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 AWS ParallelCluster 2.11 include:

  • Support for Ubuntu 20.04 Operating System: Customers can now choose Ubuntu 20.04 as their base operating system of choice to run their clusters for both x86 and Arm architectures. As with other operating systems supported by AWS ParallelCluster, you can choose your operating system using the base_os configuration option, and can also choose to create and use your own custom AMI built on top of Ubuntu 20.04. Ubuntu 20.04 support also includes compatibility with all of AWS ParallelCluster’s supported schedulers and NICE DCV for remote visualization.
  • FSx for Lustre in isolated subnets: Customers can now set up and mount an Amazon FSx for Lustre file system in AWS ParallelCluster without requiring public internet access. This gives customers an additional option for how they can help keep their HPC environments secure and isolated inside of AWS.


AWS ParallelCluster is available at no additional cost, and you pay only for the AWS resources needed to run your applications. Learn how to launch an HPC cluster using AWS ParallelCluster here.
