PROFILE
Dimitris Menemenlis
During June 2025, D. Menemen worked on the MITgcm-contrib/ecco_darwin repository, focusing on modernizing the build system and streamlining the Gulf of Maine (GoM) regional model workflow. They reintroduced and updated build tooling for macOS, removed legacy v4r5 artifacts, and reorganized the codebase for improved maintainability. Using Fortran, Python, and shell scripting, Menemen unified GoM/llc90 model configuration and consolidated input data, reducing misconfiguration risks. They also deprecated and removed sea ice and shelf ice components to simplify the setup. This work enhanced reproducibility, reduced maintenance overhead, and prepared the codebase for more robust testing and continuous integration.

Jun 1, 2025June 2025 monthly summary for MITgcm-contrib/ecco_darwin focusing on business value and technical achievements. Key features delivered: - Build system modernization and codebase cleanup for GoM region: Reintroduced and modernized build tooling for macOS GoM regional simulations, added compile-time size references, and streamlined codebase by removing legacy v4r5 artifacts and reorganizing files. Notable commits include f355c01c2c7a0b2dc601c44d231eefea0ffa3c18 (adding back cogapp.py), 6ac4946bda607ae52deea6b694e103d1660c791a (compile-ready note), 4a522aa21158668ed2082eda59e8b043b4a37da1 (removing code_darwin_v4r5 and reorganizing), and a851d78b74c7c50bca59f627748081b43406ff81 (removing code_v4r5). - GoM/llc90 model input, configuration, and data management overhaul: Established and consolidated the GoM/llc90 model configuration with initialization files and input data in a unified structure for v4r5_v2, including calendar, forcing, and parameter configurations. Key commits include 5d76c00610bc59df656543044153ac8647256bc6 (regenerating code directory anew), e451fd0d735d57e8563464ecaa280072d7875186 (consolidating inputs in a single directory), ba3a1e59b644725dd5608576bcff806c9b928e05 (bringing files from v06/1deg/input_v4r5_v2), and 02a0388bd63a5cfd47775ccdd53a42aeafdbe339 (initial input merge attempt). - Removal of sea ice and shelf ice components from GoM region configuration: Deprecate and remove sea ice and shelf ice packages and their configuration files from the GoM region to simplify the model setup. Commits include e1a5834dd8e47451f9a516a1a101c2d9a03c6866 (removing seaice and shelfice files and related artifacts) and 842b90242cbdeb3126f5fef10f173897729779be (removing data.seaice, shelfice, salt_plume, and exch2). Major bugs fixed: - Resolved build fragility by reintroducing and modernizing build tooling for macOS GoM simulations and pruning legacy v4r5 artifacts. - Reduced misconfiguration risks by consolidating inputs and removing deprecated ice configurations, thereby preventing runtime/configuration errors. Overall impact and accomplishments: - Significantly improved maintainability and reproducibility of the GoM/darwin workflow with a cleaner codebase, unified configuration, and streamlined data management. - Reduced maintenance burden and readiness for testing/CI by removing obsolete components and clarifying input structure. Technologies/skills demonstrated: - Build tooling modernization, codebase hygiene, and configuration management for scientific software. - Data management consolidation, repository hygiene, and careful refactoring to support GoM region workflows.
