Episode 2 of HPC From Scratch covers the hardware upgrades made to the cluster nodes and explains how iGPU shared memory quietly reduces available system memory on compute nodes, with no error message to warn you. https://theloginnode.com/posts/hpc-from-scratch-01/ Fri, 13 Mar 2026 00:00:00 +0000 https://theloginnode.com/posts/hpc-from-scratch-01/ University clusters have waitlists and cloud HPC gets expensive fast. This series documents building a real 6-node HPC cluster from consumer hardware for $1,264. Episode 1 covers hardware selection, how to assign node roles, and the decisions that actually matter before you buy anything.
