New CudaPerf framework enhances CUDA kernel generation with structural rewards

By PulseAugur Editorial · [2 sources] ·

Researchers have developed CudaPerf, a new reinforcement learning framework designed to improve CUDA kernel generation. This framework goes beyond traditional speed and correctness metrics by incorporating structural properties of code, such as memory coalescing and synchronization patterns. CudaPerf operates in two stages: offline pairwise ranking and online RL training with iterative refinement, utilizing a unified reward signal. Evaluations show CudaPerf significantly outperforms existing methods, including Qwen 3 32B and CUDA Agent, by achieving substantial improvements in speedup and correctness for both C to CUDA and PyTorch to CUDA transformations. AI
