Question

In the year 1997 d takahashi and y kanada calculated pi to 51,539,600,000 decimal places. what type of computer did they use? where did they do the calculations

Answer 1

Takahashi and Kanada did their work on the digits of pi at the University of Tokyo in what is called the Computer Center. They developed a computer algorithm (a set of steps/procedure) that delivered the digits in 29 hours and 7 minutes.

They used a computer called the HITACHI SR2201 which has 1024 processors. As an example most desktops in use now (by individuals such as you and I -- not by computer scientists doing research) have 1-2 processors with 2 cores each.
