Jun 1, 2025Month: 2025-06 – FESOM/fesom2. Concise monthly summary highlighting key features delivered, major bugs fixed, overall impact, and technologies demonstrated. Focused on delivering business value and technical achievements with concrete deliverables and commit-level traceability. Key features delivered: - Uninstall and clean-up capabilities: added uninstall support and a --clean option to the configure script to remove all build targets before install. (commits cd5d1a19fc258ec931ff976b4056cbe978c248bd; a5bd4411477350b71e4f6218090732ab88964439) - Build system enhancements and testing infrastructure: improved build configurability with optional mesh part builds (GNU/Intel), disabled default meshpartitioner, bumped cmake minimum version, added cmake/ctest based testing, and exposed mesh_part as a root cmake target. (commits f1c8e2c847e7a6f735fadc83b3167f4104cd15d4; 8b5511af173094cec3706f108b3458c11a35cbe7; f74880ddce9cf5460a25fbc84f47ebc4fa4a746b; ea9e27cdcc2eac0ba3bd33e154673609f38b7dc2; f3a5ad482ef18b35dafd4fda7c94b6a3710bcbc0) - MeshPart build/install improvements and CI wiring: added install abilities to meshpart, downgraded cmake version requirement, removed mesh part build from src, enabled old-style build via configure in mesh_part dir, and linked fesom_meshpart as fesom_ini.x for CI tests. (commits 007fe3fe56b5e88cfc57cf9ac3039f82f894741a; 4a2d7e781b11c110927b89cb6fff4e846059a5b7; 8c29888403cb3f84ed67e471bef9325165f3feb7; 52c8c3633feb4a7f45e34f2286833281d00ad4b5) Major bugs fixed: - Namelist/forcing formatting and test data fixes: corrected forcing path handling, removed trailing year, updated templates, added test existence checks, pruned test data dirs, and stabilized tests.

(commit b3187cfeea9eb35a9992c8e2cf251dfa249b0f20) - Encoding and label/end statement fixes: standardized to UTF-8 encoding and corrected labeling/end statements across modules to improve reliability. (commits 591f70ccea8ea59a1a737278b45945a468a073e9; 3405ba3f719a59adfccdd798b3bb8d8833d2bced; 0dbe6a2c59ce9dffcbdb3e4041bce6e911299db3; c3971796880ffb8a215187f1f6efa5d1787103f8) Overall impact and accomplishments: - Significantly improved build reliability and test stability, reducing regression risk across configurations and mesh-part integration. The uninstall/clean flow simplifies deployment, while the enhanced CI/test wiring for meshpart accelerates feedback cycles. The changes collectively shorten time-to-release and improve reproducibility for validation suites. - Business value: easier installation and cleanup for customers, more robust and configurable build pipelines, faster iteration cycles, and reduced maintenance burden due to standardized encoding and corrected labeling. Technologies and skills demonstrated: - Build systems: CMake, cmake/ctest, and configuration scripts. - CI/testing: test automation integration and root-target exposure for mesh_part. - Scripting and automation: install/uninstall workflows and test-data management. - Quality and standards: UTF-8 encoding, consistent module labeling, and robust test data handling.
