The author of the post claims that the warhead-like design "is literally the logo for this particular software framework." I can't verify this claim, but other Sandia frameworks (e.g. Sierra) use similar, equally overdesigned logos, so it's plausible.
A logo is the Sierra stylized text in the lower center.
And the two others in the slide's footer.
That Sandia might use, what was obviously intended as a diagram as a logo is a whole other thing but doesn't make it one.
As long as all representation of that thing are that big and readable one can assume they were not used as logos.
