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...

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%...

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.

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 :-P

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.

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

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


Re: Chinese supercomputer named world's fastest

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

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

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

Have seen that sort of thing in Australia too.  The format of
expressing the dimensions are often (say) 3/8" x 20mm

bolts sold in this format are common, especially in those little
blister packs at hardware stores.

That's because the diameter and thread form  are an old
imperial"standard", Whitworth, whereas the length is in the country
accepted measurment standard.

If you buy metric bolts both the lengh and diameter will be metric.

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?

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).

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)

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.
