The HN crowd would probably prefer reading the many technical details at the ORNL press release: https://www.ornl.gov/news/frontier-supercomputer-debuts-worl... which I just submitted here: https://news.ycombinator.com/item?id=31573066

Also, yesterday Tom's hardware had a detailed article: https://www.tomshardware.com/news/amd-powered-frontier-super... 29 MW total, 400 kW per rack(!)

And, anyone else is like me and wants to see actual pictures or videos of the supercomputer, instead of a rendering like in venturebeat article? Well, head here, ORNL has a very short video: https://www.youtube.com/watch?v=etVzy1z_Ptg We can see among other things: that it's water-cooled (the blue and red tubing), at 0m3s we see a PCB labelled "Cray Inc Proprietary ... Sawtooth NIC Mezzanine Card"

What blows my mind is the newest NOAA super computer (that triples the speed of the last one) is a whopping 12 petaflops. It comes online this summer. It kind of shows the difference in priority spending, when nuclear labs get >1000 petaflop super computers, and the weather service (that helps with disasters that affect many Americans each year) gets a new one that is 1.2% of the speed. https://www.noaa.gov/media-rel…

DOE computers are used by a wide variety of people/teams/projects, including academics and other institutions though.

Would a faster computer improve outcomes for victims of natural disaster? How much is left undiscovered about weather? Research spending is based on the potential for discovery. As a species we have studied weather since the beginning of time. How long have we been doing nuclear research? A century? Is there even an opportunity cost here? Or is it an economy of scale? As we build more supercomputers the costs go down…

One of the more commonly discussed values is predicting where a major hurricane makes landfall. We can't reliably do that yet, but if we could, evacuation zones would be both smaller & more effective.

Seems I've heard nothing but good things about AMD for the last 10 years or so. I once had an terrible experience with AMD ~10 years ago that made me swear off them for good. Had something to do with software but I remember it taking several days of work/solutions. Willing to give them another try soon though. I never seem to even use the full power of whatever CPU I get, lol.

Lisa Su joined AMD in 2012 and in 2017 the first Zen chips were released. Good people making good decisions.

Tell me what your measure of fast is?

Does it matter? A modern CPU at 5.5ghz will outperform an 8 year old CPU overlocked to 10ghz on just about any reasonable workload even if it’s single threaded.

Do you have any data to back up your claims?

Not much point submitting a dupe with the discussion already on the front page but you can email your better links to the mods who are looking for better a better link:

Why would you run a single-threaded algorithm on a supercomputer?

Because some say they are fastest computers in the world ;-)

You don't get to call the supercar slow because your driver doesn't know how to change gears.
