• 5 Trillion Digits of Pi - New World Record
    73 replies, posted
[quote] 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: 3. 1415926535 8979323846 2643383279 5028841971 6939937510 : 50 5820974944 5923078164 0628620899 8628034825 3421170679 : 100 2962457053 9070959679 6673211870 6342459769 2128529850 : 999,999,999,950 2976735807 0882130902 2460461146 5810642210 6680122702 : 1,000,000,000,000 9354516713 6069123212 1286195062 3408400370 1793492657 : 1,999,999,999,950 8386341797 9368318191 5708299469 1313121384 3887908330 : 2,000,000,000,000 3840840269 5893047555 2627475826 8598006396 3215856883 : 2,699,999,989,950 9256371619 3901058063 3448436720 6294374587 7597230153 : 2,699,999,990,000 8012497961 5892988915 6174704230 3863302264 3931687863 : 2,699,999,990,050 3126006397 8582637253 6739664083 9716870851 0983536511 : 2,699,999,990,100 5628334110 5221005309 8638608325 4364661745 5833914321 : 2,999,999,999,950 9150024270 6285788691 0228572752 8179710957 7137931530 : 3,000,000,000,000 5209957313 0955102183 1080456596 1489168093 0578494464 : 3,999,999,999,950 3638467628 3610607856 5071920145 5255995193 8577295739 : 4,000,000,000,000 2597691971 6538537682 7963082950 0909387733 3987211875 : 4,999,999,999,950 6399906735 0873400641 7497120374 4023826421 9484283852 : 5,000,000,000,000 Validation File: [url="http://www.numberworld.org/misc_runs/pi-5t/Validation%20-%20Pi%20-%205,000,000,000,000.txt"]Validation - Pi - 5,000,000,000,000.txt[/url] [img]http://www.numberworld.org/misc_runs/pi-5t/8_2_2010_pi_5t_kondo_end_small.jpg[/img] [img]http://www.numberworld.org/misc_runs/pi-5t/8_2_2010_pi_5t_kondo_end.jpg[/img] (Dunno why the CPU voltage is so low, lol) [b][u]Shigeru Kondo's computer specifications[/u] Processor 2 x Intel Xeon X5680 @ 3.33 GHz - (12 physical cores, 24 hyperthreaded) Memory 96 GB DDR3 @ 1066 MHz - (12 x 8 GB - 6 channels) - Samsung (M393B1K70BH1) Motherboard Asus Z8PE-D12 Hard Drives 1 TB SATA II (Boot drive) - Hitachi (HDS721010CLA332) 3 x 2 TB SATA II (Store Pi Output) - Seagate (ST32000542AS) 16 x 2 TB SATA II (Computation) - Seagate (ST32000641AS) Raid Controller 2 x LSI MegaRaid SAS 9260-8i Operating System Windows Server 2008 R2 Enterprise x64[/b] [img]http://www.numberworld.org/misc_runs/pi-5t/10050303.jpg[/img] [img]http://www.numberworld.org/misc_runs/pi-5t/10050301.jpg[/img] [/quote] All I can say is.....

: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?
[IMG]http://i25.tinypic.com/14lhmh1.jpg[/IMG] Oh Goddamn! I bet :20bux: that the next record will be ten trillion digits, calculated on a laptop. [editline]06:02PM[/editline] I better get working....
1900 hours? Linux could do it in 24. [editline]05:05PM[/editline] I'm gonna run away before this turns into a flame war now. [highlight](User was banned for this post ("Troll" - Hexxeh))[/highlight]
I want 2 Xeon processors and 96 GB of RAM... And what the fuck, a 1 TB boot drive? Why :confused:?

Holy fuck, what the hell? Why would you ever want to go further than 3.14 anyway..

[QUOTE=gerbile4;23788325]Go die.

BareMetal OS probably would have been better suited for this.
