The RPi, unlike the Cray-1, does not offer ample sitting space.
But for the price of the Cray, even without adjusting for inflation, you could buy a useful number of chairs. And just think of the electricity cost savings!

#23"In 1978, the Cray 1 supercomputer cost $7 Million, weighed 10,500 pounds and had a 115 kilowatt power supply. It was, by far, the fastest computer in the world. The Raspberry Pi costs around $70 (CPU board, case, power supply, SD card), weighs a few ounces, uses a 5 watt power supply and is more than 4.5 times faster than the Cray 1" edit: thank you for the Christmas present, yc algorithm.

#24For a second there I thought there was a new sbc called cray. Well played

#25I'd just bought the latest and most expensive Intel x86 CPU in 2013 and built myself a new rig. My wife walked into the office, "You're not working, I can tell that, but I'm not sure what you're doing?" she said looking at the graphs on my screen. "I'm calculating to see when my PC would have been the fastest on Earth. It looks like in 1992 it would be able to out-compute the latest Dept of Defense $90m supercomputer…
The other fun thing is to find out the most recent year your phone would have made the bottom of the top 500 list.

I’m more impressed that the cray was that fast such a long time ago tbh
That all began with the CDC 6600.

#28When 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 try.

One of my favorite machines from Top500 is SystemX.
https://www.top500.org/system/173736/
When it was commissioned in 2004, this array of 1100x Apple PowerPC 970 systems was the 7th most powerful computer on the list.
It's Linpack Performance was 12,250.00 GFlop/s.
Re: Cray-1 vs Raspberry Pi
#30There's a line in the Jurassic Park book where a character is made suspicious by an offhand assertion (by Nedry) that he is using a multi XMP system . Rpi4s are nice, in a sense, because you can only rarely honestly claim that the speed of the system is holding you back. Most times, presumably, it's the efficiency of the operations you are telling it to execute.

As someone who uses them for a variety of purposes, I gotta note that they have pretty huge limitations. Like, the moment graphics enter the picture (no pun intended) you’re moving an order of magnitude slower than most desktops or laptops. Not to mention that support for hardware video encode/decode (which, especially decode, we generally take for granted) aren’t always available depending on the library or tool you’re working with.
Like yes, you can totally run a serviceable web server on a Pi and serve a blog or a small web app, but let’s not get carried away here.
