TOP500 Supercomputer Rankings

Every six months TOP500 publishes a list of the five hundred most powerful computer systems n the world. This is probably a good guide to the economic, scientific and technological future of the world's nation states.

The most noticeable change since November 2015 is that the number of supercomputers in China has risen dramatically from 108 to 171 systems while the USA has fallen from 200 to 171. Japan has fallen quite considerably from 37 to 27 and Germany and the UK by one each. France has added two supercomputers to reach 20.

In the whole of Africa there is exactly one supercomputer, in Cape Town. In the Middle East there are five, all in Saudi Arabia, three of them operated by Aramco.
