Introduction

I wanted to understand how LSF actually works, not just at a surface “submit job, job runs” level, but the real mechanics. Most places that use LSF don’t document it well, and when they do, it’s written assuming you already run a production cluster.

So I decided to build a small LSF Community Edition cluster at home and treat it like an EDA-style environment: master node, execution nodes, login-style submission, interactive jobs, X11, the whole thing.
