Overview

Design, operate, and troubleshoot Slurm based GPU clusters that actually keep your AI training jobs running. Training modern deep learning and LLM workloads on shared GPU clusters is hard. Jobs hang, NCCL stalls, priorities feel random, and expensive GPUs sit idle while users fight the queue. Slurm for AI and Deep Learning: GPU Cluster Management and Distributed Training gives engineers, MLOps teams, and administrators a practical playbook for building a Slurm platform that is fair, observable, and reliable for PyTorch, TensorFlow, and multi node LLM training. Understand core Slurm concepts for AI work, including nodes, partitions, jobs, steps, tasks, GRES, TRES, and cons_tres. Design GPU node profiles that balance CPUs, memory, local NVMe scratch, and network for single, multi GPU, and multi node workloads. Configure slurm.conf, gres.conf, and SelectTypeParameters for correct GPU accounting and safe sharing. Apply cgroups, device cgroups, CUDA_VISIBLE_DEVICES, and MinTRESPerJob to enforce isolation and block CPU only jobs from GPU queues. Build realistic queue policies with multifactor priority, QoS tiers, fairshare, and backfill so interactive, batch, and preemptible jobs coexist. Run AI friendly patterns with sbatch and srun, job arrays for sweeps, and dependency chains for train evaluate package deploy pipelines. Use containers on Slurm with Apptainer, Pyxis Enroot, and native OCI, including GPU passthrough, driver compatibility, and secure writable layers. Align topology and placement using NUMA, PCIe, NVLink, and fabric awareness, plus binding of CPUs, GPUs, and NICs for multi node training. Launch robust distributed PyTorch with srun and torchrun, wire ranks and world size from Slurm vars, and apply DDP and FSDP recipes without hangs. Configure TensorFlow MultiWorkerMirroredStrategy with TF_CONFIG generated safely from SLURM_NODELIST and debug common gRPC and DNS failures. Orchestrate multi node LLM runs with Accelerate and DeepSpeed, including ZeRO stages, offload options, hostfile rules, and checkpoint sharding for safe resume. Tune NCCL transports and environment variables, run nccl tests on Slurm, and follow a clear decision tree for diagnosing communication stalls. Work with MIG, fractional GPUs, CUDA MPS, and packing rules such as cpus per gpu and mem per gpu without breaking isolation. Operate in production with accounting, TRESBillingWeights, sacctmgr limits, sacct and sreport based usage reviews, DCGM exporter metrics, pam_slurm_adopt hygiene, and slurmrestd automation. This is a code heavy guide with real Slurm configs, shell scripts, and training launch patterns you can adapt directly to your own clusters. Grab your copy today and turn your GPU cluster into a dependable platform for serious AI training.
