'Super Computers' be they one processor (none at this time) Six to ten un-hobble Play Station CPUs used to be many, and the Air Force is resurecting many), a thousand really old AMD cpus, A Cray, Which hobbles together many more AMD newer CPUs...

are all Super Computers, made of several commercially available (except possibly the Chinese one) cpus, computers, systems or glued together whizz-bangers.
NASA sent men into space with less computer power than the later 486 desk tops (which, were faster than the 'first' super computers.)

If Scientists were upset because Sony screwed up their Super Computers because Sony disabled 'Linux' in the Play Station....Your faux definition of 'commercially avaiable' and hacked together' have little meaning in the Definition of 'non-super computer'.
It has to do with how many instructions and threads are handled - - - ONLY.... and how fast they are handled.
