Agenda Items

  • Chris Bull no pre-existing agenda items.

Communication Update

  • Claire Carouge highlighted the move of our ESM1.6 communications from a hidden message to a public topic.
  • Chris Bull clarified the renaming of the thread and encouraged attendees to watch the thread for notifications (click bell down the bottom).

Project Board Review

  • Chris Bull reviewed the ESM 1.6 project board and invited attendees to mention any blockers or issues.
  • No issues / blockers were mentioned.

Experiment Documentation

  • Chris Bull emphasized the importance of documenting experiments, especially those used for production runs in July. This process has begun already, thanks @spencerwong and @pearseb
  • Spencer Wong discussed the creation of a GitHub repository for experiment details and provided instructions for pushing experiment branches.
  • Specifically this branch naming convention <GH-user-name>-<dev/test>-<YYYYMMDD>-<counter> and the use of GH issues for any descriptors. Please see README for further instructions.
  • @pearseb not here today but please add experiment for current spin up experiments to this repo’.
  • Note this is a different GH organisation so you’ll need to get in touch with @clairecarouge / @spencerwong to get access.

General Matters

  • Claire Carouge raised an issue about building and running ESM 1.6, mentioning a runtime error related to generic tracers.
  • Dougie Squire and Harshula discussed potential issues with the build system and configurations and the need for updates on both.
  • Dougie Squire wanted to know which config branch to focus on, this one

Data Management Plan

  • Ian raised a concern about data storage and the potential for data purging on scratch storage.
  • Rachel Law and Tilo Ziehn discussed the need for a data management plan, especially for spin-up and production runs. Only a subset is probably practical to keep on disk the rest can go on tape.
  • Paul Leopardi requested a copy of Chloe’s original data plan for reference.
  • No one is currently assigned to write a Data Management Plan (afterthought: @cbull will ask @ClareCR about next steps?)
  • @Aidan payu has in-built sync support. If we’re in danger of losing important information it should be turned on

Compiler and MPI Updates

  • Harshula expressed the need to use a newer compiler and OpenMPI version for future test runs. Namely openmpi: 4.1.5 / ifort: 2021.10.0. See PR. When is the best time to roll out these changes?
  • No one followed up at standup. Chris would follow up offline.

Action Items

  • Chris Bull to follow up on the sequencing of changes related to the new compiler and MPI version.
  • Rachel Law to provide Paul Leopardi with a copy of Chloe’s data plan.
  • Dougie Squire to review and update ESM1.6 configuration to ensure compatibility.

Closing Remarks

  • Dougie Squire Looks like I won’t have time to raise my hand. I want to update the ocean grid, which will also entail updating the ice grid and remapping weights: link
  • Chris Bull Out of time today, please send agenda items in advance such that we can plan for time as appropriate
  • Chris Bull thanked attendees and closed the meeting. @clairecarouge is hosting next week.
