TL;DR
The paper addresses the challenge of scaling deep learning workloads beyond single machines by presenting NVIDIA DeepOps on a Slurm-managed GPU cluster. It offers an end-to-end guide covering cluster architecture (compute nodes, GPUs, networking, storage), DeepOps installation, and Slurm-based job submission, with emphasis on reproducible environments via containers. It surveys parallelism and optimization techniques (data, tensor, and pipeline parallelism; FSDP and ZeRO) and highlights frameworks like Accelerate, DeepSpeed, and FairScale for large-scale training. The guidance is designed to enable practitioners to build, operate, and optimize a scalable GPU cluster for rapid DL experimentation and production workloads, improving training speed, model capacity, and collaboration at scale.
