On August 2, 2010, We have successfully completed the computation of Pi to 5,000,000,000,000 decimal places on a single desktop computer in record time. This is 2.3 trillion digits more than the previous world record by Fabrice Bellard (December 2009). Therefore, we are declaring 5 trillion digits as the new world record. It was done using a program created by Alexander Yee and a desktop computer built by Shigeru Kondo.
A small portion of the computed digits are shown in the table below:

Whoa there don't flame
take a chile pile
:psyduck:
broke mah fuggin automerge
good christ
what good is all that pi if you can't even play crysis
Wheres the video card?
Why don't they just have a computer somewhere continually calculating more and more digits of pi instead of just going for these little one-off records every now and then?
Can it run Crysis ?
ninja'd
That's about 4.5 terabytes of data.
[QUOTE=FLAPJACKDANNY;23786163]Wheres the video card?[/QUOTE]
it's not necessary
96GB DDR3 :| holy shit
it doesnt have a a GOOD graphics card, the computer is built as a Server computer.
96 :ohdear:
[QUOTE=windwakr;23786666]Because there's no point. The most a normal person needs is the first few digits. And you only need around 40 for anything super precise:
So, the only reason people even do trillions of digits is so they can wave their e-peen around and show off their expensive, now useless(unless they want to run a server or something) computers.[/QUOTE]
Technically it's to demonstrate the creation of a more efficient algorithm to find Pi on limited hardware in the least amount of time.
90 trillion billion digits on a supercomputer that was calculating for a century is nothing compared to say, a personal computer that was able to find 1/10th the digits in a day. It's just a show of mathematical/programming prowess.
[QUOTE=ZekeTwo;23786197]Why don't they just have a computer somewhere continually calculating more and more digits of pi instead of just going for these little one-off records every now and then?[/QUOTE]
Because you have to write a more efficient algorithm otherwise it begins to take hours to work out only 100 or more so digits. Otherwise, why wouldn't they just leave it running longer to get a better record?

Oh Goddamn!
I bet :20bux: that the next record will be ten trillion digits, calculated on a laptop.

We've both seen that that's probably right, with mine and your system stability tester scores
Holy fuck, what the hell? Why would you ever want to go further than 3.14 anyway..

Go die.
You bring that OS war shit into here, when it's not even about the operating system on the computer.

you can't deny that Linux is more efficient than NT for number-crunching.
really this should have been using an application-specific operating system. BareMetal OS probably would have been better suited for this.

That server isn't even that good.
Only 2 CPUs?
Tons of webservers have at least 4 at the minimum.

96gb of RAM is nothing as well.
