Abstract: One or more data loaders in a distributed computer system access input data from a storage component. A trainer in the distributed computer system transmits a training data request. The trainer and the one or more data loaders are executed on separate processors. In response to receiving, by a data loader of the one or more data loaders, the training data request, the data loader executes a data loading task to generate a training batch. The data loader transmits the training batch to the trainer. The trainer executes a training task which includes using the training batch to execute a machine learning algorithm.
