The torch.distributed package provides PyTorch support and communication primitives for multiprocess parallelism across several computation nodes running on one or more machines. The class torch.nn.parallel.DistributedDataParallel () builds on this functionality to provide synchronous distributed training as a wrapper around any PyTorch model.

Distributed Data Parallel — PyTorch 1.10.0 documentation Distributed Data Parallel Warning The implementation of torch.nn.parallel.DistributedDataParallel evolves over time. This design note is written based on the state as of v1.4. torch.nn.parallel.DistributedDataParallel (DDP) transparently performs distributed data parallel training.

As of PyTorch v1.6.0, features in torch.distributed can be categorized into three main components: Distributed Data-Parallel Training (DDP) is a widely adopted single-program multiple-data training paradigm. With DDP, the model is replicated on every process, and every model replica will be fed with a different set of input data samples.

The distributed package included in PyTorch (i.e., torch.distributed) enables researchers and practitioners to easily parallelize their computations across processes and clusters of machines. To do so, it leverages message passing semantics allowing each process to communicate data to any of the other processes.

Please refer to PyTorch Distributed Overview for a brief introduction to all features related to distributed training. Note DistributedDataParallel can be used in conjunction with torch.distributed.optim.ZeroRedundancyOptimizer to reduce per-rank optimizer states memory footprint. Please refer to ZeroRedundancyOptimizer recipe for more details.

The distributed optimizer creates an instance of the local Optimizer on each of the worker nodes and holds an RRef to them. When torch.distributed.optim.DistributedOptimizer.step () is invoked, the distributed optimizer uses RPC to remotely execute all the local optimizers on the appropriate remote workers.

Probability distributions - torch.distributions The distributions package contains parameterizable probability distributions and sampling functions. This allows the construction of stochastic computation graphs and stochastic gradient estimators for optimization. This package generally follows the design of the TensorFlow Distributions package.
