Commit Queue Requirements:

• This PR addresses a relevant WM issue (if not, create an issue). (Placeholder issue seeking guidance for optimizing model run time on WCOSS2 for RRFS application #3023)
• All subcomponent pull requests (if any) have been reviewed by their code managers.
• Run the full Intel+GNU RT suite (compared to current baselines), preferably on Ursa (Derecho or Hercules are acceptable alternatives). Exceptions: documentation-only PRs, CI-only PRs, etc.
  • Commit log file w/full results from RT suite run (if applicable).
  • Verify that test_changes.list indicates which tests, if any, are changed by this PR. Commit test_changes.list, even if it is empty.
• Fill out all sections of this template.

Description:

This PR brings in some needed code speedups for the RRFS system.

1. a ccpp-physics change that speeds up the RUC LSM
2. a stochastic-physics change that limits soil T/q perturbations to initial time, and adds some OMP directives to enhance performance on multiple threads.

Commit Message:

* UFSWM - 
  * stochastic-physics: https://github.com/NOAA-PSL/stochastic_physics/pull/95
  * UFSATM - https://github.com/NOAA-EMC/ufsatm/pull/1057
    * ccpp-physics - https://github.com/ufs-community/ccpp-physics/pull/351
 

Priority:

• Critical Bugfix: Reason
• High: Trying to get this code optimization incorporated into the pre-implementation RRFS parallel as quickly as possible.
• Normal

[MatthewPyle-NOAA]

CCPP-physics change has been merged now.

[jkbk2004]

@MatthewPyle-NOAA new hash for stochastic physics rrfsv1 branch is NOAA-PSL/stochastic_physics@b8eda18

[jkbk2004]

@MatthewPyle-NOAA still in draft mode?

[MatthewPyle-NOAA]

Was just about to change it, @jkbk2004

[MatthewPyle-NOAA]

Reverted it to a draft, as planning to include one more ccpp-physics change with this umbrella change.

[MatthewPyle-NOAA]

@jkbk2004 I've put updated answers for two tests (control_lndp_debug_intel and rap_lndp_debug_intel) onto Hera/Ursa under /scratch4/NCEPDEV/fv3-cam/Matthew.Pyle/rrfs_baseline_updates/ On WCOSS these now are under a 20260227 baseline date.

[MatthewPyle-NOAA]

@jkbk2004 We were thinking of adding another bug fix to this umbrella PR. The change is in atmos_cubed_sphere. But if you feel like this one is too far along, we can handle it with a follow on PR.

[jkbk2004]

@MatthewPyle-NOAA Yeah, incremental update will be easier.

[MatthewPyle-NOAA]

@jkbk2004 Okay, should be back to what you tested on Hercules now.

[jkbk2004]

@MatthewPyle-NOAA just note that .gitmodules points to the fv3 feature branch. I am ok if you want to go ahead to merge after revert change in gitmodules.

[MatthewPyle-NOAA]

@jkbk2004 Just merged the UFSATM PR - will update things a bit later (have some meetings soon).

[MatthewPyle-NOAA]

@jkbk2004 What do I need to do to move this one along? Not sure whose approval I need. Thanks!

[jkbk2004]

@MatthewPyle-NOAA you can go ahead to merge.

[MatthewPyle-NOAA]

@jkbk2004 I see a "Merging is blocked" since 2 approving reviews are required.

[BrianCurtis-NOAA]

Everything seems to point to where it needs to. Approved.
