Y-cruncher
Program that computes Pi and other mathematical constants
y-cruncher is a computer program used for the calculation of some mathematical constant with theoretical accuracy limited only by computing time and available storage space. It was originally developed to calculate the Euler-Mascheroni constant 𝛾; the y is derived from it in the name.
From Wikipedia
y-cruncher is a computer program used for the calculation of some mathematical constant with theoretical accuracy limited only by computing time and available storage space. It was originally developed to calculate the Euler-Mascheroni constant 𝛾; the y is derived from it in the name. Since 2010, y-cruncher has been used for all record calculations of the number π and other constants. The software is downloadable from the website of the developers for Microsoft Windows and Linux. It does not have a graphical interface, but works on the command line. Calculation options are selected or entered via the text menu, the results are saved as a file. Some popular uses of y-cruncher are running hardware benchmarks to measure performance of a computer system. An example of such benchmark is HWBOT. y-cruncher can also be used for stress-tests, as performed computations are sensitive to RAM errors and the program can automatically detect such errors.
