Summary

  • compute per-dimension grid partitions so each MPI rank owns its proper local extents even when grid sizes change
  • replicate the full source grid on all ranks and parallelize interpolation work with MPI collectives
  • expand SpatialGrid to track independent x/y extents for consistent boundary checks

Testing

  • mpic++ main.cpp -o main -larmadillo (fails: mpic++ not available in container)
