Usage Instructions

access-om2, defined in ./spack.yaml, will be deployed to Gadi as:

• 2025.12.000 as a Release (when merged).
• pr127-2 as a Prerelease (during this PR).

This Prerelease is accessible on Gadi using:

module use /g/data/vk83/prerelease/modules
module load access-om2/pr127-2

When using the above modules, the binaries shall be on your $PATH.

For advanced users, this Prerelease is also accessible on Gadi via /g/data/vk83/prerelease/apps/spack/0.22/spack in the access-om2-pr127-2 environment.
Due to inode-saving measures, one will have to manually untar the environment metadata before environment activation with tar -xf .spack-env .spack-env.tar. It will require one to have write privileges.

Configuration Information

This Prerelease is deployed using:

• access-nri/spack on branch 0.22
• access-nri/spack-packages version 2817e9e41a6142cb617b216e53c7f3fef5a8da52
• access-nri/spack-config version 2025.08.000

If the above was not what was expected, commit changes to config/versions.json in this PR.
