AI brief
AWS describes integrating the 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. The post covers async checkpointing, in-process restart, and ft_launcher in-job restart.
Why it matters: It offers a way to keep distributed training running through GPU faults without restarting the whole job.
