cuda skillA

cuda is agent-read markdown (skill) from tongminglaic/ako4x: CUDA C++ (.cu) kernel reference — TVM-FFI direct-export vs Python-binding entry points, the chevron-launch null-stream pitfall under CUDA-graph capture, the sm_100 fp8→bf16 cvt PTX gap, the load_inline name-cache trap, and the __launch_bounds__ register-spill lever. Also the single-source for generic per-call-overhead / CUDA-graph-capture / PDL theory (Waves-Per-SM decision table) regardless of DSL. Use when writing or debugging hand-written CUDA C++ kernels, or whenever you need generic CUDA-gr.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add tongminglaic/ako4x/cuda@git:20260531.0fd4b5f
Exact content
mdr add tongminglaic/ako4x/cuda@sha256:cc477684ea80d6e6

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
