NVIDIA 如何用自动化工作负载恢复保障分布式训练持续运行
Keep Distributed Training Running with Automated Workload Recovery
NVIDIA 介绍自动化工作负载恢复机制，用于应对分布式 AI 训练中的硬件与软件故障。训练 rank 停滞可能触发 NCCL 超时，GPU 节点可能不再响应调度器，慢节点则会拖慢整个任务。该机制旨在让这些中断可被快速可靠地处理，维持训练进度。

As distributed AI training scales, failures across hardware and software dependencies increasingly disrupt training progress, making fast, reliable recovery essential. A stalled training rank can trigger an NVIDIA Collective Communications Library (NCCL) timeout, a GPU node can stop responding to the scheduler, or a straggler can slow the entire job. Each disruption is manageable on its own…
