AscendOptimizer: Episodic Agent for Ascend NPU Operator Optimization
🤖AI Summary
Researchers introduce AscendOptimizer, an AI agent that optimizes operators for Huawei's Ascend NPUs through evolutionary search and experience-based learning. The system achieved 1.19x geometric-mean speedup over baselines on 127 real operators, with nearly 50% outperforming reference implementations.
Key Takeaways
- →AscendOptimizer addresses the knowledge gap in optimizing for Huawei's Ascend NPUs compared to the well-documented CUDA ecosystem.
- →The system uses profiling-in-the-loop evolutionary search to discover optimal tiling and data-movement configurations from hardware feedback.
- →It creates a retrievable experience bank by systematically de-optimizing kernels to generate instructive optimization trajectories.
- →Testing on 127 real AscendC operators showed 1.19x geometric-mean speedup with 49.61% of operators outperforming references.
- →The approach demonstrates how AI can bootstrap domain expertise in specialized hardware optimization where documentation is limited.
