Amazon SageMaker HyperPod now supports on-demand deep health checks for Amazon EKS and Slurm-orchestrated clusters, enabling you to proactively verify GPU accelerator health on running instances at any time. HyperPod Slurm-orchestrated clusters now also support deep health checks during node provisioning, at the time of cluster creation. This capability addresses a critical challenge where even a single unhealthy node can waste hours of compute time and delay critical workloads. With on-demand deep health checks, you can target entire instance groups or specific instances to run comprehensive hardware stress tests and connectivity tests before committing compute resources to a job. Progress and results are visible at both the instance group and instance level through the SageMaker console and APIs, providing complete visibility into GPU health, network connectivity, and multi-node communication performance. Instances undergoing checks are automatically isolated from workload scheduling and returned to service upon passing. When paired with HyperPod's automatic node recovery capability, instances that fail are automatically rebooted or replaced, ensuring cluster health. This capability is available in all regions where Amazon SageMaker HyperPod is available. To learn more about on-demand health checks, see the documentation .
