NVIDIA open-sources NVCRE, a Kubernetes controller to validate GPU cluster readiness
NVIDIA Cluster Readiness Engine (NVCRE) is an open-source Kubernetes controller that runs real distributed workloads across topology-aware node groups to validate GPU cluster readiness before production AI jobs start. It exposes Certification/Workflow/Job CRDs, adaptive fault isolation to pinpoint failing nodes, a WorkloadRun API for multi-node GPU setup, integrates with NVIDIA AI Cluster Runtime and NVSentinel (part of NVIDIA DSX OS), and is installable via nvcrectl; contributors can extend tests and workload adapters on GitHub.
