For the first time mathematicians were able to calculate the Pi constant with 10 trillion decimal digits.
Ten trillion would represent a 1 with 13 zeros. If you were to print that number on paper, you would need about 2.87 billion sheets, based on a standard configuration of about 3500 digits per sheet. Such a stack of paper would reach a height of 21.4 miles.
According to an unofficial announcement the calculation of the 10 trillion digits, it took 371 days and an additional 45 hours to verify on a system equipped with two Intel Xeon X5680 processors, 96 GB of memory and 24 2 TB hard drives. Only the first 5 trillion are offered for download as decimals via five separate downloads totaling 1.91 TB at this time.
The record of 10 trillion records doubles the previous record of 5 trillion digits, which was posted in August of this year.

After so many Bulldozer world records a nice one from Intel
And the point?
They could have folded for the cure.
I wonder if this scales linearly, would adding two more processors cut the time in half?
and how it compared to the gpu? would compute it too with more lesser time?
Are they hoping that when they get to something daft like 100 trillion digits is stops recurring and becomes a fixed number?
What a useless use of such a computing power. Might as well make a heater out of those Xeon machines for my dog.
Another calculation...... that's not to anyone's use..... plus the amount of electricity they wasted calculating that crap, they could have easily folded those 2 processors and got a good number on the folding list atleast helping someone calculate something more meaningful and helpful.
Why would I want to download 1.91 TB of just numbers
"waa its not helpful, you should use it for curing blahblah disease"
stfu. without scientific and mathematical advances, you wouldn't be able to 'fold' at all. this is a mathematical advancement, which will lead to more accurate scientific measurements. if we followed your logic, we'd still be creating scientific ways to determine if someone is a witch.

if they used two bulldozer fxes to count those pi numbers they would have

What a waste...

To the average person, these calculations are worthless... but to a mathematician working at NASA they are a gold mine... I guess... But I would assume that NASA would get the same number faster from their own supercomputers...
I swear a CUDA capable GPU would crunch much more then that in the same time frame.
In the end it would all still be useless to us lol.

i was just saying to my self the price of hard drives has gone thru the roof!

Imagine the size uncompressed!
chuck norris counted over 50 trillion digits of pi by counting the number of facial hair he has.
Actually it is not so much about the calculation of pi as it is about measuring the numerical and computational capabilities of the hardware. We sure want to be able to trust that the hardware is computing even more "meaningful" things correctly. Calculation of pi is a commonly used benchmark tool for measuring hardware in this regard.

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.
2 TB of Harddrive
24 2TB HDDs = 48TB.
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.
I bet every one of those mathematicians wasted even more resources on incontinence pads....Sorry, piPads
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

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