Restore LLM Inference Capacity in Seconds with Shadow Engine Recovery in NVIDIA Dynamo

NVIDIA Dynamo introduces shadow engine recovery to restore LLM inference capacity rapidly after process failures. The preview feature avoids cold restarts that require reloading weights into high bandwidth memory and recompiling kernels. Surviving workers handle displaced traffic during initialization, which can take minutes for large models. This mechanism reduces downtime for distributed inference systems using NVIDIA hardware and software stacks.
