NVIDIA CompileIQ 与 PyTorch Helion 联合搜索内核与编译器参数
写 CUDA 内核调优到极限的朋友看这个：NVIDIA CompileIQ 接入了 Helion 自动调优器，编译器参数也能一起搜了。
PyTorch Helion 的自动调优器传统上只搜索 tile 形状、warp 数量等内核配置，ptxas 编译器选项如寄存器分配通常保持默认。NVIDIA CompileIQ 的 Advanced Control Files（ACFs）现在直接集成进 Helion，让内核配置与编译器控制在同一个联合搜索空间中被评估。官方称这能在已充分调优的生产内核上继续获得额外加速，且开发者无需深入编译器专业知识。
Squeeze extra performance out of GPU kernels that are already autotuned to the limit by diving below the kernel level into compiler controls.
@nvidia CompileIQ and PyTorch Helion have united two distinct optimization layers into a single joint search space. While traditional autotuners search tile shapes, warps, and pipeline stages, ptxas compiler decisions like register allocation and fine-grained scheduling are typically left at default settings.
With CompileIQ’s Advanced Control Files (ACFs) integrated directly into Helion’s autotuner, developers can jointly evaluate kernel configurations and compiler controls, unlocking significant speedups on highly optimized production kernels without requiring deep compiler expertise.
