A concrete application of multi-GPU training with data augmentation involves training a standard convolutional architecture, such as a ResNet-18 model, on the CIFAR-10 dataset using multiple GPUs. In this setup, random left-right flipping is applied to the training dataset to improve generalization. The process is orchestrated by an integrated training function that leverages the Adam optimization algorithm and distributes the minibatches across all available hardware, demonstrating how high-level abstractions seamlessly handle the complexities of distributed computation and on-the-fly image transformations.

To combine stochastic image augmentation with distributed deep learning, a unified training function can be implemented to orchestrate the entire pipeline. A function like train_with_data_aug accepts specific augmentation transformation sequences for both the training and testing datasets. It utilizes data loaders to apply these random transformations dynamically and construct minibatches. The function then configures an optimization algorithm, such as Adam, and passes the neural network, data iterators, loss function, and optimizer to a concise multi-GPU training loop. This approach seamlessly integrates complex data preprocessing with high-performance distributed training across all available hardware.
