WebComm.h: Implements the coalesced Broadcast Helper function, which is called during initialization to broadcast model state and synchronize model buffers prior to forward propagation. Reducer. H: Provide the core implementation of gradient synchronization in back propagation. It has three entry point functions: WebDistributedDataParallel (DDP) implements data parallelism at the module level which can run across multiple machines. Applications using DDP should spawn multiple processes and create a single DDP instance per process. DDP uses collective communications in the torch.distributed package to synchronize gradients and buffers.
