• `kernels/`（含 `kernel_config.py`、`orchestration/`、`aic/`、`aiv/`）
• `golden.py`
• `README.md`（重写为 multi_bgemm 说明） | + +**需要改动的仅**： + +- **`kernels/kernel_config.py`** + - 在 `RUNTIME_CONFIG` 中增加 `n_devices`，默认 `2`（或 `4`，由你定）；其余（ORCHESTRATION、KERNELS）与 bgemm 保持一致。 +- **`README.md`** + - 说明本 case 为「多卡独立跑 bgemm」，支持 2/4 卡；示例命令用 `--n-devices 2` 或 `--n-devices 4`。 + +### 3.2 命令行与 code_runner 入参 + +| 位置 | 修改内容 | +|------|----------| +| **run_example.py** | 新增可选参数 `--n-devices`（类型 `int`，默认 `None`）。解析后传入 `create_code_runner(..., n_devices=args.n_devices)`。 | +| **code_runner.create_code_runner** | 增加形参 `n_devices=None`，并传给 `CodeRunner`。 | +| **CodeRunner.__init__** | 增加 `n_devices` 参数。逻辑：若调用方传入 `n_devices is not None`，则用传入值；否则从 `kernel_config.RUNTIME_CONFIG.get("n_devices", 1)` 读取，默认 `1`。这样既支持「按 case 默认多卡」，也支持「命令行覆盖」。 | + +### 3.3 code_runner.run() 中「多卡分支」 + +- **触发条件**：在 `run()` 开头（在 `comm_gather` 分支之后、正常单卡 build 之前）判断：若 `self.n_devices > 1`，则走「多卡独立跑」分支，直接 return，不再走下面单卡 build/launch。 +- **多卡分支逻辑**： + 1. 解析当前脚本所在目录，得到 `run_example.py` 的路径（与 code_runner 同目录：`Path(__file__).resolve().parent / "run_example.py"`）。 + 2. 对 `device_id in range(self.n_devices)` 依次（或并行，见下）执行子进程： + - 命令：`[sys.executable, str(run_example.py), "-k", str(self.kernels_dir), "-g", str(self.golden_path), "-d", str(device_id), "-p", self.platform]` + - 可选：把当前 `--all` / `--case` / `--log-level` 等与单次 run 相关的参数一并传入，保证与单卡行为一致。 + 3. 等待所有子进程结束；若任一子进程 `returncode != 0`，则抛出异常或置失败，并带上设备 id 信息；若全部为 0，则视为通过。 +- **并行 vs 串行**：为简单起见先做成**串行**（按 device 0,1,... 顺序跑），避免多进程同时 build 争抢；若你希望 2/4 卡并行跑，可再改为 `concurrent.futures.ProcessPoolExecutor` 或 `multiprocessing.Pool`，但需注意编译/资源竞争，建议首版串行。 +- **Build 次数**：每个子进程都会完整跑一遍 run_example（含 build runtime、编 orchestration、编 kernel），因此会 build N 次；实现简单，首版接受该冗余，后续若有需要可再做「只跑不编」的优化。 + +### 3.4 不需要改动的部分 + +- **Runtime / bindings / 单卡 launch**：不变。 +- **单卡 case（如 bgemm）**：不加 `n_devices` 时行为与现在完全一致（`n_devices` 默认 1，不进入多卡分支）。 +- **comm_gather**：不受影响，仍走 `_run_comm_gather()`。 + +--- + +## 四、文件与配置清单（实施顺序） + +| 步骤 | 操作 | +|------|------| +| 1 | 新建目录 `examples/host_build_graph/multi_bgemm/`。 | +| 2 | 从 `bgemm` 拷贝 `golden.py`、`kernels/`（整个目录：kernel_config.py、orchestration/、aic/、aiv/）到 `multi_bgemm/`。 | +| 3 | 修改 `multi_bgemm/kernels/kernel_config.py`：增加 `RUNTIME_CONFIG = { "runtime": "host_build_graph", "n_devices": 2 }`（或 4）；若 bgemm 当前无 `RUNTIME_CONFIG`，则仅在 multi_bgemm 中显式写出，保持与 bgemm 相同的 ORCHESTRATION、KERNELS。 | +| 4 | 编写 `multi_bgemm/README.md`：说明本 case 为多卡独立跑计算（与 bgemm 同逻辑），示例命令 `--n-devices 2` / `--n-devices 4`，无卡间同步与通信。 | +| 5 | **run_example.py**：增加 `--n-devices` 参数，并传入 `create_code_runner(..., n_devices=args.n_devices)`。 | +| 6 | **code_runner.py**：`create_code_runner` 增加 `n_devices` 参数；`CodeRunner.__init__` 中读取并保存 `self.n_devices`（来自参数或 `RUNTIME_CONFIG`，默认 1）。 | +| 7 | **code_runner.run()**：在 `comm_gather` 分支之后、单卡 build 之前，若 `self.n_devices > 1`，则执行「多卡子进程」逻辑（循环或并行启动 N 个 `run_example.py -d 0..N-1`），全部成功则 return，否则抛错。 | + +--- + +## 五、运行示例（计划通过后） + +```bash +# 2 张卡独立跑 multi_bgemm（每卡跑同一套 bgemm 计算） +python examples/scripts/run_example.py \ + -k examples/host_build_graph/multi_bgemm/kernels \ + -g examples/host_build_graph/multi_bgemm/golden.py \ + --n-devices 2

--n-devices 4 +``` + +每张卡使用与 bgemm 相同的输入（各自 `generate_inputs` 一份，或子进程内各自生成，因随机数可能不同；若需完全一致可后续改为主进程生成写文件再传入，首版可保持各进程独立 `generate_inputs`，golden 仍按同一规则校验）。 + +--- + +## 六、小结 + +- **新 case**：`multi_bgemm`，与 bgemm 同编排、同 kernel、同 golden，仅配置多卡数。 +- **入口**：`run_example.py` 增加 `--n-devices`；code_runner 支持 `n_devices` 从配置或命令行传入。 +- **执行**：`n_devices > 1` 时用子进程对每张卡跑一次「单卡 run_example」流程，无卡间同步与通信，全部成功即通过。 + +确认该计划 OK 后，再按上述步骤改代码。 diff --git a/examples/host_build_graph/multi_bgemm/README.md b/examples/host_build_graph/multi_bgemm/README.md new file mode 100644 index
