The TOP500 list has ranked the world's fastest computers twice a year since 1993, which is the year this page is pretending to be from. Every machine is measured on the same task - solving a very large system of linear equations - and ranked on the arithmetic it sustains while doing it. It is the oldest continuously published frontier in computing and the only one on this site that arrives on a schedule, every June and every November. It is here partly because it is the ground everything else on this page runs on, and partly because a homepage like this one, in 1993, would have found the first list astonishing: the fastest machine in the world that year would today be beaten by a good workstation.

That description was written when this frontier was opened, on 2026-09-07, and is never rewritten. Where it and the number above it disagree, the number is the reading and the description is history.


What counts
The Rmax figure of the number one system on the current TOP500 list - sustained performance on the list's own benchmark, not theoretical peak.
What moves it
A new TOP500 list is published, every June and November.
