Xe-Forge: Multi-Stage LLM-Powered Kernel Optimization for Intel GPU
Xe-Forge is a new multi-stage pipeline designed to optimize kernel performance for Intel GPUs. It automates the repetitive process of applying low-level optimizations to deep learning algorithms, significantly reducing the manual effort required. The system has demonstrated impressive speedups across various kernels, showcasing its potential to streamline algorithm deployment on new hardware accelerators.
- ▪Xe-Forge automates the optimization of Triton kernels for Intel GPUs through a multi-stage process.
- ▪The system applies up to nine optimization stages, driven by a Chain-of-Verification-and-Refinement agent.
- ▪Evaluation results show a 1.17x geometric mean speedup over PyTorch eager, with 67% of kernels improving.
