README
# Interactive Parallel Computing with IPython
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
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.
## Run
Start a cluster:
ipcluster start
Use it from Python:
```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()
```
