WebMar 29, 2024 · When validating using a accelerator that splits data from each batch across GPUs, sometimes you might need to aggregate them on the master GPU for … WebAug 19, 2024 · Instead of communicating loss, DDP communicates gradients. So the loss is local to every process, but after the backward pass, the gradient is globally averaged, so that all processes will see the same gradient. This is brief explanation, and this is a full paper describing the algorithm.
WebApr 30, 2024 · IIUC, if this is trained without DDP (assume there are large enough GPU memory), then both feats and stddev are calculated based on all inputs. When trained with DDP, feats are now only derived from local inputs, and you would like to have stddev to be based on global inputs. WebAug 4, 2024 · DDP performs model training across multiple GPUs, in a transparent fashion. You can have multiple GPUs on a single machine, or multiple machines separately. DDP …
