LLM-Based Porting of Optimized C++ to CUDA Through Deoptimization and Reoptimization

Daichi Mukunoki, Ryo Mikasa, Shunichiro Hayashi +2

When porting high-performance computing (HPC) code from CPU to GPU, CPU-oriented optimizations may obstruct LLM-based CUDA translation. We design and evaluate a Deopt-Reopt workflo…
