The Computer Chronicles - Super Computers (1987)

I really wish Gary could appreciate now just how much love and respect we have for him for his contributions to the IT industry. He seems to bring such a warmness to these formal earlier episodes before the consumer revolution took off through the 90s.

Most people don’t use their computers or devices: they’re just content consumers. Engineers, programmers, and scientists actually use the damn things. I think if they magically had the super computing power of today back in the 60s-80s we would have had so many more breakthroughs. Mostly because the Cold War was going on and the funding was massive for all kinds of science and engineering. Today to get something done you have convince a moron CEO with an MBA to give you a tenth of what you need by dangling the promise of even more money in front of them. It should be embarrassing… the gulf between what we could do and what we actually bother to do these days.

I love the sponsorship adverts at the end, saying that their computers come with the 1200 baud modem! Wow, a whole 0.12Kb a second.. I worked out that it would take somewhere in the region of of 2 years 9 months to download a half hour high definition video. Or around 7 years for a high-definition movie. But even in 87 that seems a bit behind the times, because my first modem in the early 80s was a 300 baud modem, and then an 800 board modem, and I was using a 1200 baud modem by 85-86. By the early 90s I had a 19k2baud, and I believe that I was one of the first people that I knew to have a 56k bis standard modem by 95. After that it just went crazy, when we had our first fibre optic installed in 99 here in the UK, which allowed us to have the earliest 'broadband' (at least, that's what they call it!) with a whopping 256k!! So in the space of just a little over 10-years, it went from 1200 baud, to broadband in its earliest form at around 256k. After that it just took off, with 512, and then one megabit, etc and so on.. right up to today, where we have 250mbit from Virgin broadband, with routers here. And just recently they've written to me saying that they're going to be rolling out their first gigabit routers in the near future. No more waiting 20 minutes for a picture to form on the screen lol.

If your desktop is based on one of the latest AMD Ryzen processors, it might be way more powerful than the supercomputers in 1987. Take for example today's AMD based XBox Series X. It is just a game console but it already is capable of 12.15 Teraflops (12.15 Trillion Floating Point Operations Per Second) With today's desktop gaming computers, there are GPUs that are capable of 25 Teraflops or greater depending on the model. The supercomputer mentioned above is only capable of from 250 Megaflops (Million Floating Point Operations Per Second) with boost up to 1.7 Gigaflops (Billion Floating Point Operations Per Second). They had a plan to upgrade it to enable up to 10 Gigaflops or 10 Billion floating point operations per second. It has a memory of 250 Megabytes, while today's desktop has 8, 16, 32, Gigabytes or even greater.

Many times the price of the CPU is the fraction of the total price of a home computer. That can be avoided with super computers. Supercomputers don't have one CPU but a very large number of CPUs and each of them doesn't need its own monitor or hard disk, RAM, keyboard etc. A burden for the speed of a CPU is its heat. Most CPUs of home computers are air cooled because this is very safe, cheap and convenient. The supercomputers have more advanced ways of cooling like water cooling, liquid nitrogen cooling or in the case of quantum computers liquid helium. Super computers contrary to home computers do very specific tasks. The faster a computer is, the more restricted and specific tasks it does. Home computers are Jacks of all trades.

Did they get the power of a cray 1 by 1990 in a PC?

[@oldtwinsna8347]

No, definitely not. In 1990 the fastest x86 was the 486dx-33 which did a little under 2Mflops with its built in FPU and about 25 MIPS integer performance. With 3D graphic cards still many years away, video performance was limited to frame buffers only. The original Cray 1 could do 160 Mflops, which would have smoked anything the PC could do at then. In fact, it took until about 1995 when the Pentium Pro 200MHz was released that it could match the floating speed of the original Cray. From there on , speeds really got fast and eclipsed subsequent supercomputers just from the special vectorized functions within the FPU and MMX extensions (ironically, the same vectorized ability the Cray touted). And once 3d graphic cards came out, supercomputers of years prior became a distant memory of the past.

Isn't it wonderful to see California's San francisco before the tragic tents, poop and needle epidemic? I didn't even know my home town last fall. Sad. But, I guess I shouldn't talk about it, I might offend some delicate bleeding heart that doesn't seem to be offended by the actual problem.

They (big tech owners) love the chaos. They can hide their crimes to their fellow man within the smoke screen created by it. "Who's up for another round of Covid? I already have a vaccine made for it."

So, where're our hypersonic planes, huh? Looks like those supercomputers didn't really bring anything new on the table.

[@chukchee]

Where was the corruption?

[@Dan-gy3cu]

Some of the guys interviewed here probably retired 30+ years ago.

[@StaelTek]

30+ years ago is 1991 or further back. So that means they were retiring right after airing the episode.

Then: Wow! We went up 4 MHz! Now: wow.. we FINALLY got to 4 GHz?

