SPEED IS THE KEY TO WORLD'S SUPERMACHINES

SUPERCOMPUTERS play a vital role in the defence industry as they can be used to test nuclear weapons, design missiles and develop technology that can crack complex computer codes used to protect sensitive information. A supercomputer's power is measured by the number of theoretical operations it can perform per second.


US Commerce Department export rules apply to computers with minimum speeds of between 2,000 and 7,000 million theoretical operations per second that are shipped to so-called Tier 3 countries, including the mainland, Russia, Israel and India.


US lawmakers enacted the rules after reports that supercomputers had ended up in defence-related operations on the mainland and Russia.
