SUMMARY:CSM07 - Building a Performance Portable Software System for the Me
 t Office's Weather and Climate Model, LFRic
DESCRIPTION:Poster\n\n\nCSM07 - Building a Performance Portable Software S
 ystem for the Met Office's Weather and Climate Model, LFRic\n\nMaynard\n\n
 LFRic is the weather and climate model being developed by the Met Office t
 o replace the Unified model for exascale computing architectures. A domain
  specific language has been developed to enable single science source code
  which can then be run on different architectures. It exploits a domain sp
 ecific compiler and code generator called PSyclone to generate the differe
 nt parallel code for different architectures. The general concepts of the 
 DSL are illustrated and scaling results for MPI, MPI and OpenMP on the Met
  Office XC40 machine are shown. Preliminary experiments with OpenACC code 
 for GPUs are also shown for key computational kernels. Finally the de
 velopment path for harnessing FPGA acceleration is described, showing the 
 outcome of preliminary experiments on the architecture of the EuroExa proj
 ect. The software system allows for single source science code development
  whilst at the same time allow for different architecture targets and opti
 misations.
