AWS Parallel Computing Service (PCS) began supporting detailed scaling logs that record each compute node's lifecycle events such as launches, registrations, scale-downs, or launch failures with reasons. These logs enable users to diagnose scaling behavior and issues by providing granular visibility into state transitions within HPC clusters managed by PCS.
Scaling log delivery is opt-in and can be configured to send data to Amazon CloudWatch Logs, Amazon S3, or Amazon Data Firehose. AWS PCS simplifies running Slurm-based HPC workloads with managed operations and observability features, and the logging enhancement helps users better understand cluster scaling dynamics across supported AWS regions.
