- 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.....

- 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- also your one-stop shopping for all sorts of other p source code and all other p programs (Note: the page is a little out of date.)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).

- 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 @ firstname.lastname@example.org
