exascale supercomputer called Frontier, but this year it will install two more called Aurora and El Capitan to create maps of the brain and neural circuits, and to simulate the effects of nuclear weapon explosions.
