The analysis of functioning of the distributed real-time computing system

The questions of the analysis of operating characteristics of the specialized distributed computing systems working in real time are considered. Tasks carried out on the system are frequently repeating and have known cyclic or final time. Such systems have appeared in the field of application of mobile platforms. For such systems we will note two major characteristics: task delay time and time of use of system. The analysis of operating characteristics is based on methodology of the theory of queues. The results include comparison of various disciplines of service.
