Commit 'test_changes.list' from previous step

Description:

This pull request contains changes to generalize atmospheric component of the UFS Weather Model:

The reorganization of the repository is to achieve the following goals:

Move dynamical core specific code into subdirectories.
Move common code (e.g. physics) into shareable, cross-dycore, higher-level directories. This is outlined in Figure 1 of the "Tiger Team" report.

Refactor the CMakeLists to build an atmospheric component with either an FV3
or MPAS dynamical core.
Add CMakeLists.txt to build MPAS core_atmosphere component. The CMake recipes from the "MPAS atmospheric core" were adapted to work in the UFS build system.
Modify CCPP physics CmakeLists.txt to build independent MPAS/FV3 couplings to the physics.
Create "stub" mpas infrastructure. This includes stubs for the MPAS atmospheric component driver and overlaying NUOPC cap.

With these changes, the MPAS dynamical core builds within UFS.
Next steps, build atmospheric driver for MPAS, which includes creating new typedefs for coupling between the CCPP and MPAS.

Commit Message:

* UFSWM - Modify build scripts to select which dynamical core to build for the UFS.
  * FV3 - Reorganize into dynamical core specific subdirectories. Modify build systems for multiple dynamical cores. Bring in

@dustinswales It looks like you had a bunch of changes but a force push removed almost all of them. If you intend to work on this PR for a bit, please move it to a draft form until it's ready to be reviewed by the code managers.

@BrianCurtis-NOAA Sorry, I was doing some last minute cleanup. All is back now.

BrianCurtis-NOAA

I think that we will need to adjust rt.sh and the other .sh scripts in the tests directory to use MPAS.

I don't see any new tests files either, so you'll want to bring those in.

Is there a reason this is commented out currently?

It's just a placeholder for the timebeing.
The NUOPC pieces for MPAS will be added later, when the underlying atmospheric component work on MPAS is further along.

dustinswales · 2024-10-07T15:41:01Z

I think that we will need to adjust rt.sh and the other .sh scripts in the tests directory to use MPAS.

I modified default_vars.sh and added a new "MPAS build only" test to rt.conf. If there are other places that need modification, please let me know.

I don't see any new tests files either, so you'll want to bring those in.

There are no new test files at the moment.

FV3

This submodule pointer update seems to be wrong. If I click on the changes, I get taken to a update of 22 files all within the NCAR fv3atm fork - should this PR not update the code in the noaa-emc fv3atm? Maybe I am missing something (it's late).

I would suggest export MPAS=false here in export_fv3 so both aren't true. Making a separate export_mpas () is one option. If you want many of the same settings while turning on MPAS-A, it may be more concise to set:

export_fv3 export FV3=false export MPAS=true

in a regression test until there are defaults to set.

I do not see RUN step that executes the ufs-model executable built with this COMPILE step. How do we even know the mpas model is compiled correctly. Do you plan to add at least one regression test for ufs with mpas core?

Okay, I see this question has been already asked in one of the previous comments, and the answer was no. I'm now confused, but I do not see what we get by making these changes in the ufs-weather-model at this time. We can discuss the corresponding PR in the fv3atm and if it's necessary merge it, but why updating ufs-wm without any tests is necessary

-D32BIT=ON is build flag used to build fv3 dycore using single-precision reals as a default. Is it used in MPAS core? I do not see it used in any mpas CMakeLists.txt. If it's not used, it should be removed from this COMPILE step.
