Financial Times - Supercomputers: Battle of the speed machines < 5min

With its flying buttresses and domed roof, the Terascale Simulation Facility at the Lawrence Livermore National Laboratory was built as a cathedral to the supercomputer. … The design may suggest some religious reverence for the all-powerful machines. More practically, though, it means they are unencumbered by supporting columns, saving space and creating a more direct route for the arteries of cables to feed and cool the world’s fastest supercomputers. But less than 10 years after being built, the building is already in danger of becoming outdated. … “When we designed this building, we thought it would be good for 50 years but already it’s only adequate and not robust,” says Mike McCoy, who leads the supercomputing effort at Lawrence Livermore as director of the Advanced Simulation and Computing programme. … Even its name risks becoming an anachronism. Terascale computing has been superseded by petascale computing – 1,000 times faster. By 2020, we will be in the exascale age – a thousand times faster again.
