NVIDIA DSX OS：配置、认证与运维 Kubernetes GPU 集群
Configure, Certify, and Operate Kubernetes GPU Clusters with NVIDIA DSX OS
NVIDIA 推出 DSX OS，用于 Kubernetes GPU 集群的配置、认证与运维。单个性能不达标的 GPU 就可能拖慢整个分布式训练任务，而节点往往能通过基础健康检查、利用率显示正常，运维人员只能等工作负载跑起来后才发现问题。这类问题可能出现在集群生命周期的任何阶段，节点更换、驱动打补丁后，交接时通过就绪检查的集群也会发生变化。

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…
