SUMMARY:A Whirlwind Tour of the PSyclone DSL
DESCRIPTION:Minisymposium\n\nA Whirlwind Tour of the PSyclone DSL\n\nFord\
 n\nPSyclone is a configurable domain-specific compiler which supports both
  code generation and transformation, and is primarily designed for finite 
 difference/volume/element weather and climate models written in Fortran. P
 Syclone is used by the U.K. Met Office in LFRic, their next generation atm
 osphere model and is being developed for use in the NEMO ocean model. PSyc
 lone supports a separation of concerns between the science code and its pa
 rallelisation and optimisation on the underlying target<br />architecture,
  with PSyclone being responsible for the latter. This separation helps cod
 e development, as it allows scientists to<br />concentrate on implementing
  the science, and helps performance portability as PSyclone can tailor the
  parallelisation and<br />optimisation to the particular software and hard
 ware. Some key features of PSyclone are 1) its evolutionary approach to<br
  />performance portability - existing Fortran codes do not have to be comp
 letely rewritten, 2) its use of optimisation scripts which are<br />design
 ed to support the HPC expert and 3) its use of a language independent inte
 rnal representation, allowing code to be output in<br />different represen
 tations, enabling parallelisation using approaches not supported in Fortra
 n, such as OpenCL as well as the potential of interoperability between PSy
 clone and other DSLs. This presentation will introduce PSyclone, its use i
 n LFRic and NEMO,<br />its current status and future developments.\n\nDoma
