1. Summary:

Added documentation about the building and deployment process for ACCESS-ESM1.6

2. Issues Addressed:

3. Dependencies (e.g. on payu, or model)

This change requires changes to (note pull request(s) where relevant):

  • workflow manager (payu):
  • model deployment (ACCESS-ESM1.6):
  • model component or library dependency:
  • input workflow:

4. Ad-hoc Testing

What ad-hoc testing was done? How are you convinced this change is correct (plots are good)?

Documentation only. No testing done. Relying on build preview in PR to correct formatting.

5. CI Testing

  • !test repro has been run
  • N/A: documentation only

6. Reproducibility

Is this reproducible with the previous commit? (If not, why not?)

  • Yes
  • No - !test repro commit has been run.

8. Manifests

Have you changed the executable, the input files and/or the restart files?

  • Yes
  • No

If yes, have you updated the manifests?

  • Yes
  • No

To update the manifests, run payu setup (in a cloned copy of your feature branch) with reproducibility tests turned off:

manifest:
  reproduce:
    exe: false
    input: false
    restart: false
runlog:
  enable: false

Then commit the newly created manifest files (under manifests/) only to the branch for this PR.

7. Documentation

Is the documentation updated?

  • Yes
  • N/A

9. Merge Strategy

  • Merge commit
  • Rebase and merge
  • Squash

@atteggiani The config docs for ESM1.6 fail to deploy with the preview. Does it need all the PR previews to work in order to deploy? I'm happy to go and fix PR 252, just making sure that should solve the problem before investing time.

Yes it needs all PR previews to work, unfortunately.
If the fix takes time, you might try writing a line with !no-pr-preview in the body of the PR (PR #252 in this case). It should not trigger that PR preview. I haven't tested this properly due to RTD changes so it might not work, but it's worth a try.
It needs to be the first line of the PR body.

Then you would need to re-trigger this PR. You cannot simply retrigger the build manually, so you'll have to add a new commit or amend (no edits) and force push the latest one.

PR #252 was fixed and the preview workflow ran from #252 has now created a preview (dismiss the failed build in this PR).

@chrisb13 I'll have a look at the links you shared.

Sure thing, @anton-seaice might be a helpful person to canvas too.

Added information on required repositories and building methods for ACCESS-ESM1.6.
If you need to modify the source code for ACCESS-ESM1.6, you will need to use the Spack infrastructure to create your own build. There are two ways to do so (on GitHub or locally) both with benefits and limitations.
In order to build your own version of ACCESS-ESM1.6, you will need read access to the following repositories:

Done. But I have completely redesigned the build page.

A couple of comments, but otherwise seems good, thanks.

…higher up in mkdocs.yml

Got tired of having to scroll down or search for the nav entry when it's the bit we modify the most.

Sorry a bit of a chaotic review, I can have another look as needed


## Software structure

ACCESS-ESM1.6 being a Earth System model, it is constituted of several model components, each residing in its own repository on GitHub. In addition, some model components need other utilities at compilation time that are stored in separate repositories. This results in a complex software structure involving a large number of repositories:

## Building ACCESS-ESM1.6 using the deployment infrastructure

This is the recommended method to build ad-hoc versions of ACCESS-ESM1.6 because it does not require users to have access to all the repositories, it handles the build automatically and it provides traceability and shareability of the deployment.

It needs an introduction sentence

e.g. It is possible to:

  • semi-automatically build ACCESS-ESM1.6 using github actions to trigger a build
  • and make that available to build on gadi.
  • this is good because it requires much less setup than using spack directly.

# Build infrastructure

Most users of ACCESS-ESM1.6 will not need to build the model. Released versions of the model are deployed by ACCESS-NRI to Gadi and available to users. Check the [Deployment page](/documentation/docs/pages/infrastructure/Deployment.md) to learn about available deployments. If you require your own build of the model, typically because you need to modify one or several model components, you will find the required information on this Builing page.

Do we need to define release and deploy, we use them both, slightly interchangeably

- Deployment: pages/infrastructure/Deployment.md
- Building: pages/infrastructure/Building.md
- Git practices: pages/infrastructure/Git-practices.md

## Local build of ACCESS-ESM1.6

The Spack infrastructure allows you to create your own local build on _Gadi_ for ACCESS-ESM1.6. Once setup, this might be faster than using the deployment infrastructure, especially when you want a lot of small incremental builds during development.

There are development releases (identified with a `dev_` prefix to the date tag) and full releases (identified with only a date tag). We recommend new users start with the newest full release (i.e., with the most recent date tag).

These builds are optimised for the Sapphire-Rapid hardware from Intel (i.e., the *normalsr* queue), and may not run on Cascade-Lake (i.e., the *normal* queue) or older hardware.

I'm pretty confident it would run fine on normal. I can't see any HW specific optimisation going on

# Deployment

All released versions of ACCESS-ESM1.6 come with a pre-deployed build on _Gadi_. Deployed builds are stored under the project `vk83` (hence requiring [membership to this project](https://my.nci.org.au/mancini/project/vk83/join) for access). You can see all deployed builds via:

Mostly the words a "release version" would refer to a configuration, not a model exe

I think the point here is - release configurations use a certain deployment of the model code. Mostly users wouldn't mess with that.

Up to date configs will use the latest deployment, the older ones are kept for folks who are running experiments based on older configurations

this project membership is surely self evident by this point, its where payu is available from

This isn't really a page for new users. What we actually recommend is that new users use a released configuration
