🚀 Attempted to deploy access-test Prerelease pr69-2 with commit 89c56c9

🖥️ Gadi Deployment ✔️

Usage Instructions

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

• 2026.01.002 as a Release (when merged).
• pr69-2 as a Prerelease (during this PR).

This Prerelease is accessible on Gadi using:

module use /g/data/vk83/prerelease/modules
module load access-test/pr69-2

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/1.1/spack in the access-test-pr69-2 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.

• access-nri/spack on branch 1.1
• ACCESS-NRI/upstream-spack-packages version access/v1.1
• access-nri/access-spack-packages version 2026.05.003
• access-nri/spack-config version 2026.05.004
