Thought for the month

“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”

Margaret Thatcher, 1 October 1996.

Sequoia stands tall

The bi-annual TOP500 list of the world's fastest supercomputers shows that IBM has regained top spot. The supercomputers were ranked according to The Linpack Benchmark test which gives each computer a petaflop/s score (quadrillion floating-point operations per second). Sequoia, the IBM BlueGene/Q system at the Department of Energy’s Lawrence Livermore National Laboratory tested at 16.32 petaflop/s compared to second place, Fujitsu's K Computer with 10.51 petaflop/s. The 96 rack Sequoia is used to carry out simulations to help extend the life of aging nuclear weapons. The first list in 1993 was headed by the CM-5/1024 designed by Thinking Machines; the 2012 IBM machine is 273,930 times faster. The IBM 'Blue Joule' at the STFC Daresbury Laboratory is the UK's top supercomputer listed as number 13 in the world.
