Installing the AWS ParallelCluster command line interface (CLI)

AWS ParallelCluster is distributed as a Python package and is installed using the Python pip package manager. For instructions on how to install Python packages, see Installing packages in the Python Packaging User Guide.

Ways to install AWS ParallelCluster:

• Install AWS ParallelCluster in a virtual environment (recommended)

• Installing AWS ParallelCluster in a non-virtual environment using pip

• Install AWS ParallelCluster as a standalone application

You can find the version number of the most recent CLI on the releases page on GitHub. In this guide, the command examples assume that you have installed a version of Python that is later than version 3.6. The pip command examples use the pip3 version.

Manage both AWS ParallelCluster 2 and AWS ParallelCluster 3

For customers who use both AWS ParallelCluster 2 and AWS ParallelCluster 3 and want to manage the CLIs for both packages, we recommend that you install AWS ParallelCluster 2 and AWS ParallelCluster 3 in different virtual environments. This ensures that you can continue using each version of AWS ParallelCluster and any associated cluster resources.
