The Cray XC40TM is a new supercomputer, costing $156 million, that could help make the UK a world leader in weather forecasting and climate science. The supercomputer will be used by the Met Office, the UK's public climate research and weather agency.

This supercomputer is one of the fastest in the world -- it comprises 480,000 cores, 2 million GB of memory and can store up to 17 million GB of data. In peak performing conditions, it is capable of making 16,000 trillion calculations per second. This represents a significant upgrade over the IBM Power 775, which has a memory of 80,000 GB, can store up to 2 million GB and can make 1,200 trillion calculations a second.

The computer will allow for highly detailed and precise weather forecasting and high-resolution weather modeling. It will effectively be able to predict differences in weather conditions between individual streets. These and other capabilities could help the computer contribute billions of dollars in socio-economic benefits to the UK.
