March 2026 monthly summary for ACCESS-NRI/ACCESS-OM3: Delivered stability and performance improvements through targeted dependency upgrades and a hardware architecture upgrade. Implemented dependency version bumps across spack.yaml and OM3 components to align with newer releases, and updated OM3 main components to ensure compatibility and leverage stability improvements. Upgraded the target architecture from x86_64 to x86_64_v4 to enable newer hardware features and optimizations. A formal release baseline was established to support reproducible deployments. No major bugs were reported this month; no regressions observed in CI or deployments. Business value: improved compatibility with current and future runtimes, smoother deployment processes, and potential performance gains on newer hardware. Technologies/skills demonstrated: dependency management with Spack, release engineering and versioning, cross-repo coordination, and architecture-targeted updates.

January 2026 monthly summary for ACCESS-NRI/spack-packages: Delivered two key features to enhance build reliability and compatibility: Access-ESM1.6 Spack manifest updated for master-branch builds, and CICE5 package upgraded to version 2026.01.000 with updated build configurations and dependencies. No critical bug fixes recorded this month; focus was on stabilizing the build pipeline, improving reproducibility, and readiness for downstream deployment. Impact: improved environment reproducibility, reduced build failures, and smoother user adoption. Technologies demonstrated: Spack manifests, versioning, dependency management, and build-system configuration in a collaborative repository.

August 2025 monthly summary focused on release alignment and build reproducibility for the OM3 model across the ACCESS-NRI/spack-packages repository. Key work included establishing stable branches and version tags for CICE, MOM6, WW3, access3-share, and access3 packages, and updating the build system to reference the latest model component versions. No major bugs reported this month. This work enables reliable, repeatable environments and smoother downstream integration.
