The project aims to understand the performance of the NorESM code. We will:

  • Review the MPI pe mapping of the different sub-models (atmosphere, land, sea ice and ocean) currently used for model simulations.
  • Analyze the NorESM code to identify code sections and routines to be further evaluated for performance optimization. We will do this by running suitable test cases through analysis tools such as Scalasca and VTune.
  • Propose a set of recommendations for code optimization changes based on the performance analysis.
