AWS Parallel Computing Service supports slurmdbd and cgroups settings

AWS Parallel Computing Service (AWS PCS) now supports additional Slurm configuration settings for slurmdbd and cgroups, enabling you to fine-tune accounting behavior and resource isolation directly through the AWS PCS console, CLI, or SDK. This feature helps you implement production-ready HPC environments with enhanced privacy controls, flexible data retention policies, and improved resource management.

Using slurmdbd settings, you can configure how Slurm accounting operates on your cluster—including privacy controls, data retention policies, and workload tracking capabilities. With cgroups support, you can prevent resource oversubscription by binding CPU cores, enforce memory limits to maintain node stability, and control device access to ensure workloads run within defined boundaries.

AWS PCS is a managed service that simplifies running and scaling HPC workloads on AWS using Slurm. You can build complete, elastic environments that integrate compute, storage, networking, and visualization tools, while the service handles cluster operations with managed updates and built-in observability features.

This feature is available in all AWS Regions where AWS PCS is available. You can configure these settings when creating a new cluster or by modifying an existing cluster. To learn more, see the AWS PCS User Guide.
