Ed G's fuzzy recollections (corrected by Shmuel)
IBM a few years ago introduced a 3838 (?) for number crunching.
IIRC
it went down in flames.
The vector facility of the 3090 replaced it.
There did not seem to be a market for such an animal.
Then why did IBM bother with the VF?
Never heard of it so I guess it, that doesn't mean it never existed
just an extremely small audience. I don't recall ever hearing
anything about VF . I would expect if it were popular that there
would be a current model, no?

The vector feature was available on some models of the 3090. It was a
SIMD (Single Instruction applied to Multiple Data operands) vector
engine and IIRC you could add VF engines but each one had to replace a
general purpose engine. IBM offered them because customers wanted
them.
The financial community bought a number of them and for a while in the
mid/late 80's the 3090/600s were in the top ten or so of super
computers. I guess it just didn't intrude on your world Ed.

I guess not. SOme people seemed to live in a world of knowing all,
pity them.
