# ada_gemm

Ada-focused FP32 shared-memory GEMM prototype with standalone correctness and timing harness.

This repository contains the standalone CUDA source for the `ada_gemm` lane from
 the PyC kernel lab. It is a source artifact for inspection and benchmarking;
it is not a precompiled binary and the result below is not a universal ranking.

## Performance

| Kernel | GPU / architecture | Shape | Best recorded result | Evidence |
|---|---|---|---|---|
| `ada_gemm` | not recorded | not recorded | Not measured in the published campaign | No published performance receipt was found for this lane. |

![Performance plot](performance.svg)

The result is reported with the original campaign's timing and correctness
context. Compare kernels only when GPU, CUDA version, matrix shape, warmup,
repeats, and reference/correctness mode match.

## Source

- `kernel.cu` — copied from `kernels/prototypes/ada/gemm/kernel.cu`.
- Original lane tags: `cuda, matmul, ada, sm89, prototype`.
