Feb 1, 2025February 2025 — ISSMmonthly summary for ISSMteam/ISSM. This month focused on stabilizing builds, reducing maintenance, and strengthening CI/test reliability across macOS and Linux environments. Key outcomes include: - MacOS build stability: Temporarily pin MPICH to work around latest macOS SDK issue, enabling reliable local and CI builds. - Cluster and dependency cleanup: CCR cluster class corrections; gaijin cluster decommissioned; removed GSL and QUESO from Dakota dependencies; Xcode flags cleaned up to simplify builds. - CI/test reliability: Ensure GSL is available for CoDiPack and ADOL-C tests; corrected compiler environment variables in GitHub workflows; copied FC to F77 and F900 for workflow compatibility. - Dataset and scripting improvements: Updated DownloadExamplesDatasets.sh; removed outdated Python install scripts; moved dataset wget steps to temp files; switched to system curl to reduce vendored tooling. - Quality and hardening: Suppressed self-signed certificate errors during TLS validation; verified explicit compiler settings; fixed typos across code/docs. Overall impact: These changes reduce maintenance burden, decrease CI/build flakiness, and accelerate experimentation with datasets and tests, while improving security and consistency across environments. Technologies/skills demonstrated: MPICH/macOS SDK handling, GSL/QUESO dependency management, Dakota integration, Xcode flags, GitHub Actions workflows, Fortran compilers (FC, F77, F900), curl, wget, Bash scripting, TLS hardening.
