AWS PCS Gets Better Debugging with Scaling Logs
AWS Parallel Computing Service now lets you track exactly what's happening when your HPC clusters scale up or down—each compute node transition gets logged so you can troubleshoot capacity issues and launch failures like a pro. You can send these scaling logs to CloudWatch Logs, S3, or Data Firehose, giving you full visibility into your cluster's behavior across all AWS Regions where PCS is available.
