HOW TO DEMONSTRATE PUPILS VISUALLY THE ADVANTAGES OF MULTIPROCESSOR SYSTEMS
A problem of working out a concordance is considered in the article as a demonstrative example of parallel data processing. The software imitator, visualizing a progress of calculations on an ordinary PC’s screen, is developed to demonstrate an execution of solution’s algorithms. Material is intuitively clear, together with the software support it may be used for explanation of parallel technologies advantages to pupils at school.
Keywords: parallel processing, multiprocessor systems, example, course content, concordance.
