Summary

Find out the history and background to National Exascale Day

Began in 2019, National Exascale Day celebrates the scientists and researchers who make breakthrough discoveries in medicine, materials sciences, energy and beyond with the help of some of the fastest supercomputers in the world.

Exascale computing is a computing system that can perform a least one exaflops, or one quintillion (a billion billion) calculations per second. For reference, the Milky Way Galaxy is one quintillion kilometre wide. October 18 was labeled National Exascale Day because a quintillion is 10¹⁸.

Join the Exascale Day celebrations by using #ExascaleDay on social media channels and participating in social media quizzes that highlight scientific discovery and the scientists and research behind it, and illustrate how exascale computing will impact the world.
