warp.config.cuda_arch_suffix

warp.config.cuda_arch_suffix: str | None = None

CUDA architecture suffix for kernel compilation.

Controls whether architecture-specific or family-specific suffixes are appended to the --gpu-architecture flag passed to NVRTC.

Parameters:

cuda_arch_suffix – One of {None, "a", "f"}. None disables suffixes (default, current behavior). "a" enables architecture-specific features (requires sm_90+). "f" enables family-specific features (requires sm_100+ and CUDA 12.9+).
