Yuchen Chen developed GPU-accelerated radiative cooling calculations for the SWMFsoftware/BATSRUS repository, focusing on performance optimization for scientific computing workloads. By porting the radiative_cooling() routine to GPUs using OpenACC directives and parallelizing loops in ModHeatConduction.f90, Yuchen enabled both linear and nonlinear radiative cooling cases to leverage GPU vectorization and loop collapsing. This work established a scalable, high-performance workflow for radiative cooling computations, addressing the need for faster simulations on modern HPC architectures. The implementation, written in Fortran and utilizing GPU computing techniques, demonstrated a deep understanding of both domain-specific algorithms and the practical challenges of scientific code acceleration.
