WebMar 1, 2024 · LOCAL_RANK - The local (relative) rank of the process within the node. The possible values are 0 to (# of processes on the node - 1). This information is useful because many operations such as data preparation only should be performed once per node --- usually on local_rank = 0. NODE_RANK - The rank of the node for multi-node training. WebTo help you get started, we’ve selected a few NEMO examples, based on popular ways it is used in public projects.
