AI-generated CUDA kernels cause silent bugs in deep learning training

By PulseAugur Editorial · [1 sources] ·

AI-generated CUDA kernels, intended to accelerate deep learning computations, have been found to introduce subtle and hard-to-detect bugs. These kernels, which passed NVIDIA's SOL-ExecBench benchmark, failed in real-world training scenarios, leading to issues like loss divergence. The problems stem from precision errors in bf16 accumulation for embedding gradients, which are masked by certain optimizers like AdamW or specific datasets, making them difficult to diagnose. AI

IMPACT AI-generated code for hardware acceleration can introduce subtle bugs that are difficult to detect, potentially hindering research and development.
