Accelerate ND-Parallel: Master Efficient Multi-GPU Training
I still remember the first time I tried to scale a billion-parameter model across a cluster of GPUs. It was a disaster. I spent more time debugging NCCL timeout errors and synchronizing gradients than actually training the model. If you've been in the trenches of distributed deep learning, you know this pain intimately. The hardware is there, but the software glue often feels brittle. That is exactly why Accelerate ND-Parallel has caught my attention recently. It promises to solve the "multidimensional headache" of modern model training. If you are tired of juggling Data Parallelism (DP), Tensor Parallelism (TP), and Pipeline Parallelism (PP) manually, you need to pay attention. In this guide, we are going to tear down how this feature works and why it matters for your training pipeline. What is Accelerate ND-Parallel? To understand Accelerate ND-Parallel , we first need to look at the messy state of current distributed training. Traditionally, you picked a...
