SUMMARY:Porting NEMO to GPUs with PSyclone
DESCRIPTION:Minisymposium\n\nSergi Siso (Science and Technology Facilities
  Council)\n\nPSyclone is a source-to-source code-generation and transforma
 tion system designed to enable performance portability and code maintainab
 ility for weather and climate codes written in Fortran. To achieve this, i
 t separates the scientific code, written in Fortran, from the optimisation
  and parallelisation steps, encoded as python scripts. HPC experts can the
 n prepare the PSyclone recipes that are needed to take advantage of each h
 ardware platform without altering the domain science code. PSyclone is bei
 ng used to optimise unaltered directly-addressed MPI applications, such as
  NEMO, and offload their computations to GPUs. In this talk I will demonst
 rate the use and performance of PSyclone for a production configuration of
  NEMO used by the UK MetOffice and I will provide an update about the inte
 gration of PSyclone into the NEMO build system and its use by the NEMO com
 munity.\n\nDomain: Climate, Weather, and Earth Sciences, Computational Met
 hods and Applied Mathematics\n\nSession Chairs: Iva Kavcic (Met Office), C
 hristopher Michael Maynard (Met Office), and Wei Zhang (Oak Ridge National
  Laboratory)
