Great PI
Super PI is a computer program that calculates the number Pi to a certain number of decimal places, a maximum of 32 million. It uses the Gauss-Legendre integration and is a Windows version of the program with which Yasumasa Canada calculated the number pi to 2 32 digits in 1995 .
Significance for the computer world
The Super PI application is mostly used by users who overclock their computer . On the one hand, the program can be used to determine how fast the computer is absolutely so that the result can be compared with other computers. Above all, the performance of the CPU and the main memory play a decisive role in the result of the calculations. Although Super PI is not the fastest program for calculating the circle number , it is still extremely popular in professional circles.
Falsification of results
In order to achieve better and better results and faster times, some PI results and screenshots are falsified. This results in extremely good values that even the most modern systems cannot achieve in reality. A modified version of Super PI should therefore have integrated a way to validate the results so that forgeries are impossible and errors are detected.
development
When Super PI first appeared, it was designed for single-core processors. In the meantime, however, many CPUs have two or often four or more cores, for this reason Super PI had to be adapted so that all existing cores are now used. This leads to much higher performances and faster times. The program also lost more and more importance due to the increased computing speed and the resulting shorter computing time in the stability test, as it does not run long enough to be able to detect errors or instability. This is why other programs are being used more and more often for such tests.
