AWS Parallel Computing Service now supports dynamic cluster updates

AWS Parallel Computing Service (AWS PCS) now enables you to modify and update key Slurm workload manager settings without rebuilding your cluster. You can now adjust essential parameters including accounting configurations and workload management settings on existing clusters, where previously these details were fixed at creation time.

This new flexibility helps you adapt your high performance computing (HPC) environment to changing requirements without disrupting operations. You can make modifications through the AWS Management Console, AWS Command Line Interface (AWS CLI), or AWS SDK.

AWS PCS is a managed service that makes it easier for you to run and scale your high performance computing (HPC) workloads and build scientific and engineering models on AWS using Slurm. You can use AWS PCS to build complete, elastic environments that integrate compute, storage, networking, and visualization tools. AWS PCS simplifies cluster operations with managed updates and built-in observability features, helping to remove the burden of maintenance. You can work in a familiar environment, focusing on your research and innovation instead of worrying about infrastructure.

Cluster configuration modifications are available in all AWS Regions where AWS PCS is offered. To learn more, see the Modifying a cluster section in the AWS PCS User Guide.
