TachusPI Download

Here is the program used to compute the 2700 billion digits of Pi. I only maintain the Linux version. I just compiled a Windows executable but I never really used it: you are warned. You must have a 64 bit OS to use this program.

Linux executable tpi-0.9-linux.tar.gz
Windows executable tpi-0.9.3-win.zip
