Worked on the IAS-Astrophysics/athenak repository to enhance the reliability and efficiency of astrophysics simulations using C++ and high-performance computing techniques. Addressed a critical bug by correcting the Spectre BBH ID glob path, which resolved startup errors related to data loading. Introduced a timing mechanism to measure interpolation during initial data loading, providing visibility into performance and enabling targeted optimizations. Refactored the adaptive mesh refinement condition to use the correct pointer, improving the accuracy and stability of simulation setup. These changes collectively reduced startup issues, improved data-loading accuracy, and enabled faster, more reliable simulation cycles for research workflows.
