MAPL 2.69.0

Note to developers

This will be the last version of MAPL v2 based on the develop branch. MAPL v3 is now in active development and the develop branch will soon be MAPL v3 based.

We will branch main off of v2.69.0 as release/v2 and all PRs for MAPL v2 should be based on the release/v2 branch.

---

This release includes bug fixes, an enhancement to ExtDataDriver.x, and the removal of the short-lived MAPL_SUPPORT_MAPL3 build option.

Key Highlights:

• New RUN_LIKE_MODEL option in ExtDataDriver.x: Controls whether the clock ticks before (model-like) or after (default/legacy) each step, making it easier to reproduce true model behavior in testing (#4886).

• ExtData2G non-CF vertical coordinate compatibility: Improved handling of non-CF dimensionless vertical coordinates; standard_name is now mapped to long_name for better compatibility with non-CF inputs (#4802).

• Bug Fixes:

  • Fixed a bug in WireComponent affecting TerminateImport and removed an unnecessary _ASSERT in MAPL_TerminateImportAllBut (#4674).
  • Fixed an informative error message when extrapolation is attempted without a valid range in ExtData2G (#4649).
  • Fixed SIGFPE (integer divide by zero) in MAPL_LoadBalanceMod when the load balancing algorithm evaluates maximum differences to zero (#4643).
  • Python bridge: removed an odd 3rd-party dependency caused by importing no_type_check outside the standard library (#4800).
  • Relaxed the comparison standard for grid_is_ok (#4870).

All testing shows this is zero-diff to MAPL 2.68.0

---

This version of MAPL was tested with:

• Intel Fortran Classic (ifort) 2021.13
• Intel Fortran (ifx) 2025.3
• GCC 13.2.0, 14.2.0, and 15.2.0
• NAG 7.2
• Flang 22.1

The libraries this version of MAPL is currently tested with are below.

• Baselibs 8.27.0
  • netcdf-c 4.9.2
  • netcdf-fortran 4.6.1
  • ESMF 9.0.0b10 (Note: MAPL only requires 8.6.1 at the moment)
  • GFE 1.23.0
    • gFTL 1.17.0
    • gFTL-shared 1.12.0
    • pFUnit 4.16.0 (optional)
    • fArgParse 1.10.0 (if -DBUILD_WITH_FARGPARSE=YES, default=YES)
    • pFlogger 1.18.0 (if -DBUILD_WITH_PFLOGGER=YES, default=YES)
  • UDUNITS2 2.28.8

Also, if you build with Baselibs and/or -DUSE_F2PY=ON, you should use (at least):

• ESMA_cmake v4.37.0

We recommend most external users set -DUSE_F2PY=OFF

We also require CMake 3.24 or higher.

MAPL 2.68.0

This release includes many updates for both MAPL2 and for the upcoming move to MAPL3 as well as fixes for GEOSgcm development

This includes the introduction of a transitional mode to support MAPL3, enhancements to locstreams and tile file reading, and CDash and CI/CD pipelines. and several bug fixes.

Key Highlights:

• MAPL3 Transitional Support: Added the MAPL_SUPPORT_MAPL3 CMake option (OFF by default) to compile MAPL2 as a support library alongside MAPL3, renaming targets with a MAPL2.* prefix.

• Component Updates: Updated components.yaml to match GEOSgcm v12, bumping ESMA_env to v5.21.0 (Baselibs 8.27.0, featuring ESMF v9.0.0b10 and GFE v1.23.0), and ESMA_cmake to v4.36.0 with multiple macOS and f2py fixes.

• CI/CD Enhancements:

  • CDash nightly workflows configured to build and test release/MAPL-v3 from main.
  • Expensive CI is now skipped on draft PRs.
  • Concurrency groups have been added to GitHub Actions to prevent runner limits.

• New Features:

  • Added a "read and bcast" pattern for MAPL_ReadTilingNC4.
  • Simple locstreams can now be created with optional tilelons and tilelats.
  • Added support for creating a halo based on local displacement members (LDE).
  • Python bridge updates to support Python 3.12+, fix Python-side GPU uploads, and support the icx compiler.
  • Guarded IEEE halting mode calls on macOS Flang to resolve missing fe*except symbols.

All testing shows this is zero-diff to MAPL 2.67

From CHANGELOG.md

Fixed

• Python bridge: support for icx, fix GPU upload python side and updated base API to support python 3.12+
• Guard IEEE halting mode calls on macOS flang to avoid missing fe*except symbols when initializing MPI.
• Fixed some warnings with mlc link checker

Added

• Added "read and bcast" pattern for MAPL_ReadTilingNC4
• Added optional tilelons and tilelats to create a simple locstream
• Add MAPL_SUPPORT_MAPL3 CMake option to reduce MAPL2 to a support library for use alongside MAPL3. When ON, the generic layer, gridcomps, Apps, benchmarks, docs, Python bridge, and top-level Tests are disabled; all CMake targets are renamed with a MAPL2.* prefix controlled by the MAPL_TARGET_PREFIX variable. Default is OFF (no change in behavior).
• When MAPL_SUPPORT_MAPL3=ON, the umbrella module in MAPL/MAPL.F90 is renamed from module MAPL to module MAPL2 (and the alias from MAPL_Mod to MAPL2_Mod); use MAPL in hybrid mode is intentionally undefined. use ESMF_CFIOMod is now unconditional in both modes.
• Add .mlc.toml file to configure mlc link checker
• Added a new feature: create a halo based on local displacement members, local-displacement-ensemble (LDE), requested some time ago by Arlindo da Silva
• CDash nightly workflow configured to build and test release/MAPL-v3 from the main branch
• CTest dashboard configuration files (CTestDashboard.cmake, CTestConfig.cmake, CTestCustom.cmake) ported from release/MAPL-v3 to support nightly CI/CD testing

  • Added to workflow.yml, changelog-enforcer.yml, enforce-labels.yml, markup-link-checker.yml, validate_yaml_files.yml

MAPL 2.65.0

This is a new minor release of MAPL.

The main impetus for this release is it is part of a two-part fix for a memory leak found in the GEOSgcm mkiau code (used in Replay). This leak is seen prominently if you run replay for a long time on many cores.

This release also adds a new protection against doing time-averaged History output when the ref_time is incompatible with the frequency and start time in cap_restart. Before, the initial History output would be empty (all MAPL_UNDEF or 0.0) and this could cause unintended consequences down the line. So MAPL 2.65 takes the safe route where it now will halt if this condition is detected.

All tests show this is zero-diff to MAPL 2.64
