Zero-restart fault tolerance for distributed AI training
clockwork.io/workload-failover
TorchPass keeps distributed AI training running through link flaps, GPU faults and node failures by migrating work off failing GPUs live instead of restarting from a checkpoint. It is software-only and works with TorchTitan, Megatron-LM, DeepSpeed, Slurm and Kubernetes. TorchPass Snapshots, launched October 2026, captures the state of a running multi-node job without training-code changes.
