Mianbi Intelligence and OpenBMB released ForgeStencil, the world's first AI system for Stencil optimization. It automates hotspot analysis, kernel generation, and deployment without human intervention. In one week, it optimized over 100 industrial applications, achieving 2.35x geometric mean acceleration under fp32 and 1.95x more under mixed fp16. It accelerated real software like hypre by 3.86x and minisweep by 5.78x. Open-sourced on GitHub.
