Inside The MET Office Weather Supercomputer

The MET Office's main tool to forecast weather in the UK has been branded, perhaps unjustly, as one of the worst polluters in the public sector in the United Kingdom.

The computer, an IBM P-Series model, was purchased by the Meterological organisation for the rather impressive sum of £33 million back in May last year. In comparison, the MET Office new headquarters cost £80 million.

In terms of hardware, it uses the same processors as a Playstation 3, the Cell Broadband Engine, together with 13TB worth of memory and an array of hard disk drives totalling 550TB. All of this to run the MET's intricate simulations more precisely using the organisation's proprietary Unified Model code.

It consumes a staggering 1.2 Megawatts of energy and and that amount of power could power a small town. It also leaves a huge carbon footprint given the fact that it runs 24 hours a day - it takes eight weeks to boot up - and accounts for 75 percent of the Met Office's building.

Incredibly, the 5-year contract signed by the MET means that the computer system will only be ready by 2011 when it will be 30 times more powerful than the organisation's current computer but will only be the second most powerful in the country.

When it is completed, the computer is expected to top one one quadrillion floating point operations per second or one Petaflop, churning enough data for 400 scientists.

Our Comments

IBM's Roadrunner, the world's fastest supercomputer currently 1.1 Petaflop, is in operation at the Department of Energy, Los Alamos National Laboratory, New Mexico, USA. In 2011, IBM will launch Sequoia which has a targeted performance of 20 Petaflops.
