Super PI

Super PI

pi 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 and called Super PI. In order to calculate 33.55 million digits, it takes within 3 days with Pentium 90MHz, 40MB main memory and 340MB available storage.


With Super PI, we can actually measure how fast our CPUs by measuring the amount of time it takes to compute PI. The lower the time-to-compute, the faster your PC. Here’s the result in my P4 3.02E GHz with 512 MB RAM.

00m 01s [ 64K digits]
00m 04s [ 128K digits]
00m 09s [ 256K digit]
00m 22s [ 512K digits]
00m 48s [ 1M digits]
01m 55s [ 2M digits]
