Benchmarking program – Super Pi
Super PI is a benchmarking software that tell how much time a computer takes to calculate value of pi to a specified number of digits after the decimal point. The Super Pi 1M result means how much time a computer takes to calculate the value of Pi to 1 million digits after the decimal.
There are similar Super Pi 2M and Supper Pi 32M results and are used to describe the speed of a computer, especially for its processor. A smaller number means faster processor. Usually a processor with higher clock in the same series will take smaller time.
The Super Pi uses Gauss–Legendre algorithm. The Super Pi is very common among the overclockers community to showcase how fast their system is.
Criticism
Super Pi is more suited to the single threaded processor and it does not take into account the multi processing and multicore capability of the processors. It is criticized that the Super Pi does not reflect the real world multi processing, multi core capable modern processors.
How to calculate the Super Pi for your system.
To calculate the Super Pi for your system, download the Super Pi program from
ftp://pi.super-computing.org/windows/super_pi.zip
Unzip it and run the Super Pi program. You can select the number of digits upto which the Super Pi needs to be calculated. The 1M and 2M are most common Values. You may also run 32M, but it may take long – typically 15 minutes.
As and example the Super Pi 1M figure using the computer being used to write this article ( It is an Intel Core i3-350M processor at 2.27 GHz), while running on battery was found to be 20 seconds. The figures for the Super Pi 2M was found to be 48 seconds.

Very Nice information. I believe everyone should check their Super Pi Score. Here is mine
My Presario CQ62 took 28s for 1 M and took 1 min 15 seconds for 2M. It has intel Celeron 900 CPU ( 2.2 GHz)
Cool info My celeron M 530 1.73GHz took 38s for 1M
my intell core 2 quad q6600, overclocked from 2.4ghz to 3.1ghz does 1M in 18 seconds, and 2M in 39 seconds
Intel Core i7-930 2.8GHz, 1m in 15 seconds, 2m in 32 seconds. However, neither of my widgets that tell me CPU usage showed up pushing it past 20% which leads me to believe it doesn’t have multi-core support
Intel i5-2500K (not overclocked) 1M in 10 seconds, 2M in 25 seconds, 4M in 57 seconds. I’ll post the overclocked at 4.5GHz results soon.
TampaJoey, great to see 1M knocked down in 10 seconds. Can’t wait to see Super Pi 2M overclocked score.
The superPI is my favorite benchmark program, unfortunely it is use only one core,
than i write superPI who use up to 16 cores. May try it http://www.benchlab.org/downloads

I tried to use this program and it says
This application has failed to start because MSVCR71.dll was not found. Reinstalling the application may fix this problem.
hm very strange it is portable no need reinstall just start multicore_superpi.exe
what is your OS? Did you see MSVCR71.dll in the same multicore_superpi.exe folder
Mona, just extract zip in separete folder and run multicore_superpi.exe
posible you start program directly inside from zip arhive
