LFRic

"LFRic is the name given to the programme of work that is intended to deliver a replacement for the Unified Model towards the end of this decade. The name LFRic is chosen in recognition of Lewis Fry Richardson whose fantasy of parallel computation of weather is nearing its centenary. LFric is pronunced elfrick.

Currently LFRic is a Met Office-led project working closely with the ​GungHo project. In turn, the GungHo project is a collaboration between the Met Office, NERC and STFC to develop a new and scalable dynamical core to replace ENDGame, which is the dynamical core used in the current Met Office Unified Model (UM). GungHo is a project within the JWCRP framework.

The key challenges of GungHo and LFRic are to deliver models that produce good weather forecasts and climate simulations, and that run effectively on future generations of supercomputers. At the moment we cannot be sure what these computers will be like, but it is likely that they will comprise many hundreds of thousands of individual compute cores, each with a relatively small amount of local memory.

The designs of GungHo and LFRic will therefore focus on enabling calculations to be broken down into chunks that are sufficiently small to fit into the local memory of a processor, but large enough to enable to processor to effectively vectorise the calculations. The challenge is both a scientific and technical challenge."
