Parallel Programming in PC and Computer Cluster Environment – Selected Computational Problems

Parallel programming is a skill that requires the use of technologies and techniques that allow applications to use multiple threads/processes simultaneously. In some cases, this is a condition for their launch or correct operation. This article presents selected aspects of such a programming using the example of two proposed applications: for PC computers with the .NET platform and application designed for a computer cluster operating in the GNU/Linux system. These are two applications with different purposes – the first uses image processing mechanisms, while the second – is the implementation of precise numerical calculations. The proposed applications were designed in the context of using multithreading and multiprocessing technologies. The obtained results indicate that implementing appropriate programming techniques is an important aspect of programming various types of applications, ensuring their correct operation and acceleration of long-term calculations.
