MPAS: Model for prediction Across Scales(Work in Progress)

  • Recall that MPAS meshes must be partitioned using Metis in order for MPAS to be run in parallel.

  • However, the meshes available from the MPAS-Atmosphere download page are provided with several pre-computed partition files.

  • mpas/meshes/ 디렉토리에 x4.535554.graph.info.part.1024와 같이 parted 된 그래프 파일이 있음.

  x1.40962.grid.nc – the mesh itself
  x1.40962.graph.info – the mesh connectivity graph
  x1.40962.graph.info.part.2 – pre-computed partitioning for 2 MPI tasks
  x1.40962.graph.info.part.8 – pre-computed partitioning for 8 MPI tasks
  x1.40962.graph.info.part.16 – pre-computed partitioning for 16 MPI tasks
