A Distributed Data Parallel (DDP) application can be executed onmultiple nodes where each node can consist of multiple GPUdevices. Each node in turn can run multiple copies of the DDPapplication, each of which processes its models on multiple GPUs. Let N be the number of nodes on which the … See more In this tutorial we will demonstrate how to structure a distributedmodel training application so it can be launched conveniently onmultiple nodes, each with multiple … See more We assume you are familiar with PyTorch, the primitives it provides for writing distributed applications as well as training distributed models. The example … See more Independent of how a DDP application is launched, each process needs amechanism to know its global and local ranks. Once this is known, allprocesses create … See more As the author of a distributed data parallel application, your code needs to be aware of two types of resources: compute nodes and the GPUs within each node.

WebMar 2, 2024 · I was using torchrun and ddp in PyTorch 1.10, but torchrun doesn’t work w PyTorch 1.7 so I had to stop using torchrun and use torch.distributed.launch instead. Now it works smoothly and no sigsegv errors.

The series starts with a simple non-distributed training job, and ends with deploying a training job across several machines in a cluster. Along the way, you will also learn about torchrun for fault-tolerant distributed training.
