Chinese supercomputer named world's fastest

November 14, 2010 The supercomputers on the Top 500 list, which is produced twice a year, are rated based on speed of
performance

China overtook the United States at the head of the world of supercomputing on Sunday when a survey ranked one of its
machines the fastest on the planet.

Tianhe-1, meaning Milky Way, achieved a computing speed of 2,570 trillion calculations per second, earning it the number
one spot in the Top 500 (www.top500.org) survey of supercomputers.

The Jaguar computer at a US government facility in Tennessee, which had held the top spot, was ranked second with a
speed of 1,750 trillion calculations per second.

These PF records will come and go quickly for the next couple of years.
GPU technology makes it possible for anyone with around 1/2 mn to
make a PF-scale machine. It only takes some impetus (such as govt
pushing some money at you for no reason to make it happen.

Just 10 y back a cheap 1 TF machine occupied a whole room. These
days a 100 TF machine can sit on your desktop.

In our days, every idiot has a computer more powerful then Cray-2. So
what? Yet 40 years ago people used to walk the Moon and build the
things like Concorde.

Rolls-Royce used to make engines that didn't explode...

Vladimir:

People _achieved_ a number of times to walk in the moon (but you'll have
fingers to spare if you count w/two hands) and only one company
engineered the Concorde, a feat which has not been replicated to become
drill exercises in any engineering curricula or perceived as low tech
that can be done at whim.

But...

It will only work for 6 months, then the BAD CAPS will kick in.
Then it will get the Won't Boot Syndrome, or just crash at random
Intervals.

Rolls-Royce also managed (pun intended) to go bankrupt in 1971 when cost
of development of 'fuel efficient' turbines development costs overran a
'mere' 100%...

I didn't realise the RnD of their cars was so costly.

Yes, and in those days we had people and corporations who were prepared
to work hard and take risks.

Actually, Concorde was a collaboration of /two/ companies (one British,
one French - as impressive a feat of linguistics and diplomacy as of
engineering).

Wonder how they managed not mixing feet, pounds and gallons with metres,
kilograms and litres

 

[barathbushan]

who would have expected that a chinese supercomputer would be the fastest

 

[bugalugs]

It's no problem - here in the rational world, technical, engineering and
scientific measurements are always done in metric. In the UK, imperial
measurements are used for rough values (such as "a pint of milk", or
"six foot tall"), but metric is used for accuracy or whenever you need
to calculate something.

I dunno three fifths of five eighths of SFA is a fairly accurate
measurement. Metricate that and you've no idea how much your talking
about.

 

[Hans-Bernhard Bröker]

I dunno three fifths of five eighths of SFA is a fairly accurate

And what kind of measure is an "SFA" supposed to be? Why would anyone
particularly need or want three eights of that?

Metricate that and you've no idea how much your talking about.

Pardon the metrically biased, but I'm having no idea what you talking
about even _before_ metricating it!

The Frogs would not build it unless they were in charge. Notice it is no
longer flying.

Maybe they did it the Canadian way: have bolts with metric heads and
imperial threads in an effort to keep everyone happy...

Yeah, but they won't go into imperial holes. BTW, isn't Whitworth an
entirely separate standard from the "standard" imperial standard? I
seem to recall that Whitworth was not used much by the time my
brother's MGA was made. Looking at Wikipedia they say the thread for
mounting cameras to tripods is a Whitworth.

Is Whitworth still used much?

Rick

Yes - at least in camera bottoms.

Otherwise, it is so coarse that it is time to follow the dinosaurs.

I'm not too fond of French inventions, but the metric system is
quite practical, especially as the Germans have put some order
into it (DIN = Das ist Norm).

Nope, there is no such animal as that last.

Thats just plain wrong.

Depends what you call much. Certainly most pom industry has sunk beneath the waves now.

 

[F Murtz]

"SFA" is an abbreviation for "sweet <bleep> all" (I hope you don't mind
the <bleep> - there may be children or Americans reading here).

Sweet fanny adams (to be respectable)
In other words, three fifths of five eighths of sweet fanny adams.

Yes. It's a pity they didn't manage to get rid of 1 day = 24 h * 60
min/h * 60 s/h (though they tried)

 

[Tauno Voipio]

Yes. It's a pity they didn't manage to get rid of 1 day = 24 h * 60

The sixty-based time and angle system is probably the
oldest mathematical heritage still in everyday use.

It comes from the 60 -based number system of old
Sumerians.

Yes. This, in turn, seems to derive from 12-based number systems. Twelve
is the number of phalanges in the four fingers of one hand (the thumb of
the same hand being used to count them). You can count five consecutive
rounds of twelve using the four fingers plus thumb of the other hand to
remember each round. Thus, 12 * 5 = 60. Of course, this is all
speculative. If we had four phalanges in each finger, instead of three,
we would be more fluent in hexadecimal
