Abstract

Possible ways of increasing the probability of timely and faultless execution of delay-sensitive requests in real-time clustered computing systems, when multiple copies of requests are created and served in different cluster nodes, are investigated. The proposed models for queueing and functional reliability prove the existence of scope of efficiency for service disciplines with redundant execution of copies of requests, when the probability of their prompt and error-free servicing can be increased significantly, despite the rise of load in the nodes. It was examined how the ways to arrange redundancy and the redundancy order affected timely and reliable servicing of requests, with possible faults and errors in the nodes. It was shown that destruction of expired copies, whose waiting time in the queue exceeded a given ultimate time, and copies which became irrelevant, after one of them had been processed, produced an essential enhancement of efficiency of the system.
