The increase in productivity and reliability of computer systems took place in two ways. The first way is the improvement of hardware. The second way is the implementation of new architectures and principles of arrangement of computing processes. The second way is the most promising and relevant in terms of improving the productivity and reliability of computer systems. The organization of the computing process in a multiprocessor computing system is the perfect if all system resources, both hardware and software, are used efficiently, and the system’s performance is as high as possible. However, such an organization requires many efforts to implement. In order to reduce these efforts, some simplifications are sometimes made. It is necessary to distinguish between two modes of operation depending on the performance of the multiprocessor computing system and its dependence on the number of computing modules that are included in the system. Processors, single-chip micro-computers can be used as modules. Currently, the development of multiprocessor computing systems is one of the important and relevant directions of improving the productivity of computing devices.
