A comparitively humble desktop computer has successfully calculated pi to 2.7 trillion digits, 123 billion more than the previous record set by a supercomputer in August 2009. Since 1995, records for pi have been set by supercomputers, but Fabrice Bellard claims his method is 20 times more efficient.

Gizmag reports that using a Core i7 running at 2.93GHz, with 6GB RAM and a 7.5TB of hard disk space, it took 131 days and over a terabyte of disk storage for Febrice Bellard to complete and check the record of 2,699,999,990,000 digits.

So how long is that number? According to the BBC, if you were to recite one number every second, it would you over 49,000 years to reach the end.

Although the previous record, set in August 2009 by Daisuke Takahashi at the University of Tsukuba in Japan, took just 29 hours to complete, it was done using a supercomputer 2,000 times faster and considerably more expensive than the desktop computer used by Bellard.

Calculating the digits of pi is about more than just setting records however. Ivars Peterson, director of publications at the Mathematical Association of America, told the BBC, "People have used it as a vehicle for testing algorithms and for testing computers; pi has a precise sequence of digits, it's exactly that, and if your computer isn't operating flawlessly some of those digits will be wrong.

"It's more than just for the fun of it - pi is a way of testing a method and then the method can be used for other purposes."

+metal_dragen2,699,999,990,000 digits - that's doesn't exactly fit in a 500kb Word doc if you take my meaning.

Actually, assuming that he used 1 byte to store each digit, it should have taken 2.46TB of disk space.

srsly this is ridiculous :S

You mean 2,699,999,990,000 / (60 * 60 * 24 * 365.25) = 85,557.84

However, he calculated Pi to 2.7 trillion digits. 2,6999,999,990,000 is the previous record.

"So how long is that number? According to the BBC, if you were to recite one number every second, it would you over 49,000 years to reach the end."

2,699,999,990,000/(60*60*24*365) is actually 85,616.438

Yeah. But they said OVER 49,000 years, which includes the exact year amont. I guess that's the "fine print", hehe.

For some reason I did the exact same calculation, came to the same result and wanted to post it here. Good job, you're smarter than the BBC.

Who the F cares?

i wonder what OS he was using....

Fedora Linux 10 64bit.

Interesting i guess, also not to be the police or anything but you forgot to add the word "take" to "it would you over 49,000 years to reach the end" :P

Damn, you beat me to it, lol.

Google with all it's computing power can only come up with 9 digits.... huh.

:)

That is because google is to busy taking over the world to worry about little old Pi

id like to know the algorithm used....

pi = (1/2pi2)5e

if you want to do this yourself, just download SuperPi

That has a 32 Million limit

Oh no.

lol.

But can it run Crysis on high? (sorry couldn't resist)

I lol'ed

I bet he's wrong, just no one can prove it yet.

I never thought of it like that that :haha

Pi

3.14 followed by a bunch of junk that doesn't matter.

thought it was going to say it was an overclocked core i7 with a nvidia card using cuda. I bet a gpu be seriously fast at this.

That's what I thought, start using GPUs for this type of project instead.

ffmpeg woot

mm, pi... when come back, bring pi
