Super PI is a famous computer program that can calculate pi to a specified number of digits after the decimal point - up to a maximum of 32 million.

Super PI will use FFT arithmetic and Borwein's quartically-convergent algorithm and is a Windows port of the program used by Yasumasa Kanada in 1995 to compute Pi to 232 digits.

Super PI also uses x87 floating-point unit, so it will favor processors with good FPU performance, such as AMD Athlon 64, Intel Core 2.

In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo.

The program was written by D.Takahashi and he collaborated with Dr. Y.Kanada at the computer center, the University of Tokyo.

This record should be the current world record.

This record-breaking program was ported to personal computer environment
such as Windows NT and Windows 95.
In order to calculate 33.55 million digits, it takes within 3 days with Pentium 90MHz, 40MB main memory and 340MB available storage.
