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:

  • Support for multiple instance types in Slurm: Users can now create multiple job submission queues inside of ParallelCluster and specify multiple instance types within each queue. On job submission, users can specify the instance types they would like to use for their job as well as the queue to which they would like to submit it, simplifying multi-stage workflows and the ability to run multiple workloads with distinct needs from a single cluster.
  • Support for DCV on Graviton2 instances: In this release, support for NICE DCV has been extended to AWS Graviton2 instances. This provides more platform choice flexibility for workloads requiring remote visualization.
  • Slurm power management plugin: We have rearchitected our integration with Slurm to use the Slurm power management plugin. This integration improves cluster stability and precision in scaling compute resources to match individual jobs’ requirements.

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