UK Meteorological Office has entered into a contract with Cray to build world’s most powerful computing system designed exclusively for the analysis of climate change and weather forecasting.
At the heart of the complex – Cray XC40 hardware platform based on Intel server processors Xeon and storage system Cray Sonexion. Building a supercomputer will be implemented in three phases, and the total cost of the project will reach $ 128 million. It will be the largest for Cray contract outside the United States.
After entering the supercomputer commissioned its performance will be approximately 16 petaflops ( quadrillion floating point operations per second). For comparison, now the most powerful computing system of the world – the Chinese Tianhe-2 complex – has the speed to 33.86 petaflops (peak performance of 54.9 petaflops).
The new British supercomputer total weight of about 140 tons located in Exeter (Devon). Its storage subsystem can hold up to 20 petabytes of information, providing a capacity of 1.5 TB / s.
It is noted that the rapid development of computer technology today allows you to make a four-day weather forecasts with the same accuracy as the day 30 years ago. The advent of the new supercomputer will bring periods of forecasting to five or six days without loss in accuracy.
