WebbIn 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. Webb11 apr. 2024 · Horizontal sharding, otherwise known as range partitioning, is a technique which divides the data into rows based on a determined key or range of values. For example, a table of customers can be ... Sharding is a method for distributing a single dataset across multiple databases, which can then be stored on multiple machines. This allows for larger datasets to be split into smaller chunks and stored in multiple data nodes, increasing the total storage capacity of the system.
