Exascale computing

Exascale computing refers to computing systems capable of calculating at least "10¹⁸ IEEE 754 Double Precision (64-bit) operations (multiplications and/or additions) per second (exa FLOPS)";^[1] it is a measure of supercomputer performance.

Exascale computing is a significant achievement in computer engineering: primarily, it allows improved scientific applications and better prediction accuracy in domains such as weather forecasting, climate modeling and personalised medicine.^[2] Exascale also reaches the estimated processing power of the human brain at the neural level, a target of the now defunct Human Brain Project.^[3] There has been a race to be the first country to build an exascale computer, typically ranked in the TOP500 list.^[4]^[5]^[6]^[7]

In 2022, the world's first public exascale computer, Frontier, was announced.^[8] As of June 2024^[update], it is the world's fastest supercomputer.^[9]
