- Additional information
- The Met office is developing a new weather and climate model to exploit Exascale computers provided by its £1bn procurement exercise. This paper implements an algorithm with reduced parallel communication, thus enhancing the parallel scalability of the model. Mathematics and computer science contribute to representing the algorithm and extending the Domain specific language (DSL) used. The parallel code can then be generated automatically. Consequently, the Met office will be able to efficiently use its supercomputers to increase the accuracy of its weather forecasts and climate predictions.