[@arnaudmeert1527]

Well strictly speaking the record was 8GHz with a Pentium 4 chip about.. 10 - 15 years ago. We haven't had a processor with stock speeds above 5 Ghz. The first processor to come out with 5GHZ stock is the i7-8086K but it will only be released by end of this year.

[@Phenom98]

Yes, but the GHz war ended a long time ago in the mid 2000s. That of course doesnt mean computers aren't getting faster.

[@floydjohnson7888]

These days, it's all about multiple processor cores. The quest for more gigahertz ended when someone realized that the heat densities were on a par with lesser stars.

[@KrunchyTheClown78]

For a long time it was all about clock speed, then it became about efficiency with a lower clock speed, now it's about both, plus core count.

[@jareknowak8712]

..yes, but will it run Crysis?

WELL ITS 2023 SOOOOOO…. WHERES OUR 12 MIN CA TO NY FLIGHTS (;

Check this out....this computer can produce 1.7 billion calculations per second when pushed. Today one can go out and buy an Xbox Series X for 500 bucks that produces 3.8 billion calculations per second...per core. That is absolutely ludicrous.

My pc does what the supercomputer can do but I use it for nothing special so whats the point

An iPhone 4 has more power processing power than a Cray 2

Back in the old days we used thousands of Asians equipped with abacuses to simulate fluid dynamics. They are sadly out of a job now.

[@behrens97]

Computer Chronicles is awesome. However, not that it's the shows fault but 33 years later and there is still nothing close to a 15,000 knot Orient Express supersonic super plane. I think NASA duped us on that one and what a waste of tax payers money, jeez. It was laughable watching this. Taking a look back and watching things like this is a huge eye opener.

[@ed7590]

I'm an aerospace engineer, it's not oncommon to propose a highly PR favourable project to get funding for peripheral technologies. In this case they probably used the PR momentum to get funding for these Cray supercomputers and R&D for the CFD software.

[@Grunchy005]

Mach 20 is pretty much re-entry velocity, that necessitates a heat shield. I remember there was a lot of speculation in the 1980s about sub-orbital hops to travel quickly around the Earth. It's conceivable, but re-entry heat shields are always the limiting factor. (It's not that unreasonable an idea, it takes about 30,000 gallons of kerosene for SpaceX to reach orbit vs about 50,000 gallons to fill up a jumbo jet. The difference is that the rocket can move a few people whereas the jumbo jet transports hundreds.)

[@bb1televator]

I watched this on a tablet that probably destroys that super computer

[@Zarnubius]

33 years from now, some kid is going to trip onto this comment section on accident through the archives and laugh because he has a 900 petaflop MMI with a 40 exabyte wetdrive that destroys our 2020 Fugaku supercomputer.

[@Perplexer1]

So Cray-2 had about 2 GB of RAM 😀

[@danielcubillos1325]

10 Ghz "super computer" a today's Quad Core running at 2.4 Ghz for a mere 50 dollars could match that beast... well still impresive for the time.

[@looneyburgmusic]

Not quite... It's not just how fast the processors were/are that matters, but also HOW that speed is used, and the massive vector processing capabilities of super computers such as the famous Cray line would still be impressive today, compared to any modern computer.

[@dawsonpate7385]

@@looneyburgmusic well that's where the 250 million floating point operations per second metric comes in. Today's smartphones can easily outperform on raw power, but true it's not the power that matters . . . It's the software that drives it. But yes a smartphone in terms of raw performance would drive this to the ground. If the phone were programmed bare metal to run this software it would very easily overtake this supercomputer, but for now it's juggling a taxing os and handling tons of other processes outside of the one on the screen

[@soviet9922]

Remember paul shimler in an older episode saying that the mac was a toy and will fad away after a few months. and now he is showing off mac software xD

[@vurpo7080]

No, he said that the Mac is a good machine but he does not believe it will see success in the business/office market. Which I guess he was correct on

[@BlownMacTruck]

Why do people constantly post these types of comments as if they’re the only ones who’ve ever thought of it or amazed that technology from 30+ years ago was slower?

[@pulsar01z]

No. 10 billion flops is 10 gflops, which is 0.01 tflops. More like 1000 times if you have at least a 8 TFlops RTX and 1 Tflops top end Ryzen 9 (which is basically a high end PC by 2021 standards). a 386 had 4m flops... so 0.004 gflops. (a 1987 supercomputer was 2500 times faster than a 386)... Aurora will have 1 exaflops... which is 100000x faster than a 2021 high end gaming PC... and probably a million times faster than your average joe's laptop. What does all this mean ? 2020s supercomputers are 40 times faster than 1980s supercomputers relative to commercial pcs of their time.

[@samoryTure]

A decent Today's gaming computer is probably more powerful than the supercomputer @4:38
