I would disagree, slightly.  I would say that a node is a single system
image. That is, it's one one image of the operating system. The physical
boundary is a good rule of thumb, but doesn't always work.

OK,  I agree here.  I've used a SiCortex 648 where it had 6 cores per node, and a bunch of nodes mounted on blades.  Each node had its own OS image running and you could ssh to it, etc.
