The biannual Top 500 supercomputer list has been released. Use this graphic to explore the world's fastest number crunchers or find out more about alternative supercomputer powers.

About this data:

TREEMAPS A treemap is a way of analysing large amounts of data in a small space

In this example the top 500 supercomputers have been depicted in proportion to their speed as of 31 May A history of treemaps

The data used to generate the interactive treemap visualisation come from a draft of the June 2010 TOP500 Supercomputing list. This ranks most of the world's fastest supercomputers twice a year. There may be minor differences between this list and the final published list.

The graphic allows you to visualise the list by the speed of each machine; the operating systems used; what it is used for; the country where it is based; the maker of the silicon chips used to build the machine and the manufacturer of the super computer.

The maps were produced using the Prefuse Flare software, developed by the University of California Berkeley.
