Episode 6 of HPC From Scratch builds the full accounting layer: account hierarchy with sacctmgr, QOS policies with wall-time limits, and fair share scheduling with exponential decay. The result is a scheduler that adapts to actual usage and prevents any single user from dominating the queue. https://theloginnode.com/posts/hpc-from-scratch-05/ Wed, 20 May 2026 00:00:00 +0000 https://theloginnode.com/posts/hpc-from-scratch-05/ Getting Slurm running from source is more involved than installing from a package manager, but it gives you full control over version and build options. Episode 5 covers the complete setup: MUNGE for authentication, slurmctld on the controller, slurmd on compute nodes, and verifying everything works with a real batch job. https://theloginnode.com/posts/hpc101-04/ Wed, 28 Jan 2026 00:00:00 +0000 https://theloginnode.com/posts/hpc101-04/ Job failures on HPC clusters are frustrating, especially without clear feedback. This post breaks down how to use sacct, seff, and Slurm log files to figure out exactly what went wrong and how to prevent it next time. https://theloginnode.com/posts/hpc101-01/ Sat, 27 Dec 2025 00:00:00 +0000 https://theloginnode.com/posts/hpc101-01/ Every HPC user starts somewhere, and it usually involves staring at a login prompt with no idea what to do next. This post covers the three things you need on day one: SSH access, loading software with the module system, and submitting your first Slurm batch job.
