Miniature model Cray X-MP supercomputer
The miniature model supercomputers that Cray salespeople carried sometimes hit eBay, and they're getting quite pricey. This 3.75" tall scale model of the Cray X-MP, once the world's fastest computer, is on offer for $700. I wonder, if you put a Rasberry Pi in it, would the resulting machine be faster than a Cray X-MP? The X-MP offers four processors and 800 megaflops, according to Wikipedia; a Pi 4, with four cores, cracks 2 gigaflops in this benchmarking roundup. In this test, a Pi Zero (240 megaflops) outpaces a Cray 2 at calculating digits of Pi, but the consensus seems to be that the Cray would roast it at linear algebra, the sort of work supercomputers were made for.This listing is for a Cray salesman's kit model used for sales calls for potential X-MP customers. The X-MP was Cray Research's second computer, following the Cray-1. It was the world's fastest computer from 1983-1985.This Cray X-MP scale model comes in four pieces. The computer floor is made from a 12.25"x7.5"x0.25" black Lucite. The Lucite has a white "felt" fabric has squares laid out that represent 2 foot square raised computer room floor tiles. The largest part of the model is the X-MP processor. The diameter of the "C" is 5.5". This, and the other two X-MP pieces, are all 3.75" tall. The second piece that connects to the X-MP with two arms is the SSD (Solid-State Device). The third piece, which sits part from the X-MP/SSD complex, is the IOS (Input-Output Subsystem).Read the rest
