# Performant concurrent distributed GGUF runtime

Status: active benchmark-gated implementation program.

## Objective

Serve the exact pinned GLM-5.2 `UD-IQ1_S` artifact in `reasoning_effort=max` mode across consumer machines with useful measured performance. Dense Llama is a structural fixture; the real multi-node GLM target is the alpha release gate.

See **[GLM-5.2 Max distributed alpha roadmap](GLM-5.2-MAX-ALPHA-ROADMAP.md)** for the target identity, minimum hardware, immutable acceptance matrix, and revised execution order. The 224-GiB figure is an experimental hard-fit floor; recommended topology is 5×64 GiB or 3×96/128 GiB after the required per-node reserve.

## Critical path

```text
Meshnet control plane
  -> versioned gRPC/Protobuf Shard protocol
  -> project-owned standalone C++ worker
  -> small pinned llama.cpp patch stack
```

Transformers/safetensors remains the correctness baseline. vLLM remains an optional complete managed provider and a design donor; it is not forked into the public mesh.

## Planning artifacts

- **[Mandatory Ralph context](RALPH-CONTEXT.md)** — read first in every fresh iteration
- [Task evidence contract](evidence/README.md)
- [Implementation strategy](implementation-strategy.md)
- [Current architecture](architecture.md)
- [PRD](PRD.md)
- [Ralph backlog](prd.json)
- [ADR-0020](ADR-0020-distributed-gguf-runtime.md)
- [Milestones](milestones.md)
- [Issues](issues/)
- [Distributed GGUF research](../../docs/research/distributed-gguf-landscape.md)
- [GitHub follow-up](../../docs/research/distributed-gguf-github-followup.md)
- [vLLM assessment](../../docs/research/vllm-distributed-gguf-assessment.md)

## Ralph execution

Use supervised one-story iterations for this high-risk runtime:

```bash
ralph-tui run \
  --prd .scratch/distributed-gguf-runtime/prd.json \
  --agent claude --model opus \
  --iterations 1 --no-tui --no-setup --verify
```

Inspect the diff, run the story gates, and commit one verified story before the next iteration. Real-model stories require the explicit environment gate and mounted-drive model storage.
