Setting this to a larger number may reduce the degree of parallelism for multi-GPU training. + - The maximum number of nodes in the subgraph executed in bulk during training (not inference). Setting this to a larger number may reduce the degree of parallelism for multi-GPU training. Review comment: Is there any empirical result showing that using different number of max_node for forward/backward provides more speedup? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
