IPython Parallel (ipyparallel) is a Python package and collection of CLI scripts for controlling clusters of IPython processes, built on the Jupyter protocol.

IPython Parallel provides the following commands:

• ipcluster - start/stop/list clusters
• ipcontroller - start a controller
• ipengine - start an engine

Install IPython Parallel:

pip install ipyparallel

This will install and enable the IPython Parallel extensions for Jupyter Notebook and (as of 7.0) Jupyter Lab 3.0.

Start a cluster:

ipcluster start

Use it from Python:

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()
