From the page : "Andromeda, a 13.5 Million Core AI Supercomputer". Blown away by the number of cores (I considered myself lucky to have 2 10000+ cores GPU in my workstation) I then realized that the word "core" is singular in the sentence. Is it just a mistake or does it mean something else ? (genuine question, English is not my first language)
EDIT: Ahhh a bit below on the page it is written "13.5 million AI-optimized cores" and there it's plural. So it was probably just a mistake.
It is not a mistake, that is how you phrase it in English when the noun ("core" in this case) is being used as part of a compound adjective. The convention is to keep the noun singular.
e.g.
"He commanded a ten thousand man army." (not men)
"Andromeda, a trillion star galaxy, is 2.5 million lightyears away." (not stars)
Not a native English-speaking person, but shouldn’t it be "He commanded a ten-thousand-man army" and
"Andromeda, a trillion-star galaxy, is 2.5 million lightyears away"?
I am a native speaking English-speaking person, and although I think you are correct in that compound adjectives have historically been connected with hyphens, that seems to have fallen out-of-fashion somewhat.
To expand on the sibling comment, this is when pedantic people start talking about hyphenation. The clearer way to say this is "13.5-million-core AI supercomputer".
