During a two-month period, GSS enhanced the lanl/singularity-eos repository by expanding multi-dimensional data handling for pressure, bulk modulus, and entropy calculations. Leveraging C++ and Fortran, GSS introduced stride-aware and lambda-enabled interfaces, enabling robust, cross-language computation for complex scientific datasets. The work included refining API signatures, standardizing naming conventions, and ensuring correct parameter passing between Fortran and C, which improved both maintainability and correctness. GSS also addressed a critical bug in the Fortran interface and applied code formatting and refactoring for long-term stability. These contributions deepened the repository’s support for high-performance, scalable equation of state modeling workflows.
