Help us and contribute to the pi(x) computation project.

Current computation is pi(x) for x = 10²³

New : Version 1.6 is now available (computation time has been reduced in the B part, for a global saving of   15%, precomputation of chunks in the A, B and C parts is always done to optimize independance of chunks).

Requirements

You just need a computer with a pentium or equivalent chip, turning on windows 95, 98 or NT. Several memory mode exists, so that even computers with only 30 Mo of free memory can help. No permanent connection to internet is needed.

How to contribute to the pi(x) project

• Download the dos executable file pix.exe This is version 1.6, and this is needed for our current computation.

• Download the data files Achunks.txt, Bchunks.txt, Cchunks.txt, Dchunks.txt, and MasterRanges.txt (click on the right mouse bouton to download those text files directly) and put them in the same place where pix.exe is. These files contains parameters to compute chunks for the current computation.

• Reserve your chunk(s) (see below).

• Run pix.exe with your reserved ranges and send the small resulting files to xavier.gourdon@free.fr. Your name will be added in the contributor list soon after the resulting files have been sent.

Reservation has been improved since the computation of pi(10²³) :

• You enter your name at your first reservation to become a contributor (see here).
• Reservations are done with your pseudo.
• You can have access to the list of your reserved chunks (see here).
• No email confirmation is needed now for reservation with more than 3 chunks (but as always, results should be send in one week).
