Fault tolerant distributed training on Amazon EKS using NVRx
Optimizing large-scale PyTorch FSDP training on Amazon EKS with rapid fault recovery and async checkpointing.
Integrate NVIDIA Resiliency Extension (NVRx) into PyTorch FSDP training on Amazon EKS to overlap checkpoint I/O with training and recover from GPU faults in seconds. This post covers async checkpointing, in-process restart, and ft_launcher in-job restart, with H100 benchmarks at ...

NVIDIA Resiliency Extension (NVRx) effectively minimizes the massive downtime overhead typically associated with large-scale model training failures on distributed clusters. By enabling near-instantaneous recovery through in-process restarts, this solution ensures that high-value GPU compute resources remain productive despite underlying hardware instabilities.
