12 Commits • 2 Features
Mar 1, 2025March 2025 focused on delivering high-value, maintainable EOS-related features for LANL/singularity-eos, with emphasis on numerical accuracy, on-device reliability, and streamlined build tooling. Key work included substantive enhancements to FlooredEnergy for extended EOS calculations and testing robustness, a safety- and maintainability-focused refactor of diff_pressures, and targeted on-device utilities and test guards to improve reliability and testing coverage. In addition, legacy build infrastructure was modernized by removing Makefiles to reduce build friction and align with modern automation practices. The combination of feature work, reliability improvements, and build-system modernization delivered tangible business value through improved numerical accuracy, safer device code, easier maintainability, and faster CI cycles.
