AWS ParallelCluster is a fully supported and maintained open source cluster management tool that makes it easy for scientists, researchers, and IT administrators to deploy and manage High Performance Computing (HPC) clusters in the AWS cloud. HPC clusters are collections of tightly coupled compute, storage, and networking resources that enable customers to run large scale scientific and engineering workloads. 

Significant feature enhancements to this latest release of ParallelCluster include:

  • Enhanced pcluster update functionality: The pcluster update command allows customers to modify attributes of a running ParallelCluster cluster such as the instance type of compute nodes. With the latest version of ParallelCluster we have provided an improved interface so that customers can stage and inspect the changes to be applied by an update action before execution, as well as review instructions for further actions required to perform the update safely

AWS ParallelCluster is available at no additional charge, and you pay only for the AWS resources needed to run your applications. AWS ParallelCluster is released via the Python Package Index (PyPI). AWS ParallelCluster’s source code is hosted under the Amazon Web Services repository on GitHub at, where you can learn how to launch your own HPC cluster on AWS.
