Core
Slurm for AI ClustersSlurm is the scheduler most large training clusters still run, because it was built for exactly this shape of work: long jobs that need many nodes at once, launched with one command, placed with knowledge of the network. A candidate for a training-infrastructure role is expected to read an sbatch script, know how GPUs are requested and enforced, and explain why a job is stuck in the queue. This page covers the model, the commands that matter, the GPU-specific configuration, and the failure modes a platform engineer meets.🗂️ Scheduling & OrchestrationSign in

Training Cluster Design at 10k GPUsDesign a cluster for training frontier models is the prompt that tests whether a candidate can hold hardware, network, storage, scheduling and reliability in one head at once. The answer is a bill of materials with a reason for every line: how many GPUs and why, how they are grouped into pods, how the fabric connects the pods and what it costs a collective to cross one, how much storage bandwidth the checkpoints and the data loader need, how power and cooling bound the whole thing, and how the failure statistics set the spare pool and the checkpoint cadence. This page derives each line for a 10,240-GPU cluster.📐 AI Systems Design🔒 Premium
