WebMultiprocessing Library that launches and manages n copies of worker subprocesses either specified by a function or a binary. For functions, it uses torch.multiprocessing (and therefore python multiprocessing) to spawn/fork worker processes. For binaries it uses python subprocessing.Popen to create worker processes.

WebLocal rank refers to the relative rank of the smdistributed.dataparallel process within the node the current process is running on. For example, if a node contains 8 GPUs, it has 8 smdistributed.dataparallel processes. Each process has a local_rank ranging from 0 to 7. Inputs: None Returns: Web输出： 也就是说如果声明“--use_env”那么 pytorch就会把当前进程的在本机上的rank放到环境变量中，而不会放在args.local_rank中 。 同时上面的输出大家可能也也注意到了，官方现在已经建议废弃使用torch.distributed.launch，转而使用torchrun，而这个torchrun已经把“--use_env”这个参数废弃了， 转而强制要求用户从环境变量LOACL_RANK里获取当前进程 …
Web在 PyTorch 的分布式训练中，当使用基于 TCP 或 MPI 的后端时，要求在每个节点上都运行一个进程，每个进程需要有一个 local rank 来进行区分。 当使用 NCCL 后端时，不需要在 …
WebLOCAL_RANK - The local (relative) rank of the process within the node. The possible values are 0 to (# of processes on the node - 1). This information is useful because many operations such as data preparation only should be performed once per node --- usually on local_rank = 0.
