In graphics: Supercomputing superpowers

The biannual Top 500 supercomputer list has alternative supercomputer powers.

The data used to generate the interactive treemap visualisation come from a draft of the June 2010 TOP500 Supercomputing list., external 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.
