# Conch Triton Kernel Standard Library

- Repository: `stackav-oss/conch`
- Source: [stackav-oss/conch](https://github.com/stackav-oss/conch)
- Package: [conch-triton-kernels](https://pypi.org/project/conch-triton-kernels/)

## Route Fit

Use Conch as a high-quality open Triton kernel reference for direct-file mode
and vLLM-adjacent serving kernels. It is useful when the task needs a PyTorch
reference, unit test, microbenchmark, launch wrapper, or standalone Triton file
that can be adapted into `.humanize/triton-agent/` harnesses.

## What To Inspect

- Paged attention, varlen attention, rotary, RMSNorm, KV-cache, and quantized
  utility kernels.
- `tests` for correctness tolerances and edge cases.
- `benchmarks` for warmed timing and direct wrapper invocation patterns.

## DCU Use Notes

Conch is useful because it is closer to direct-file Triton work than framework
backend code. Still verify ROCm/DCU behavior with local profiler names, cache
entries, and target `gcnArchName`; do not copy tuning constants blindly.

## Query Hooks

```bash
python3 scripts/query.py "conch triton paged attention" --type source-reference --compact
python3 scripts/query.py "conch rmsnorm rotary fp8" --type source-reference --compact
python3 scripts/query.py "conch direct file harness triton" --type source-reference --compact
python3 scripts/get_page.py ref-stackav-conch
```
