Abstract. The possibility of reserved service of copies of requests critical to delay is studied for duplex computer system of cluster architecture with sequential execution of queries (first at the cluster nodes lower, then at the upper level). An analytical model is presented for estimation of probability of timely service of requests for the case when the total waiting time for upper- and low-level nodes does not exceed a preset limiting value, and no errors and crashes occur during the stay of the queries requests critical to delay both levels. Effectiveness of reserved service is evaluated for requests critical to summarized waiting delay in the upper- and low-level nodes. Areas of effective application of the proposed approach to reserved service copies of requests are described, and optimal multiplicity of the requests copying is determined.
Keywords: cluster, two-level system, the probability of timely service, reservation, reservation multiplicity, queueing system
