hwloc / lstopo : utility to make pretty diagrams of CPU and memory organization


I just spent 15 minutes trying to remember the name of this handy utility named `lstopo`, part of the `hwloc` package, for making pretty pictures of your systems CPU/cache/memory organization. It’s part of the elx.x core package set but it’s very difficult to find via `yum search` as none of the keys word: memory, numa, or cpu will match this package.

The man page lists extension options but you can generate pretty pictures with simply `lstopo `. Eg.

lstopo `hostname -s`.png
lstopo `hostname -s`.ps
