NVIDIA DSX OS：配置、认证与运维 Kubernetes GPU 集群
原标题：Configure, Certify, and Operate Kubernetes GPU Clusters with NVIDIA DSX OS
AI 摘要
NVIDIA 发布开源软件层 DSX OS，包含 AICR、NVCRE 和 NVSentinel 三个 Apache 2.0 项目，分别用于配置、认证和运维 Kubernetes GPU 集群。AICR 通过版本锁定配方建立可复现基线，NVCRE 用 AI 工作负载验证集群就绪状态，NVSentinel 监控健康并自动隔离故障节点。该方案旨在解决单块 GPU 性能下降拖慢分布式训练、且利用率指标难以发现的问题，以 goodput 衡量集群效率。

One underperforming GPU can slow an entire distributed training job. The node may pass basic health checks and show normal utilization, leaving operators to discover the problem only after the workload is running. These issues can appear at any point in a cluster’s lifecycle. A GPU cluster that passes readiness checks at handover changes as nodes are replaced, drivers are patched, and capacity is added. Without repeated validation, the original certification no longer reflects the cluster’s cond
