Portable System Stability Tester

Designed to calculate up to 128 million digits of Pi, System Stability Tester is a C++-based application that tests the system’s stability. It works on a wide range of OSes such as Linux, Linux Alpha, Tru64, Solaris, AIX, macOS, and Windows (including the old Win32 NT series).

In short, the application can create up to 32 threads, it automatically recognizes the CPU model, the manufacturer, and operational frequency (either x86 or x64), compare the calculation results of all the threads after each step, and issue appropriate warnings if something did not go as planned.

What’s more, System Stability Tester can also run continuously for up to 50 turns and log the results after each step and after each turn. All the recorded digits of Pi are neatly saved within a readable text file.

Also important to note is the fact that the app supports multiple calculation algorithms. For starters, it supports the Quadratic Converge of Borwein, and the Gauss-Legendre, the algorithm another similar app, SuperPi, uses.

Each process of testing involves the creation of two or more threads. After each step, the results of all the threads are compared back to back. The app also provides users with a single-threaded calculation procedure, but this method is not particularly relevant in terms of determining a system’s stability (only for general benchmarking purposes).

Taking everything into account, there’s no denying that System Stability Tester, an app designed somewhere in 2005, is a bit outdated by today’s modern standards. Nevertheless, it still works on modern computers with modern OSes just fine. What’s more, thanks to its user-friendly GUI, it can be used just as efficiently by even the most novice of users out there.
