AWS Parallel Computing Service now supports Slurm 25.11

AWS Parallel Computing Service (AWS PCS) now supports Slurm version 25.11, with support for a Prometheus-compatible OpenMetrics endpoint, and introduces new log types including scheduler audit logs.

This release of Slurm 25.11 introduces expedited re-queue, which can automatically reschedule jobs affected by node issues at the highest priority to help your workloads recover faster. You can enable a new OpenMetrics endpoint for real-time visibility into jobs, nodes, and scheduling using your existing monitoring tools. AWS PCS can now also send Slurm database daemon (slurmdbd) and REST API daemon (slurmrestd) logs to Amazon CloudWatch Logs, Amazon S3, or Amazon Data Firehose, helping diagnose accounting issues and debug API integrations. Scheduler audit logs, previously included in operational logs, are now delivered as a dedicated log type, providing independent control over ingestion and storage costs.

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.

These features are available in all AWS Regions where AWS PCS is available. Standard charges apply for log delivery destinations. To learn more about AWS PCS, refer to the service documentation.
