If individual contributors want to maintain a record of what changes/contributions they have specific copyright on, they should indicate their copyright in the commit message of the change, when they commit the change to one of the IPython repositories.

项目描述

使用 IPython 进行交互式并行计算

IPython Parallel ( ipyparallel) 是一个 Python 包和 CLI 脚本集合，用于控制 IPython 进程集群，基于 Jupyter 协议构建。

IPython Parallel 提供以下命令：

  • ipcluster - 启动/停止/列出集群
  • ipcontroller - 启动控制器
  • ipengine - 启动引擎

安装

安装 IPython 并行：

pip install ipyparallel

这将为 Jupyter Notebook 和（从 7.0 起）Jupyter Lab 3.0 安装和启用 IPython Parallel 扩展。

跑

启动集群：

ipcluster start

从 Python 中使用它：

import os
import ipyparallel as ipp

cluster = ipp.Cluster(n=4)
with cluster as rc:
    ar = rc[:].apply_async(os.getpid)
    pid_map = ar.get_dict()
