AI inference optimized with multi-megakernel approach, outperforming single kernels

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new framework for optimizing streaming inference in AI models by strategically composing multiple megakernels rather than relying on a single monolithic one. This approach, tested across NH-TTS, Qwen3-TTS, and Llama-1B models, found that optimal performance often involves two to four specialized megakernels or a fully conventional graph execution. The framework predicts the best configuration by simulating tile and event graphs, avoiding full end-to-end runs. For the NH-TTS model on an H100 NVL GPU, this method achieved a 21.4% reduction in time to first audio and a 28% increase in throughput compared to a single megakernel design, and significantly outperformed conventional TensorRT execution.
