It achieves 17.59 Petaflop/s with 560,640 cores, beating the previous number one, the Sequoia at Lawrence Livermore National Laboratory, which reaches 16.32 Petaflop/s.

Sequoia is the name of the the fastest supercomputer in the world, as ranked by Top500. IBM built the BlueGene system and it’s  installed at the US Department of Energy’s Lawrence Livermore National Laboratory.

Sequoia is capable of over 16 PFLOPS (quadrillion operations per second) compared to the 10.5 PFLOPS of the previous number one, which was the K Computer at the RIKEN Advanced Institute for Computational Science in Kobe, Japan.

With a new number one, we wanted to see how things have developed over the last couple of decades. We grabbed the specifications for the number one supercomputer from the Top500 website, going back to June 1993, and here’s what we found.

We were curious about this ourselves. We’ve all seen the almost absurd numbers involved with the very top sites (like Facebook), but what about website number 50, or 100, or 500? What does it take for a website, in terms of visitors, to reach such a ranking?
