COSIMA TWG Meeting Minutes 2025

Meeting Summary & Minutes

Date: May 26, 2025
Attendees: @cbull, @dougiesquire, @anton, @aekiss, @AndyHoggAnu, @pearseb, @helen, @MartinDix, @spencerwong

ACCESS OM3 Config Docs
Chris demonstrated the config documentation system. The docs are versioned, written in Markdown for easy transferability, and will support citability with an automatically updated DOI upon each config release. Chris also proposed generating a full PDF version. The implementation involves a repository with a structured skeleton where the actual documentation is stored in Markdown files.

Current ACCESS OM3 config docs are located here: access-om3-configs/docs at davide/docs-setup · ACCESS-NRI/access-om3-configs · GitHub

New Website Structuring Approach
Chris proposed a new website structure where docs live alongside the code, with the main branch holding general info and config details in separate branches, to minimise redundancy and supports community edits.

Repo Search & Configs Discussion
Andrew explained the use of repo search links in the docs. Chris and Andy discussed dynamic linking, MathJax for equations, and a standardized config subdomain.

Chris emphasized proper work attribution and linking commits to work.

Versioning & Updates
Chris and Andy highlighted the need for flexible versioning to handle updates across releases while ensuring accuracy for older configurations.

Restart Reproducibility
Dougie identified that the Mom symmetric restart reproducibility issue comes from changes ACCESS-NRI have made to the MOM NUOPC cap. Hopefully an easy fix.

Andy inquired about patches, and Dougie confirmed they are in a PR candidate branch, queued for upstreaming.

Incoming MOM6 PR from NCAR

  • There’s an open PR to MOM6 main that impacts OM3
  • Dougie has suggested changes to that PR. One accepted already, one hopefully accepted soon.

OM3 configs consolidation

One API Release:
Anton plans to skip the old COSIMA build system and transition to the new one, as test results were identical.

Action Items

  • Chris: Create a release checklist template for the ocean team on the forum.
  • Dougie: Fix the restart reproducibility issue in MOM symmetric.
