Scientists battle to build biggest supercomputer · Sun's £30m device soon to be overtaken by rival IBM · Machines getting more powerful and less costly Bobbie Johnson, technology correspondent Wednesday June 27, 2007 The Guardian Scientists yesterday unveiled a new generation of supercomputers, including a £30m machine with the memory of 200,000 home computers and a hard disk hefty enough to hold the entire Google index of the internet. The huge devices, each costing tens of millions of pounds, will compete against each other this year for the title of the planet's biggest electronic brains. The first contender, Constellation, has been built by Sun Microsystems at a cost of $59m (£30m) and boasts a 1.7 petabytes hard disk. It was unveiled yesterday at the International Supercomputer conference in Dresden, Germany. The machine - which will go live later this year - can operate at speeds of 421 teraflops, or 421 trillion calculations a second. This will outstrip IBM's 280 Teraflop Blue Gene/L, currently ranked as the world's fastest computer, by some distance. But operating at such levels will be a significant power drain, requiring the same amount of power to run as a high-speed intercity train. ... technology.guardian.co.uk
