Twenty CUDA .cu prototype files from the PyC kernel lab. The collection covers baseline and experimental matmul, Ada FP32/Tensor Core variants, Hopper WMMA BF16/FP16 variants, asynchronous staging, CTA/warp/K-stage experiments, and cuBLASLt control lanes.

These are source artifacts for inspection, compilation, and performance engineering—not precompiled model weights and not a claim of universal benchmark superiority. The 19 documented lab lanes are:

The source files are organized by prototype family; several documented lanes share one parameterized .cu implementation. See the companion performance Space for the optimization story and selected measurements.
