LFRic Core vn3.0 Release Notes

Full Changelog: core2.2...vn3.0

This is the first GitHub release of LFRic Core. Please see the refreshed Working Practices for details on how to migrate branches and work with GitHub.

Key Changes

  • Additional infrastructure has been added to support flexible checkpointing in LFRic Apps. This includes, a key_value_collection_iterator class, string splitting functionality, and some refactoring of the lfric_xios component to allow multiple checkpoint files to be written (ticket:4020).
  • Mesh generators now have OpenMP support for generating partitioned meshes, enabling generation of meshes in a reasonable time when running at scale (for example, running a 10km global model on several thousand ranks can now be done in a few minutes on 32 cores).
  • Sphinx based documentation hosted on GitHub

Linked Codebases

This release is part of the 2025.12.1 Simulation Systems Release.
