Useful especially when scheduler is too busy that you cannot get multiple GPUs allocated, or you need more than 4 GPUs for a single job. Requirement: Have to use PyTorch DistributedDataParallel(DDP) for this purpose.

WebbSharding It is not enough to run pipelines on different GPUs. During the training, each GPU needs to handle different samples at the same time, and this technique is called sharding. To perform sharding the dataset is divided into multiple parts or shards, and each GPU gets its own shard to process.
