Apr 1, 2025April 2025 Monthly Summary for AutoPas/AutoPas focused on stabilizing macOS builds and strengthening cross-platform CI. Delivered targeted fixes for macOS compilation and expanded macOS CI coverage, enabling reliable builds and faster feedback on Apple hardware. Key achievements: - MacOS compilation compatibility fixes: implemented to compile with Apple Clang 17.0.0 and GCC, by adding explicit casts for enum switches and a workaround for _Alignof in recent system headers (commits 3b77c36e691b5a25ee55a79bcab4e1ffd97994ee; 38fd226c74406aedd30487bd2a35fd3a7b003dc1). - CI/CD macOS pipeline enhancements: added a macOS-focused build/test job for the md-flexible example and improved workflow naming for clarity and maintenance (commits 7b51b05bf7dace74f811b1eb28ee2b30bc533d0b; b5edb1ca75c64ab7f016759babee887b74017957). Overall impact: more robust macOS builds, faster feedback, and broader CI coverage, reducing platform-related build issues and accelerating developer productivity. Technologies/skills demonstrated: C++, cross-platform toolchain compatibility (Apple Clang 17.0.0, GCC), enum handling with explicit casts, _Alignof workaround, and GitHub Actions CI workflow configuration and naming conventions.

Mar 1, 20252025-03 Monthly Summary for AutoPas/AutoPas: Delivered a build-optimization feature by implementing conditional linking of the pmt library based on the energy measurement flag AUTOPAS_ENABLE_ENERGY_MEASUREMENTS. This change ensures the pmt library is only linked when energy measurements are enabled, reducing build complexity, binary size, and potential runtime dependencies in configurations that do not require energy measurements. Resulting commit 7e3fe8c841b5c04264adc0970d92d9e3797a4c90 documents the approach and justification.
