/**
|
||
* 通用算法任务调度器(Route B)
|
||
* ------------------------------------------------------------
|
||
* 职责:
|
||
* 1. 维护一个带上限的并发池(默认 4 并发),避免一次性 fork 太多
|
||
* Python 子进程把宿主机打爆;
|
||
* 2. 把每个任务 fork 到独立 Node 子进程(algorithmJobRunner.ts),
|
||
* 让 HTTP/Vite 主进程不阻塞;
|
||
* 3. 子进程负责按 manifest 执行 process / mock runtime,
|
||
* 解析 stdout 进度,写 result.json,更新数据库。
|
||
*
|
||
* 主进程不直接 spawn Python,而是 fork Node runner —— 与现有
|
||
* smoothHeatmapJob / deviationHeatmapJob 的架构保持一致。
