To this day, whenever I hear the term "supercomputer", I can only visualize the Cray. I don't want to know what the latest supercomputer looks like, because I suspect it's just another boring bunch of rack aisles. Maybe with a snazzy color end-cap or blue LEDs on the doors.

Bring back the impractical, space-eating circular design! I don't care about space efficiency. It's supposed to look cool.

This is an area where I wouldn't mind a little splurge in design. These are supposed to be the greatest computing machines made, they should look fabulous and mysterious.

Well, a bunch of racks with green LEDs is more practical, cheap and functional, I guess.

Haha so green LEDs are cool again? I made a call back in 2004 that after blue LEDs became commonplace and white LEDs had their turn as the new hot thing, red would make a comeback. And it did. ;)

I imagine there have been multiple cycles through the spectrum since then…

Isn't that due to green being the highest energy of light for an LED available at that time? IIRC, everytime a new material was created to get the increase in band gap for a higher energy photon (i.e. blue or violet), there was a Nobel prize given out.

Tuning the band gap with a new material back then was difficult I think.

green has a lower band gap relative to blue/white, ~2V depending on chemistry, but there's something like that going on - IIRC human eyes are most sensitive to green around the ~500/550nm wavelength that green LEDs emit, so you can get good brightness out of low power.

Then consider that everybody's smartphones would make it into the TOP500 in 1993.

I'm a big fan of some of the graphics you see on the big rack farms too. Like the Jaguar art Cray used a decade or so back.
