Is there any software apart from benchmarks that will make it feel that fast. All softwares that I use feel more advanced version of things that I ran on my 386. GUI, IDE, compiler, office... I understand that the exercise may still be theoretical as any sw used by Met now will be designed for million time fast computers. But there should exist some software that would have required Cray to run then.

A lot of the stuff that took hours back then can now be done in sub-seconds. Think about mechanical engineering: Back then they might have simulated how cars deform in a crash. Now we can perform similar simulations in real-time for fun in our video games. Afaik it's hardly ever done because no one actually needs physically accurate models in games, but it could be done. Same goes for rendering back then they rendere…

BeamNG is basically that.

One of the early customers was the European Centre for Medium-Range Weather Forecasts, so, wild guess, they probably used it for medium-range weather forecasts.

I thought the ECMWF models were (and always have been) global?

When I see comparisons like this, the first thought I have is not the benchmarks, but rather what the most “heroic” real-world calculation of the day would have been on something like the Cray-1, and how to replicate those calculations today on something like a RPi. Weather/climate models? Rad-hydro? The fidelity would almost certainly be super low compared to modern FEA software, but it would be a fun exercise to tr…

A Cray-1 could execute an infinite loop in 7.5 seconds!

In a similar way how Chuck Norris counted to infinity.. twice?
