WebNov 19, 2024 · In this tutorial, we will learn how to use multiple GPUs using ``DataParallel``. It's very easy to use GPUs with PyTorch. You can put the model on a GPU: .. code:: python device = torch.device ("cuda:0") model.to (device) Then, you can copy all your tensors to the GPU: .. code:: python mytensor = my_tensor.to (device) WebTo calculate the global batch size of the DP + PP setup we then do: mbs*chunks*dp_degree ( 8*32*4=1024 ). Let’s go back to the diagram. With chunks=1 you end up with the naive MP, which is very inefficient. With a very large chunks value you end up with tiny micro-batch sizes which could be not every efficient either.
