- Use DistributedDataParallel (DDP) over DataParallel for multi-GPU
- Initialize process group: dist.init_process_group(backend='nccl')
- Use DistributedSampler for data sharding
- Synchronize batch norm: nn.SyncBatchNorm.convert_sync_batchnorm()
- Only save checkpoint on rank 0
- Scale learning rate linearly with world size
- Use gradient accumulation for effectively larger batch sizes
