I remember there was an application that showed, in the console, or in a simple picture, the memory architecture of the system: what caches were shared by which processors, etc. but I can't remember that command. Does any of you remember off the top of your head?

hwloc, that was it. Sorry. Maybe it helps someone else. – Dervin Thunk Feb 4 '12 at 20:12
You should post it as an answer and then accept it when you can :) Good job finding the answer to your question! – n0pe Feb 4 '12 at 21:18

As per 2 requests, I will answer my question explicitly, but I will not mark it as accepted. Sounds weird to me.

The answer I was looking for is hwloc-info, or, alternatively lstopo -v --whole-system <optional-output-file>, the <optional-output-file> may be any of the major image formats ps, jpg, etc,
