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 (exaFLOPS)";[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 November 2024[update], Lawrence Livermore National Laboratory's El Capitan is the world's fastest exascale supercomputer.[9]
