Mathematicians Calculate 10 Trillion Digits of Pi With Xeons

[drwho1]

10,000,000,000,000.00

A "1" with 13 "0"'s look more like this ^
I even added a decimal "." and 2 more "00"'s

and I even save a lot of trees that would have been used on all that paper wasted.
Now just send me the check

[citation][nom]psp09[/nom]So these two processors are used 371 days plus the 45 days of data verification with a 100% of workload?? i dont think so.How much was the power consumption during the whole process, someone measured that??But beside that, nice job guys.[/citation]

Hehe sorry guys 45 hours instead days.
Anyway a lot of time.

is that the god number? 3.14 is never be a correct number after all these years no one can figure it out. if 3.14 is not a correct is just wasting time to keep measure it with more computer power. it will never end.

I hope this shows that Xeon and i7...not the same

 

[digiex]

And the point?

The point is... you can now draw a circle with a 10 trillionth accuracy.

[citation][nom]intel4eva[/nom]retardeda 2600K at 5Ghz does 1 million digits of pi (using super pi) in less than 8 seconds.8 seconds ~ 1Million digits80000 seconds ~10Billion digits80000 seconds is approximately 22 hours.This is on one modern processor overclocked to 5Ghz which is doable on air.The question is what took these morons 371 days? (longer than a year)[/citation]

Right, so firstly they got to 10 trillion, not 10 billion. By your calculations, that'd take nearly 3 years.

Secondly, Super Pi is an awfully inefficient and single threaded program. I'm betting that what these guys are using isn't.

Thirdly, I wouldn't expect this to scale linearly. When the finished file is 4TB, it's going to be a lot harder to handle than a SuperPi result using next to no memory.

Fourthly, an overclocked 2600k wouldn't be suitable. They have to be far surer about accuracy than anything other than a platform with stock speeds and ECC memory can provide.

Some people think there's a message from God buried deep within certain irrational numbers, such as within Pi's digits. For example, IIRC in Carl Sagan's book "Contact", there's a scene where some mathematics researcher finds that when you arrange the 10^12 digits of Pi in a 12 x 12 lattice, the zeros form a perfect circle. Other messages buried even deeper. The concept is similar to Arthur C. Clarke's "Sentinel" (which he later expanded into the script for "2001: A Space Odessy") - a higher intelligence places a message somewhere that requires humans to achieve a certain level of technology to reach it. In Sentinel, the message was placed in a mountain on the Moon, thus requiring space travel ability. Finding messages in Pi requires computational ability.

Not that I personally believe any of this 😛..

[citation][nom]alidan[/nom]actually, this is a complete waste.remember, pi is used to calculate how round a circle is. in reality, there is no such thing as a perfect circle, and that number would end, but this is a theoretical number. take a look at a cars pistons, as a common example, i beleive that we are more than close enough there, and in a more scientific view, they always account for a margin of error. lets say this was needed land something on mars, the margin of error that they calculate would make such a precise number pointless. this is a pointless waste of resources, and almost any application of the power would have been better.[/citation]
Any circle is perfectly round. Your misunderstanding of what number pi is just astounds me.

Calculation of pi is interesting for mathematics because it's the only constant that doesn't have repeating decimal part. All others have certain string of numbers that repeat over and over after decimal point.

so what is the 10 trillionth digit?

That just made my day, i totally LOL'd when i read that. =D

 

[gregn]

I agree that it is technically impressive when inexpensive off-the-shelf equipment can perform such calculations that were explicitly in the super computer domain - which draws far, far more power so the way I see it they are actually SAVING energy!

To the above comment calling this feat "retarded' and the people "morons", even if your 2600K scaled linearly by the next 1000X (to 10 TRILLION) which it will NOT, you would have 22 hours * 1000 = 2.5+ years. Try running SuperPi to 1 Billion digits and you'll start to see how it's not linear. Good luck!!

just prove that if you assign great minds to do trivial tasks, you would get great trivial results

pi is not the only constant that doesnt have a repeating decimal, e does not either. The significance in more accurate digits in pi isnt huge, but it does play a role in many things in physics should they choose to use it in their models.

Actually there are an infinite number of constants (aka numbers) that don't have repeating strings after the decimal point - the so-called irrational numbers. Not 'irrational' in the sense that they don't make sense, but in the sense that they cannot be expressed as the ratio (irrational) of two integers - one integer divided by another. For example, the square root of two, of three, of five, etc. Also the base of the natural logarithms - "e".

The set of rational + irrational numbers = the 'real' numbers, from minus infinity to plus infinity. And if we go planar instead of linear, we get the complex numbers which is a real number part plus an imaginary part (a real multiplied by the square root of -1, aka "i"): a +bi, where a and b are real numbers.

And before anybody says irrational or real or complex numbers are useless in ordinary day-to-day life, just remember that anytime you use a radio or TV or iPod or cellphone or whatever communications-type electronics device, they were designed in part using Fourier or Laplace transforms for their frequency response, which are calculated using complex numbers (esp. the inverse Laplace).

Just remember this - you can barely do anything today, except maybe poop in the woods, without using something having mathematics involved in its design 😛

thank god for this...the misinformation about maths in the comments section was surprising...

oh and, just to mess with you lot some more, pi^2=magnitude acceleration due to gravity on the earth's surface (g).

If someone memorizes all 10 trillion digits, and then recites them at 3 digits per second, it would take them about 105,699.3 years to recite them all.

 

[Guest]

who's retarded ?
8 seconds ~ 1Million digits
80000 seconds ~10Billion digits
80000 seconds is approximately 22 hours.

yeah but they've done more than 10 bilion, it's 10 trillion
2.87 billion sheets X 3500 digits per sheets =10 trillion
so it's 22 hours X 1000 = 916 days for your 5ghz machine

also, superpi is a reference as a fiable/CPU intensive benchmark. it's not the fastest Pi calculation soft.

 

[Guest]

My iPhone 6 will do it faster, it's optimised for Pi calculation

 

[Guest]

Do your math. According to what you said, if it takes 8 seconds to calculate a million digits, then it takes 8000 seconds to calculate a billion, and 8 million seconds to calculate a trillion, so it's 80 million seconds to calculate the 10 Trillion digits.
80.000.000 seconds = 925 days

In fact i does make use of it the pop will need a space to be deposited a volume to fill,a force to get expelled(lol),etc,etc....

If they sell those 2TB drives on ebay now, they might recoup a good portion of their expenses, considering current flood prices.
