Helion autotuner adds NVIDIA CompileIQ ptxas controls to kernel search

PyTorch Blog says Helion's autotuner can now evaluate pre-tuned Advanced Control Files from NVIDIA CompileIQ alongside its kernel configurations.

The ACFs set ptxas compiler controls such as register allocation, instruction scheduling and code-generation heuristics, which are left at defaults in kernels shipping today.

The post says the joint search improves kernels that were already autotuned, though it does not give the size of the gains in the excerpt.
