THE BEST PI PLACES

The links below take you to the home pages of
Xavier Gourdon, Takuya Ooura, Alan Pittman
Carey Bloodworth, Mikko Tommila, Steve Pagliarulo, Sebastian Wedeniwski,
Gio Ciampa, and Yasumasa Kanada
as well as other interesting places about 3.14159....

  • Fabrice Bellard
    • Home to the world's 2nd place record calculation on *any* computer (his was a home computer), 2,699,999,990,000 digits - 31 Dec 2009

  • Daisuke Takahashi
    • Home of the third largest calculation of p, and the largest on a super-computer.
    • 2,576,980,370,000 digits - August 2009

  • Xavier Gourdon
    • Home to the fastest p program on the planet for the PC.
    • Also home to a former size record holder for number of digits of p calculated on a home computer - 17,100,000,000 digits (15.93-gigs) - record computation by Shigeru Kondo using PiFast 4.3, see Size Records/Home Computer for details

  • Dara's Pi page
    • Dara specializes in porting the opening source programs to other operating systems, including (mainly) Linux and the Mac OS.
    • A good set of links, plus all the info you'd ever need on our blessed digits.
    • Please see Dara's chart for another comparison of ALL these programs and more, run on Linux.....

  • University of Tokyo FTP site
    • Home of the eighth fastest p program for the PeeCee- Super-Pi.exe by Yasumasa Kanada et. al.
    • Latest record for digits on a supercomputer - 1,241,100,000,000 - November 2002

  • Alexander Yee's y-cruncher
    • Record holder for size of pi-calculations on both a home PC and supercomputer, 5,000,000,000,000 digits
    • a high-school project that went a little too far
    • scalable multi-threaded Pi-benchmark for multi-core systems
    • 1 billion digits of Pi in 10 minutes on 3.33 GHz Core i7
    • Version 0.5.4 Build 9146 Alpha (Released: August 2, 2010), allows Pi computations of up to 5 trillion digits. (Credit to Shigeru Kondo)

  • Shigeru Kondou
    • Record holder for size of pi-calculations on both a home PC and supercomputer, 5,000,000,000,000 digits using Alexander Yee's y-cruncher
    • in Japanese (with an English section)

  • Jason's pile of pi programs
    • Home to Carey Bloodworth'sp programs and source code - also your one-stop shopping for all sorts of other p source code and all other p programs (Note: the page is a little out of date.)

  • Apfloat page
    • Home of the fourth fastest p program for PeeCee - Mikko Tommila's Aploat large integer package which comes with Aptest, his world ranking pi calculator
    • Also applets for calculating pi on a Web browser are available on-line. The Java version has some support for multithreading, and even a distributed pi calculation program is available (thanks to Java's support of threads and networking). Otherwise the performance is around 50% of the assembler-optimized C++ apfloat versions (when using Sun's Server VM).

  • Joerg Arndt's HFloat
    • Large integer multiplication package

  • L'univers de Pi
    • si les pages consacrées aux mathématiciens se veulent détaillées, rien ne vaut une petite synthèse de l'historique de Pi. Avec Pi, la machine à explorer le temps est une réalité... Mais bien sûr, pour plus de commodités, le langage moderne et habituel des mathématiques est utilisé ici... par Boris Gourevitch @ boris.gourevitch@ensai.fr
