# Platform Configurations

Each `.env` file in this directory describes one accelerator platform.
They are meant to be sourced by benchmark scripts through
`scripts/common/platform.sh`, not executed directly.

## Usage

```bash
# Default platform for the current machine
bash experiments/dsv4_p800_sglang/run_bench.sh

# Explicitly select a platform
PLATFORM=kunlun_p800 bash experiments/dsv4_p800_sglang/run_bench.sh
```

## Current platforms

| File | Chip/Accelerator | Engine | Notes |
|---|---|---|---|
| `kunlun_p800.env` | Kunlun P800 XPU | `sglang-xpu` | Docker-based SGLang serving image |
| `nvidia_h200.env` | NVIDIA H200 | native vllm/sglang | Host virtual environments |

## What belongs here

- Chip/accelerator identity (`CHIP`, `ACCELERATOR`, `HARDWARE`).
- Device selection environment variables.
- Platform-wide paths that rarely change (model root, default port).
- Container image / interpreter paths for Docker-based platforms.

## What does NOT belong here

- Specific model names or experiment scenarios — those go in
  `experiments/<name>/config.env`.
- Engine-specific launch flags — those go in the experiment's
  `start_server.sh` or `run_bench.sh`.
