python - PyTorch DataLoader shuffle - Stack Overflow
WebDec 22, 2024 · Host to GPU copies are much faster when they originate from pinned (page-locked) memory. You can set pin memory to True by passing this as an argument in DataLoader: torch.utils.data.DataLoader(dataset, batch_size, shuffle, pin_memory = True) It is always okay to set pin_memory to True for the example I explained above. WebHow FSDP works¶. In DistributedDataParallel, (DDP) training, each process/ worker owns a replica of the model and processes a batch of data, finally it uses all-reduce to sum up gradients over different workers.In DDP the model weights and optimizer states are replicated across all workers. FSDP is a type of data parallelism that shards model … how much is private school in iowa
