 In this approach you use a primary node and one or more worker nodes. Within the primary node you initialize a W&B run. For each worker node, initialize a run using the run ID used by the primary node. During training each worker node logs to the same run ID as the primary node. W&B aggregates metrics from all nodes and displays them in the W&B App UI.
